Caution: Avoid Potential Hearing Loss - LG G4 User Manual

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.
Avoid using headphones after exposure to extremely loud noises, such as rock
•
concerts, that might cause temporary hearing loss. Temporary hearing loss might
cause unsafe volumes to sound normal.
Do not listen at any volume that causes you discomfort. If you experience ringing in
•
your ears, hear muffled speech or experience any temporary hearing difficulty after
listening to your portable audio device, discontinue use and consult your doctor.
