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 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 health care provider.
