The document discusses the dangers of listening to music or using earpieces at high volumes for extended periods of time, as it can cause permanent hearing damage. It then focuses on the additional risks of using sensitive earpieces meant for devices like MP3 players with high-powered devices like walkie talkies, as the earpieces cannot handle the power and sound becomes distorted, risking instant hearing damage. The document recommends using an AdaptEar device when using earpieces with high-powered sources like walkie talkies, as it prevents acoustic shock and limits damaging signals to protect the user's hearing.

2. Protecting Your Hearing Most of us use earpieces with MP3 players to listen to music. It is recognised that listening to music at high levels for long periods of time can permanently damage hearing There are high profile campaigns and articles to make us aware of the dangers: RNID – Don’t lose the Music Noise Abatement Society – Love Your Ears Deafness Research Daily Telegraph, Daily Mail, Sunday Mail etc

3. Work and Play That may be OK in our private lives, but what about those who use earpieces at work?

4. A dangerous combination Most earpieces are very sensitive as they are designed to work with low out-put sources such as MP3 players or mobile phones. Private Mobile Radios (PMR) or Walkie Talkies are high out-put sources which are designed to work with matched headphones.

5. A dangerous combination

6. A dangerous combination Using earpieces with a PMR or walkie talkie is potentially very damaging to hearing unless limiters or AdaptEar ® are used. Earpieces can’t handle the power and the sound is rapidly distorted. Some earpieces used with PMRs can produce sound levels that will cause instant permanent hearing damage.

7. A dangerous combination Not only is the combination potentially dangerous the volume level is difficult to control. Small increases in volume control on the PMR create big increases in level in the earpieces.

8. Safety If earpieces are used with a PMR or similar high power source AdaptEar ® should be used

9. Using AdaptEar ® Before use, AdaptEar ® sensitivity should be set to match the earpieces performance The MiniDIN plug is inserted into the MiniDIN socket on AdaptEar ® The 3.5 mm jack plugs into the 3.5 mm listen only socket on the PMR Earpieces are plugged into the “Phones” socket of the AdaptEar ® The user is now protected and ready to go

10. AdaptEar ® at work

11. AdaptEar ® The increase in volume in the ear becomes proportional to the volume control on the PMR Acoustic shock and high volumes are prevented The more damaging highly compressed signals are limited sooner than the less damaging human voice Indicates that the safe limit is being reached and user is being protected Alerts user to turn down the volume

12. AdaptEar ® Optional interchangeable adapter cables enable use with a wide range of PMRs, television cameras and other communication sources. User adjustable sensitivity allows the use of different earpieces in different circumstances Optional fist Mic provides reverse talk back Auxiliary input enables the monitoring of two sources simultaneously Two year warranty, if it breaks return and we will replace it
