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:

Â Limit the amount of time you use earbuds or headphones at high volume

Â Avoid turning up the volume to block out noisy surroundings

Â Turn the volume down if you can’t hear people speaking to you
