(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
