    1. 1. By, Dr. Shamanthakamani Narendran, MD, PhD Hearing Loss Prevalence Hearing loss: • Is one of the most prevalent chronic conditions affecting more than nine million over the age of 65 and 10 million age 45 to 64. • Approximately three out of five older with hearing loss and six out of seven middle-aged with hearing loss do not use hearing aids. Only 1 in 5 use amplification

    9. 9. By, Dr. Shamanthakamani Narendran, MD, PhD Methods Of Screening  Acustic Emission Testing.  Detection of emission from outer hair cells of chochlea.  Non Invasive
    10. 10. By, Dr. Shamanthakamani Narendran, MD, PhD  Auditory Brain Stem Response Testing  Measurement of Electric response from cochlea till cortex
    11. 11. By, Dr. Shamanthakamani Narendran, MD, PhD CONDUCTIVE  Most conductive hearing loss, which occurs in the outer or middle ear, can be cured - either by medical treatment or through surgery. Conductive hearing loss is often temporary, e.g. when due to earwax. Stapes replacement surgery is an option in certain conditions.

    29. 29. By, Dr. Shamanthakamani Narendran, MD, PhD BLUFFING  . There may be times when despite the best efforts of both parties to a conversation, the person with hearing loss just doesn’t understand what is being said. This will be more likely to happen when conditions are less than idea. It’s happens to me often (haven’t understood even after repeated requests); how about you-how do you handle this?
    30. 30. By, Dr. Shamanthakamani Narendran, MD, PhD Planning  Planning ahead is very important for people with hearing loss.  For an example- lets go to McDonalds and practice on how to mentally prepare yourself for ordering your happy meal
    31. 31. By, Dr. Shamanthakamani Narendran, MD, PhD COPING WITH HEARING LOSS  Hear we GO… Some practical suggestions that might help you hear & understand better. Let’s discuss
    32. 32. By, Dr. Shamanthakamani Narendran, MD, PhD AT THE RESTAURANT  Arrive early- beat the crowd (and the noise). Avoid kids and parties. Ask for TV to be turned down.  Sit in “quiet corner”- back to wall. Lip-read where possible. Check lighting.  Peruse menu beforehand; if waiter recites ‘specials of the day’ ask to read his/her sheet or repeat just to you  Seating: Face inside; not out the window (glare  )
    33. 33. By, Dr. Shamanthakamani Narendran, MD, PhD COPING @ THE AIRPORT  “Flight 309 is Now Boarding at Gate 23”  Would you hear this announcement? DISCUSSION: Tips for better hearing at the airport
    34. 34. By, Dr. Shamanthakamani Narendran, MD, PhD COPING WHILE DRIVING  Use ALDs  Defensive driving (mirrors)  Talk to me when at Stop Sign or Traffic Light  Turn off radio  Keep a/c or heater on low / roll up windows if possible ANY SUGGESTIONS OR INPUT ON HOW YOU COPE WHEN YOU ARE THE HARD OF HEARING DRIVER?

    37. 37. By, Dr. Shamanthakamani Narendran, MD, PhD A DISCUSSION OF ASSISTIVE DEVICES  A discussion of devices and instruments to supplement the use of hearing aids. THESE ARE CALLED ALDs –short for ASSISTIVE LISTENING DEVICES
    38. 38. By, Dr. Shamanthakamani Narendran, MD, PhD Why Use Assistive Listening Devices?  Hearing aids alone doHearing aids alone do not work well in thesenot work well in these situations: ALDs help!situations: ALDs help! Listening to someone at a distance Listening in a noisy environment Listening in a room with reverberation (echoing)
    39. 39. By, Dr. Shamanthakamani Narendran, MD, PhD Watching TV: Choice of Infra red or FM systems  IR Uses infrared light to transmit the TV signal.  FM sends out a FM radio signal  Both types of transmitters connects to your TV. Use the receiver to hear the TV sound directly in your ears.  (Rooms may be looped with wire, connected to an amplifier and T Coil activated) headphones Ear bud or loop
    40. 40. By, Dr. Shamanthakamani Narendran, MD, PhD Alarm Clocks  Portable Clock  Looks like a travel alarm  Vibrates and/or sounds alarm  Clock System  Adjust loudness and frequency  Connect to lamp  Connect to bed shaker
    41. 41. By, Dr. Shamanthakamani Narendran, MD, PhD Doorbell  Doorbell Signalers Connected to Lamp  Wireless – lamp plugs into receiver  Simple wiring  Knock Sensor  Self-contained  Mounted on door with flashing light  Flashing Light/Chime Pager  Use transmitter and receiver  Flashing light and/or chime

Children, older adults and people with hearing loss can sleep through traditional smoke alarms. Lifetone gives you extra bedside protection. PROTECT YOURSELF The Lifetone HL™ Bedside Fire Alarm and Clock's 520 Hz square-wave sound pattern is proven to wake significantly more sleepers — including older adults, people with hearing loss and children.
