compatible receivers, headphones, speakerphones or earpieces with
your device. Turn on the audio and check the volume before inserting
anything in your ear. You can adapt over time to a higher volume of
sound that may sound normal but can be damaging to your hearing. If
you experience ringing in your ears or muffled speech, stop listening
and have your hearing checked. The louder the volume, the less time
is required before your hearing could be affected. Hearing experts
suggest that to protect your hearing:
Limit the amount of time you use the receiver, headphones,
speakerphone, or earpieces at high volume.
Avoid turning up the volume to block out noisy surroundings.
Turn the volume down if you can’t hear people speaking near you.
