Responsible Listening
Avoid potential hearing loss. Damage to hearing occurs when a person is exposed to
loud sounds over time. The risk of hearing loss increases as sound is played louder and
for longer durations. Prolonged exposure to loud sounds (including music) is the most
common cause of preventable hearing loss. Some scientific research suggests that
using portable audio devices, such as portable music players and cellular telephones, at
high volume settings for long durations may lead to permanent noise–induced hearing
loss. This includes the use of headphones (including headsets, earbuds and Bluetooth
or other wireless devices). Exposure to very loud sounds has also been associated in
some studies with tinnitus (a ringing in the ear), hypersensitivity to sound and distorted
hearing. Individual susceptibility to noise–induced hearing loss and potential hearing
problem varies. Additionally, the amount of sound produced by a portable audio device
varies depending on the nature of the sound, the device settings and the headphones
that are used. As a result, there is no single volume setting that is appropriate for
everyone or for every combination of sound, settings and equipment.
You should follow some commonsense recommendations when using any portable
audio device:
• Set the volume in a quiet environment and select the lowest volume at which you can
hear adequately.
• When using headphones, turn the volume down if you cannot hear the people speaking
near you or if the person sitting next to you can hear what you are listening to.
