Managing noise and preventing hearing loss, ohscmcvellore
Occupational hearing loss and prevention
Hearing loss can be caused by occupational noise exposure in various industries such as construction, manufacturing, and military. Noise from sources like power tools, machinery, and weapons can damage hearing over time. Musicians are also at risk from loud music. Prevention methods include monitoring noise levels, conducting audiometric testing, raising awareness of noise hazards, and using hearing protection like earplugs and earmuffs. Hearing loss is cumulative and permanent damage can occur even from moderate noise levels with regular exposure over years. Employers should implement noise control measures and hearing conservation programs.
This document discusses hearing conservation and protection. It notes that excessive noise can damage hearing, leading to tinnitus and hearing loss. There are three main types of hearing loss: presbycusis which occurs naturally with age; temporary hearing loss from short-term loud noise; and permanent hearing loss from long-term noise exposure. Construction work involves high noise levels from tools, and workers must wear appropriate hearing protection like ear plugs or muffs to limit noise exposure and prevent permanent hearing damage and potential workers compensation claims later in life. Regular audiometric testing is also required to monitor workers' hearing health.
This document provides an overview of occupational noise exposure and hearing conservation training. It notes that about 30 million American workers are exposed to hazardous noise on the job and that noise-induced hearing loss is a common occupational hazard. The document defines noise, discusses how exposure can lead to temporary or permanent hearing loss, and outlines the anatomy of the ear. It also covers signs of hearing loss, types of hearing protection devices, proper fitting and use of devices, audiometric testing requirements, and access to information about noise exposure standards.
Noise-induced hearing loss is the number one occupational disability and is generally caused by exposure to loud noises over time. It is permanent but preventable. Using hearing protection devices like earplugs and earmuffs can prevent noise exposure above safe levels from damaging hearing. Proper use and care of hearing protection, limiting exposure time to loud noises, and following safety guidelines are important to preserve long-term hearing ability.
This document discusses occupational hearing loss prevention. It covers topics like permissible noise exposure limits, types of hearing protection devices, audiometric testing procedures, and training requirements. The goal is to educate about noise-induced hearing loss and how to implement controls and testing to protect worker hearing.
This document discusses noise-induced hearing loss and prevention methods. It notes that hearing healthcare professionals often overlook prevention. Two questions are presented to help patients appreciate their hearing senses: favorite color and favorite sound. Regulations from OSHA on hearing protection in noisy workplaces are covered. Various types of hearing protection devices are defined, including earplugs, earmuffs, and dual protection. Proper insertion techniques for earplugs are emphasized. Risk factors for noise-induced hearing loss are noise level, duration of exposure, and individual susceptibility.
Noise-induced hearing loss is the number one occupational disability and is generally painless and progressive over time. It is caused by exposure to hazardous noise levels through either acute acoustic trauma or daily exposure to moderately loud sounds. While initially affecting high frequencies, continued exposure can damage mid-frequencies resulting in the inability to understand speech. Using hearing protection devices can prevent noise-induced hearing loss. Common types of hearing protection include earplugs and earmuffs, which should be properly fitted and maintained to be effective. Administrative controls and doubling up protection may also be needed for very high noise exposures. Annual hearing tests are important to monitor any effects of noise exposure.
The human ear is designed to receive sound waves and transmit vibrations through three parts - the outer, middle, and inner ear - to the brain for interpretation. Exposure to loud noises like clubs that require shouting can damage hearing at levels over 100dB for 30 minutes or less. Damage to hair cells in the inner ear can lead to tinnitus, a ringing or buzzing perceived as sound by the brain. Symptoms of hearing loss include difficulty with conversation and perceiving certain sounds. The best way to prevent noise-induced hearing loss is through proper use of hearing protection during loud work to avoid permanent damage for which there is no cure.
BRAMHOPE HEALTH & SAFETY - HEARING PROTECTIONBramhope Group
Noise-induced hearing loss is a common occupational hazard caused by insufficient ear protection from high noise levels. Permanent workplace noise pollution can also cause stress, loss of productivity, and inability to concentrate. Bramhope Health & Safety offers a range of hearing protection products suited for different workplace noise hazards. Proper hearing protection is required above 85 dB noise exposure and should lower noise levels to 70-80 dB for the wearer. Common hearing protection options include earmuffs that cover and seal around the ears, and earplugs that are inserted into the ear canal.

The document discusses noise hazards in the workplace, identifying noise levels over 85dB over an 8-hour period as hazardous. It describes how noise causes hearing loss by damaging delicate hair cells in the inner ear, and lists various common sources of noise in industries like manufacturing, construction, and agriculture. Prevention methods covered include engineering controls that modify equipment, administrative controls that limit exposure time, and providing personal protective equipment.
Concern is growing about the rising exposure to loud sounds in recreational settings such as nightclubs, discotheques, pubs, bars, cinemas, concerts, sporting events and even fitness classes. With the popularization of technology, devices such as music players are often listened to at unsafe volumes and for prolonged periods of time. Regular participation in such activities poses a serious threat of irreversible hearing loss.
Dr. Tony Evans gave an educational seminar about hearing loss and hearing aids. He discussed how hearing works, types of hearing loss, evaluating hearing loss, and modern hearing aid technology. Hearing aids have advanced significantly and can now be customized to the individual user's hearing loss and lifestyle. Attendees learned that early intervention and use of the right hearing aids can help people reconnect to their world by improving communication and quality of life.
The document discusses hearing conservation and protection. It notes that continuous exposure to excessive noise can cause permanent hearing loss. Repeated brief exposures can also lead to permanent threshold shifts over time. Hearing protection like earplugs and earmuffs, when properly worn, can reduce noise exposure below 85 decibels to prevent hearing loss. The types, advantages, disadvantages, proper use, and maintenance of different hearing protection options are described. Audiometric testing is recommended to monitor any changes in hearing ability from noise exposure.
The Importance of Wearing Ear ProtectionClay Hutson
Exposure to loud noise can cause permanent hearing loss over time. Prolonged exposure to sounds over 85 decibels, such as lawnmowers, construction sites, or explosions can damage the tiny hairs in the inner ear. Wearing ear protection like earmuffs or earplugs can help reduce noise exposure and prevent further hearing damage. Employers should also take steps to limit worker noise exposure through barriers or scheduling noisy work when fewer employees are present.
Noise pollution is a growing problem in Asia that can damage hearing and health. Sound is measured in decibels, with over 70 dB considered unsafe over long periods. Common noise sources include vehicles, construction, entertainment venues, and domestic noise. Prolonged loud noise can cause hearing loss, stress, sleep issues, and learning problems for children. Authorities should educate the public and restrict unnecessary noise sources like vehicle horns to address this important issue.

It provides background on the fragmented traditional credentialing system and outlines attributes of a new, learning-based system using digital badges. Badges provide portable, transparent credentials for skills obtained in various learning environments. Colorado's initiative aims to issue badges in technical areas like math, machining, and engineering based on industry-defined competencies. The badges provide evidence of skills to help learners and employers. Challenges to digital badges becoming mainstream include lack of awareness, but many institutions and companies now issue or accept badges.
This document discusses the use of digital badges to recognize skills and competencies in the workforce. It notes that today's credentialing system is complex and difficult to understand for employers, individuals, and educators. Digital badges can provide a learning-based alternative that is learner-centered, competency-based, and industry-driven. The Colorado Community College System is piloting the use of digital badges in several technical areas like math, machining, and engineering graphics. Badges can help provide transparent, portable credentials that map to specific skills and allow learners to showcase competencies across different programs and throughout their careers.
CCCS and CSU Digital Badge presentation at Aurora Badge Summit June 2016cccscoetc
Colorado State University Online and the Colorado Community College System are working to create a digital badge ecosystem across higher education institutions and industry in Colorado. The ecosystem is intended to provide transparent, portable credentials for learners through competency-based micro-credentials. It began in 2013 in response to needs from industry for shorter training turnarounds and a more credentialed workforce. Early collaborations established principles of learner-focused, community-centered and industry-driven badges, and a structure was developed to connect competencies, curriculum maps and badge graphics. Pilot programs issued over 130 badges from 2014-2015. Efforts continue to expand industry recognition of badges and connect badges to credit-bearing pathways and degrees.
CCCS Digital Badging Taskforce Whitepaper BMP 1130cccscoetc
The document discusses establishing a digital badge system within the Colorado Community College System (CCCS). It proposes that CCCS can leverage digital badges or micro-credentials to document skills and provide a portable verification of competencies. The document outlines challenges in selecting a badge platform, developing processes and frameworks, and increasing demand. It recommends implementing a pilot program within 6 months using $5,000 in funding to select one of the top badge platforms and develop a pilot for Technical Math for Industry digital badges.
Northeastern Junior College-Nacelle Wind Power Generation Labcccscoetc
A wind turbine nacelle donated to NJC was assembled on site to create a lab environment simulating an actual turbine. With donations of gearboxes, generators, and other components from industry partners like GE and Infigen, as well as funding from NJC and a grant, students designed electrical and pitch control systems to automate functions like lubrication and temperature control. By winter 2015, students had completed schematics and begun building automated control panels to operate mechanical systems that will provide hands-on experience for the wind technician program.
This document describes an HVAC gaming simulation project between Red Rocks Community College and Pikes Peak Community College. The project aims to gamify an existing HVAC simulation software to motivate students and allow for hybrid HVAC courses. A gamification engine would add badges students can earn for completing different equipment tasks and a leaderboard to track earnings. The schedule outlines developing and testing a prototype in 2013, with the goal of expanding its use in additional HVAC courses through 2014.
Jumping Into the Deep End: CCCS' Success At Moving CTE Courses to Blended Cou...cccscoetc
CCCS successfully moved many Career and Technical Education (CTE) courses to blended/hybrid formats. Originally only 15 of 122 relevant courses were hybrid, but a deadline of December 2013 required all 122 be hybrid. CCCS developed a plan with the following steps:
1) Analyze certificates and courses, identifying high-enrollment and certifiable courses for hybrid conversion.
2) Create a course development plan with benchmarks and incentives for colleges to share hybrid courses.
3) Work with faculty through onsite instructional designers to "chunk" content into online and hands-on activities, and assess quality.
4) Publish hybrid courses openly online to increase enrollment in certificate programs and meet industry demands within
Faculty voices presentation at ALP Baltimore June 2014cccscoetc
Presentation given at ALP annual conference in Baltimore, MD, June 2014 on the publication "Faculty Voices". Faculty Voices is funded through a TAACCCT 1 grant. The grant focused on energy course redesign and the redesign of all developmental education courses in the Colorado Community College System.
Morgan Community College's Hybrid-Electric Simulator Portfoliocccscoetc
Morgan Community College's portfolio showcases simulation equipment automotive students learn about vehicle systems and in particular hybrid automobiles.
This document provides information about a quantitative literacy course called MAT 050. It is a hybrid course designed for students planning to take other math courses. Students will spend about 12 hours per week on course material, including 2-3.5 hours in class and the remaining hours outside of class. The course uses an online learning platform called D2L and online homework system called My Math Lab. Students will have access to course resources like power point presentations, online tutoring, and help centers. Assessment includes group activities, homework, quizzes, tests, and a final exam. Students are expected to complete practice problems, activities, and homework each week.
The document outlines several changes and updates to instructional methods. Scaffolding is described as a learning process that provides support tailored to student needs to help them achieve learning goals, with supports gradually removed as students develop independent strategies. Note-taking no longer requires template collection. Videos replace textbooks and will not have associated problems collected. Group work will still be collected but allows selecting two assignments weekly. Homework can also select two assignments weekly but does not require complete sentences. Online homework will now be graded directly rather than collecting printouts.
Unit 3 focuses on getting students ready for transfer level courses through flipped teaching with math videos students must watch before class. The instructor will check that students watched videos and took notes in each class, no longer providing note templates. Group work will now be graded in class with students earning points for participating, and cannot be made up if absent. Homework from the textbook and online platform will no longer be collected, though similar questions may appear on exams.
This document provides instructions and examples for factoring trinomials and binomials. It begins with an introduction to factoring trinomials of the form ax^2 + bx + c. It then gives examples of factoring different types of expressions, including factoring out negatives, dealing with two variables, and factoring completely. It concludes with a list of homework problems from the textbook for further practice factoring expressions.
FRCC MAT050 Dividing by a Monomial (Sect 3.10)cccscoetc
This document discusses dividing polynomials by monomials. It provides examples of dividing terms with variables by monomials, including factoring out negatives. The homework assignments are to complete odd problems from pages 297 and 303 of the textbook, with no additional problems from an online system.
FRCC MAT050 Linear Inequalities (Sect 3.9)cccscoetc
This document discusses linear inequalities and their properties. A linear inequality is any relationship of the form ax + b, where a is not equal to 0. The key points covered include:
- Linear inequalities can use the symbols <, >, ≤, or ≥ to represent relationships.
- When multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality symbol flips.
- Graphing linear inequalities results in solutions represented by regions on a number line.
- Compound inequalities involving AND or OR statements can be solved by evaluating each inequality separately and combining the solutions appropriately.
This document outlines the steps to solve formulas in Section 3.8, including group work to explore problems on page 272 numbers 1-8, a class discussion of how it works using problems on page 274 numbers 9-11, and homework assignments of problems on page 279 numbers 1-12 and the My Math Lab Section 3.8.
FRCC MAT050 Equations of Lines (Sect 3.7)cccscoetc
This document provides instructions for group work and homework on equations of lines. Students are asked to explore examples of writing equations of lines and describe how it connects to group work. For homework, students should complete selected problems from the textbook on how to write equations of lines without using the online system My Math Lab.

2. Did You Know?
About 30 million workers are exposed
to hazardous noise on the job. One in 4
of these workers (or 7.5 million
Americans) will develop permanent
hearing loss.
Noise-induced hearing loss is the most
common occupational hazard for
American workers
Hearing loss from noise is slow and
painless; you can have a disability
before you notice it
If you must raise your voice to speak
with someone only 3 feet away, you are
in high (hazardous) noise.
It is 100% preventable
3. Noise Exposure At Work
1. Identify potential sources of
hearing loss
2. Learn how to prevent
hearing loss at work
3. Meet regulatory
requirements
4. The purpose of audiometric
testing and how it works
This presentation will cover the following topics:
Noise Exposure at Work
4. How is Noise Measured?
Noise levels are
measured in decibels
(dB)
Decibels are not linear
measurements
The difference in energy
between 100 decibels
and 110 is not 10% -
actually is 100 times the
sound level pressure
5. Effects of exposure to loud noise
Exposure to loud noise will
inevitably cause hearing loss over
time.
Once the nerves of the inner ear
are destroyed or damaged from
exposure to excessive noise, the
damage is permanent
Loud noise damages or destroys
the nerves in the inner ear.
Another effect can be “tinnitus” or
permanent ringing in the ear.
6. Factors Affecting Hearing Loss
The following factors can affect
hearing loss:
Noise Intensity or Sound Pressure
Frequency or Pitch of sound
Length of Daily Exposure
Duration of Exposure in Years
Individual Susceptibility
Other Factors (disease, genetics,
lifestyle, age, etc.)
7. When is Noise Too Loud?
• Noise is measured in
units called “decibels” or
“dB”
• If two people 3 feet apart
must shout to be heard,
the background noise is
too loud (above 85
decibels).
• Noise above 140 decibels
causes pain and
immediate hearing loss.
8. Signs of Hearing Loss
Difficulty hearing people speak.
Inability to hear certain high-pitched or soft
sounds.
Noise or ringing in ears.
Getting complaints that the radio or TV is too
loud.
9. Long Term Exposure to Noise
• Our ears can recover
from short exposure to
loud noise, but over time
nerve damage will occur.
• The longer and louder
the noise, the greater
chance permanent
damage will occur.
• There is no such thing as
“tough ears” or “getting
used to it”.
10. Effects of noise to inner ear
Normal hair cells Noise-damaged hair cells
Hair cells in inner ear transmit noise signals to the brain
11. Tinnitus From Noise Exposure
• Exposure to high noise levels
can also cause permanent
ringing in the ear or “tinnitus”.
• Tinnitus sufferers usually
complain of constant whistling,
squealing, roaring or buzzing
in one or both ears.
• Severe tinnitus may disrupt
sleep, reduce concentration
and cause irritability and
depression.
12. What is Too Much Noise Exposure?
• Damage from noise exposure
depends on the loudness and
length of exposure.
• Scientific studies have shown
that hearing loss can occur
when 8-hour average noise
exposure exceeds 85 decibels.
• The risk of hearing loss
increases dramatically as
noise levels increase.
• Exposure to noise levels above
115 decibels for even five
minutes is very risky.
13. OSHA Standard
If 8-hour average exceeds 85 dBA
then the employer must:
1. Monitor (measure) exposure and
notify employee of the results
2. Provide audiometric testing
3. Provide hearing protection
4. Provide training
5. Keep records of monitoring and
audiometric testing
14. Daily Allowable Exposure Times to Noise
The table below shows noise levels and how long a
person can be exposed without hearing protection
before there is damage to the ear.
Noise Level Allowable Exposure Time
85 decibels 8 hours
90 decibels 4 hours
100 decibels 1 hour
105 decibels 30 minutes
110 decibels 15 minutes
115 decibels 0 minutes
15. Examples of Common Noise
Exposures
Source dBA
Whisper 20
Refrigerator 40
Conversation 60
Average TV 74
Blender 80
Source dBA
Ipod 90
Woodworking 93-120
Gun Shot 130-140
Riding Motorcycle 90
Snow Mobile 120
Rock Concert 140
16. Examples of Noisy Equipment
Equipment Noise Level
Back Hoe 85-95 decibels
Chain Saw 110 decibels
Front-end Loader 90-95 decibels
Gunshot 140 decibels
Jackhammer 112 decibels
Lawn Mower 90 decibels
Tractor 95-105 decibels
Circular Saw 90-100 decibels
Below are some examples of noise levels of various
equipment used on campus without the use of hearing
protection.
17. Noise Levels and Permissible Exposure Levels
Without Hearing Protection
Chiller Buildings 14 hours
Router 97 dBA 3 hour
Radial arm saw 105 dBA 1 hour
Table saw 96 dBA 3.5 hours
Portable belt sander dBA 100 2 hours
Below is the maximum amount of time a person
can spend exposed to this equipment without
hearing protection.
18. Examples of Noisy Areas at UT
Campus
Machine Rooms and Chiller Rooms
Steam Plant
Wood working shops
Motor Pool
Operating heavy equipment, such as
backhoes, bull dozers
Construction equipment, such as: table
saws, radial arm saw routers, belt sanders,
drills
Landscaping equipment, such as
lawnmowers and leaf blowers.
19. Noise Control Measures
The employer must take some steps to control
noise exposure in the workplace, such as:
Identifying noise hazardous equipment.
Using Engineering, Administrative and Hearing
Protection to minimize or eliminate noise
exposure.
Modifying the source of the noise so it is
quieter, using engineering controls.
Increasing distance between the employee and
the noise hazard.
Limiting worker exposure time.
Requiring the use of hearing protection devices
when the above measures are not feasible
and/or do not decrease noise levels below a
TWA-8 of 85 dBA.
20. Engineering Controls
Engineering controls are
the most preferred option
in reducing or eliminating
the noise hazard by:
Reducing or eliminating noise
at the source.
Interrupting the noise path.
Reducing reverberation and
structural vibration.
21. Administrative Controls
If engineering controls do not work to
eliminate the noise hazard, then
administrative controls should be
considered:
Operate noisy equipment on second
or third shifts.
Rotate employees through high-noise
areas.
Modify existing machinery.
Place noise limit specs. on new
equip.
Maintain equip. in good condition.
Use noise control when installed.
Reporting noisy equip. to supervisor
for repair.
22. Personal Protective Equipment
If engineering or
administrative controls do
not work to eliminate the
noise hazard, then
personal protective
equipment should be
considered as a last
resort.
This includes using
hearing protection, such
as ear plugs or ear muffs.
23. There are three types of
hearing protection – ear muffs,
earplugs and ear caps.
Ear muffs and earplugs provide
about equal protection, ear
caps somewhat less.
Types of Hearing Protection
earmuffs
earplugs ear caps
24. All hearing protectors are
designed to reduce the intensity
(loudness) of noise to the inner
ear.
They work much better than
wads of cotton or bits of cloth
stuffed in the ear.
All three types have advantages
and disadvantages and people
vary on which they prefer to
use.
Types of Hearing Protectors
Cotton doesn’t
work!!
25. Earplugs are made of foam,
rubber or plastic and are either
one-size-fits-all or in sizes
small, medium and large.
Some are disposable, some are
reusable.
They are lightweight, and
require no maintenance.
They are inserted into the ear
canal.
Hearing Protection – Ear Plugs
26. Some people may find ear
plugs uncomfortable to wear
for long periods at first.
Ear plugs rarely cause infection
or prolonged irritation of the
ear canal.
Most people can find a
comfortable fit by trying
several different sizes, types or
brands.
Custom-molded earplugs can
be obtained for maximum
comfort.
Ear Plug Comfort
custom molded
earplugs
27. Foam type earplugs are one-size-fits-all and
must be inserted properly into the ear.
Inserting Foam Earplugs
Roll earplug into small cylinder first, then insert in ear.
29. Ear muffs cover the whole
ear and are preferred by
some people.
They have replaceable
pads and some high-tech
styles filter out specific
noise pitches.
They last longer than most
plugs.
Ear Muffs
30. Some muffs are attached to
hard hats or goggles.
Some high-tech muffs can
filter out certain frequencies
or have radios inside for
communication in high noise
areas.
Attached Earmuffs
31. Muffs can be
uncomfortable in hot
weather.
Muffs don’t seal well for
someone with glasses or
heavy sideburns.
Ear Muff Comfort & Glasses
32. Ear caps are like
earplugs, except they
do not go into the ear
canal, they only block it.
They are good for
occasional use or for
people who find
earplugs uncomfortable.
They are not as
protective as earplugs
or muffs.
Ear Caps
33. The “noise reduction
rating” or “NRR” of
hearing protection is
measured in decibels.
The NRR is found on
the earmuff or earplug
package. The higher
the number, the
greater the protection.
Noise Reduction of Hearing Protection
34. Using earmuffs or plugs in
noisy areas can actually
make it easier to hear
coworkers or machinery.
They reduce overwhelming
loud background noise.
They are similar to dark
glasses that reduce the
sun’s glare making it easier
to see.
How can you hear anything
with earmuffs on?
35. Earmuffs and plugs
provide good protection
only when used
properly.
Sometimes people will
remove hearing
protection for “just a
minute” in a noisy area.
In areas of very high
noise exposure, this
could result in noise
overexposure.
Proper Use of Hearing Protection
It won’t protect your ears if
it is around your neck!!!
36. Instructions on Selection, Fitting, Use,
and Care of Hearing Protectors
Ear plugs
Keep clean and free of materials
Wash in mild liquid detergent and warm
water
Squeeze excess water and air dry
Discard plugs when hardened or do not
re-expand
Ear Canals
Clean like normal ear plugs
Do not tamper with the headband and
the acoustic seal
37. Instructions on Selection, Fitting, Use,
and Care of Hearing Protectors
Ear Muffs
Keep clean and free of debris
Clean cushions with warm soapy water
Do not tamper with the acoustic seal
between the cushions and the
headband
Do not modify the ear muffs in any
way
Do not stretch or abuse the
headband
38. It takes just a few minutes
of unprotected exposure at
noise above 115 decibels
to risk hearing damage.
Earplugs not well inserted
into the ear canal will not
provide complete
protection.
Likewise, earmuffs not
snug against the head will
“leak” noise into the ear.
Proper Use of Hearing Protection
39. Hearing aids do not block out
enough sound for most
workplace noise.
Some hearing aids can
actually increase the noise
level at the ear.
Just turning off the hearing
aids will not prevent further
hearing loss from noise
exposure.
Hearing Aids Are Not Hearing Protection
40. Portable Radios/CD Players/iPods
• These devices do not provide
protection from noise.
• The earphones are not
earmuffs and the music only
adds to background other
noise.
• The music level in the
earphones themselves can
exceed 85 decibels and cause
hearing loss.
41. Monitoring
Environmental Health and Safety
or the Department of Hearing and
Speech can conduct noise
monitoring to determine the level
of noise exposure.
Sound level meter - gives an
instant reading
Sound level dosimeter -
provides an integrated long-
duration (example 6 hour)
reading
EHS maintains record of noise
sampling
Sound Level Meter
Sound Level Dosimeter
42. Audiometric Testing
All University employees
included in the Hearing
Conservation Program must
undergo initial and annual
audiometric testing.
Audiometric testing is required
by TOSHA for any employees
exposed to excessive noise
These tests, which are done by
trained technicians, are used to
gauge hearing loss in affected
employees and will be provided
at no cost to the employees.
The initial test is used as a
baseline and the annual test is
used to determine if hearing
loss has occurred.
43. Purpose of Audiometric Testing
The purpose of Audiometric Testing is
to:
Measure hearing by sending tones
to each ear through headphones.
Show how one’s hearing compares
to normal hearing based on age.
Determine whether hearing is being
conserved.
Alert employee and employer for
noise, age or medical related
hearing loss.
44. Audiometric Testing
Audiometric testing results
can be used to check the
following:
If the hearing protection in
use is adequate,
If there is a change in
noise exposure,
If there is a medical
condition of the ear
unrelated to noise
exposure.
45. When you are first
hired, a baseline test is
taken.
The testing is repeated
every year after that
and compared to the
baseline test result.
If a hearing loss is
detected, you will be
referred to a doctor or
audiologist.
How Does Audiometric Testing Work?
46. Audiometric Testing
Audiometric testing produces
printed audiograms which
show hearing ability at
several pitches or
frequencies.
These frequencies include
those of the human voice.
The second and following
year tests are compared to
the first year tests or
baseline.
If there is hearing loss of 10 decibels or
more in the human voice frequencies, you
will be sent to the doctor or audiologist.
47. An audiogram is a printed chart of the results of the
hearing test. They look similar to the results below.
What is an Audiogram?
Normal hearing Severe hearing loss
48. Training
Training is required for employees who
are exposed to noise at or above 8 hr
TWA of 85 dB.
Topics must include:
Effects of Noise on Hearing
Purpose of Hearing Protectors
Advantages and Disadvantages of
Different Types of Hearing Protectors
Attenuation of Different Types of
Hearing Protectors
Instructions on Selection, Fitting,
Use, and Care of Hearing Protectors
Purpose of Audiometric Testing
49. Employer Responsibility
Employers are responsible for the
following:
Provide occupational noise training.
Provide hearing protection devices.
Demonstrate commitment – wear hearing
protection devices, or PPE, when required.
Enforce the use of PPE.
Keep up to date with PPE selection and use.
Encourage questions and resolve problems.
50. Employee Responsibility
Employees are responsible to:
Understand the need for personal
protective equipment and audiometric
testing.
Wear PPE and seek replacements when
needed.
Encourage co-workers to wear PPE.
Communicate problems to supervisors.
