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
hearing loss. This includes the use of headphones (including headsets, ear
buds and Bluetooth®, or other wireless devices). Exposure to very loud sound
has also been associated in some studies with tinnitus (ringing in the ear),
hypersensitivity to sound, and distorted hearing. 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. Hence, individual
susceptibility to noise-induced hearing loss and other hearing problems can
vary. Please follow these important guidelines for hearing loss prevention:
1.
Set the phone's volume in a quiet environment and select the lowest
volume for which you can hear clearly.
2.
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.
3.
Do not turn the volume up to block out noisy surroundings. If you choose
to listen to your portable device in a noisy environment, consider using
noise-cancelling headphones to block out background noise.
4.
As the volume increases, less time is required before your hearing could
be affected, so consider limiting your listening time.
5.
Avoid using headphones after exposure to extremely loud noises (e.g.:
live concerts) that might cause temporary hearing loss which, in turn,
might cause unsafe volume levels to sound like normal levels.
6.
Do not listen at any volume that causes you discomfort. If you experience
