Hearing Loss | Clermont FL Hearing Loss | Clermont FL Presentation Transcript

  • HEARING AID 101 Session 1 www.fixmyhearing.com [email_address] Welcome to…
  • Introductions…
    • Any new hearing aid users??
    • Reasons for getting hearing aids??
  • Outline for Session 1:
    • HOW WE HEAR
    • REALISTIC EXPECTATIONS OF HEARING AIDS
    • INTERPRETING HEARING LOSS
    • ADJUSTING TO HEARING AIDS
    • DO’s/DON’Ts OF HEARING AIDS & BATTERIES
    • TROUBLESHOOTING TIPS
  • HOW WE HEAR…
  • How we Hear…
    • We have 3 major parts to the ear that work together to send sound to the brain where it is interpreted
  • Outer Ear
    • Job is to collect sound waves and funnel them along the ear canal to the eardrum
  • Middle Ear
    • When the sound waves hit the eardrum, they cause the eardrum to vibrate
    • The vibration causes the 3 bones of the middle ear to move
    • The middle ear space is a sealed, air-filled cavity. The Eustachian Tube connects the middle ear to the back of the nose. This tube equalizes pressure changes to the outside air.
  • Inner Ear
    • The movement of the 3 middle ear bones sets the fluid of the inner ear into motion
    • Fluid movement shears thousands of microscopic hair cells
    • Shearing of a hair cell stimulates the auditory nerve
    • The auditory nerve sends
    • an impulse to the brain
    • where the signal is
    • interpreted
    • The inner ear also houses the balance organs!
  • In a nutshell… 1. Fluid movement shears hair cells… 2. The sheared hair cells activate the auditory nerve – telling it to send a signal… 3. The signal reaches the auditory center in the brain where it is interpreted! Cochlea Auditory Nerve Brain
  • A view from the front…
  • How DOES hearing loss occur?
    • A hearing loss can result from disruption of normal function ANYWHERE along the auditory system
  • 3 types of hearing loss can occur…
    • CONDUCTIVE HEARING LOSS : A hearing loss resulting from disorders of the OUTER &/or MIDDLE EARS
      • Sound is prevented from entering a normal functioning inner ear
  • Conductive Hearing Loss
    • What causes this “blockage” of sound?
    • Middle ear infection
    • Fluid in the middle ear (with no infection)
    • Ruptured eardrum
    • Unhinging of the middle ear bones
    • Stiffening of the middle ear bones (otosclerosis)
    • Tumor in the middle ear space
    • Wax build-up
  • Some examples of conductive losses…
    • Can usually be treated medically or surgically
  • Types of loss (continued)…
    • 2. SENSORINEURAL HEARING LOSS : A hearing loss resulting from disorders or damage to the inner ear (cochlea) &/or the auditory nerve. Commonly referred to as “nerve loss”.
  • What causes a sensorineural hearing loss??
    • Noise exposure
    • Advancing Age
    • Hereditary
    • Ototoxic medications
    • Syndromes/Disorders
    • Infections
    • Head Trauma
    • Tumor on auditory nerve
    • … or a COMBINATION of the above
  • Characteristics of Sensorineural Hearing Loss:
    • Usually permanent
    • Can continue to deteriorate
    • Usually NOT treatable by medication/surgery
    • Hearing aids are the solution!
  •  
  • Types of loss (continued)…
    • 3. MIXED HEARING LOSS : A hearing loss that consists of BOTH a conductive and a sensorineural component
    • Example: A sensorineural hearing loss from noise exposure + a conductive hearing loss from a perforated eardrum = MIXED HEARING LOSS
  • “ I can hear but I can’t understand ”
    • If the problem is with DETECTING sounds, making the sounds louder will make them clear… this is true for the person with a Conductive hearing loss (remember, they have a normal inner ear)
    • LOUDNESS
    • LOUDNESS
    • LOUDNESS
    • LOUDNESS
    • LOUDNESS
  • “ I can hear but I can’t understand ”
    • If the problem is with understanding, however, then making sounds louder will NOT provide normal, clear speech. This is the case with Sensorineural hearing loss .
    • CLEARNESS
    • CLEARNESS
    • CLEARNESS
    • CLEARNESS
  • WHY?
    • Damage to the inner ear/nerve (i.e. loss of hair cells) creates a DISTORTED signal that is sent to the brain.
    • This is why individuals with sensorineural hearing loss need to know that hearing aids do not restore normal hearing
    • Having REALISTIC EXPECTATIONS of hearing aids is important!
  • Realistic Expectations…
    • Your voice & the voices of others may sound different
    • Background noise will inevitably get amplified in addition to speech, therefore speech may be difficult to understand in noise
    • You may have difficulty understanding speech (in general) depending on the severity of your hearing loss, the speaker, and the environment
  • Realistic Expectations …(continued)
    • It will still be difficult to understand people talking from another room
    • Hearing aids are less helpful in rooms with hard floors & walls & no carpet or drapes
    • Hearing aids should be a comfortable fit
    • No feedback at a comfortable volume setting
    • Hearing aids should make soft sounds audible , normal sounds comfortable , and loud sounds tolerable
    • Even people with normal hearing find many listening situations difficult!
  • Do you know how to read your hearing loss??
    • Sound is made up of pitch & loudness
    • Unwanted sound is referred to as “NOISE”
  • A moderate high-frequency sensorineural hearing loss… NORMAL HEARING = RIGHT EAR = LEFT EAR
  • Degrees of Hearing Loss:
    • Mild loss : Difficulty with faint speech & speech in “less than ideal” situations
    • Moderate loss : Frequent difficulty with normal speech (even in “ideal” situations”); repetition is often necessary; listening is a strain
    • Severe loss : May hear loud voice approximately 1 ft. from ear; may identify environmental sounds; may distinguish vowels of speech
    • Profound loss : Usually cannot understand amplified speech; hearing is not typically the primary mode of communication

  • Adjusting to your Hearing Aids…
    • Quiet living room. One person talks about familiar things at different places in the room.
    • Go to kitchen. Run the water.
    • Radio/TV in a quiet room. Have a person with normal hearing adjust the volume. Begin with the news.
    • Wear aids at quiet dinner table.
    • Conversation in quiet room with 2…3…4 other people.
    • Outside (quiet place). Listen to wind noise.
    • Walk along street (quiet neighborhood).
    • Church, lectures, play. Sit close to speakers first. Later, try listening from a distance.
    • Driving. Listen to background noises. Open the window.
    • Shopping trip.
    • Party or room where several people are talking.
    Easier Harder
  • Above all…
    • BE PATIENT!
    • Through time, noise and meaning will begin to sort themselves out
    • The more often you wear your hearing aids, the quicker this “sorting out” process will occur
    • THE BRAIN HAS TO HEAR WHAT THE BRAIN DOESN’T WANT TO HEAR IN ORDER TO KNOW IT DOESN’T WANT TO HEAR IT!!
  • Care & Maintenance of your Hearing Aids:
    • DO:
    • Clean your hearing aids everyday using clean, dry hands!
    • Store your hearing aids in a cool, dry place!
    • Remove your hearing aids when heavily perspiring from exercise/work!
    • Open your battery doors when not in use!
    • Keep your hearing aids away from pets & small children!
  • Care & Maintenance of your Hearing Aids:
    • DON’T:
    • Take your hearing aids out/change the battery while standing on a hard surface (i.e. tile floor)!
    • Bathe, shower, swim with hearing aids in!
    • Use hairspray or a hairdryer with the hearing aids in!
    • Wear your hearing aid if it is causing soreness!
    • Wear hearing aids around loud noises/heavy machinery. Ear protection should be worn!
  • Care & Maintenance of your Batteries:
    • DO:
    • Carry spare batteries!
    • Keep tabs ON batteries until ready to use!
    • Keep track of batteries by placing the tab on the calendar day you changed it!
    • Throw away old batteries after use!
    • Use fresh, new batteries each time!
    • Check medications before swallowing…batteries have been mistaken for pills!
    • Keep away from pets!
  • Care & Maintenance of your Batteries:
    • DON’T:
    • Force the battery compartment shut – check the direction of the battery!
    • Carry loose batteries in a pocket/purse!
    • Change batteries in front of small children or those of mental incapacity!
    Batteries are toxic if accidentally swallowed: Contact the National Button Battery Hotline at (202) 625- 3333 for accidental ingestion.
  • Troubleshooting Tips:
