Avoid Hearing Damage
WARNING: Permanent hearing loss may occur if earbuds or headphones are used at
high volume. 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, then stop listening and have your hearing checked. The louder the
volume, the less time required before your hearing can be affected. Hearing experts
suggest that to protect your hearing:
 Limit the amount of time you use earbuds or headphones at high volume
 Avoid turning up the volume to block out noisy surroundings
 Turn the volume down if you can’t hear people speaking to you
