Preventing Hearing Loss

[Feature Article] Jan Voetmann, chair of the tutorial Hearing Loss—Causes, Preventative Measures, and Effects on Sound Professionals and the Audience, presented at the AES 120th Convention in Paris in May, introduced the event by explaining that the official limit for occupational noise is also used for evaluating the effects of listening to music. A sound level of 85 dBA for 8 hours of the day leads to an equivalent of around 100 dBA for a quarter of an hour, which is easily reached in leisure time by many people either in the home and yard, in clubs and discos, and at work. (For further information about equivalent noise levels see Noise Exposure on next page.) Short intervals with very high peak sound levels can still lie within the noise dose guidelines, even though they can be harmful. Voetmann said that it is difficult to find young people with normal hearing levels, based on informal data gathered at a university in Munich that showed common hearing losses consistent with listening to music at high levels. Gunshots, as experienced by hunters or soldiers, can reach 160 dB for a short period, and woodwind players in an orchestra can experience 128 dBC. If you go to a rock concert and stand in front of the loudspeakers you can experience 129 dBC. For an online sound demo, go to, where you can adjust a noise meter to hear the different sounds and sound intensities of everyday objects, courtesy the U.S. National Institute of Occupational Safety and Health.

-Why do we hear a "whistle" while using ear plugs in a quiet place? For example: being in bed at night with ear plugs, produce a "whistle"?
-What is it the correct form of usin ear plugs, "all the way in" or "half way in" of our ears?
Hopefully I'm clear enough to formulate my questions, and if there is not an answer, I'm here to help out to find it out.
Kind regards.

The ringing of ears in silence is called tinnitus. You can read more about it for example in this paper published in the AES 58th International Conference on Music Induced Hearing Disorders in 2015:
