Preventing Hearing Damage
Using the receiver, earbuds, headphones, speakerphone, or
earpieces at high volume can result in permanent hearing loss. Be
extremely careful when listening at high decibel levels. Set the volume
to a safe level. If you experience strange sounds in your ears like
ringing or if you hear muffled speech, get your hearing checked. If you
continue to use high volume, your hearing will soon get affected.
Hearing experts offer the following suggestions to protect your
hearing:
• Reduce the time you use the receiver, earbuds, headphones,
speakerphone, or earpieces at high volume.
• Do not increase the volume to block noisy surroundings.
• Reduce the volume if you can’t hear people speaking near you.
