Caution: Avoid potential hearing loss
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 sound 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 other potential
hearing problems varies.
The amount of sound produced by a portable audio device
varies depending on the nature of the sound, the device, the
device settings and the headphones. 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.
• Do not turn the volume up to block out noisy surroundings.
If you choose to listen to your portable device in a noisy
environment, use noise-cancelling headphones to block out
background environmental noise.
• Limit the amount of time you listen. As the volume
increases, less time is required before your hearing could be
affected.
