Hearing safety

Listen at a moderate volume.

Using headphones at a high volume can impair your hearing. This 

•

product can produce sounds in decibel ranges that may cause 

hearing loss for a normal person, even for exposure less than a 

minute. The higher decibel ranges are offered for those that may 

have already experienced some hearing loss.

Sound can be deceiving. Over time your hearing ‘comfort level’ 

•

adapts to higher volumes of sound. So after prolonged listening, 

what sounds ‘normal’ can actually be loud and harmful to your 

hearing. To guard against this, set your volume to a safe level 

before your hearing adapts and leave it there.

To establish a safe volume level:

Set your volume control at a low setting. 

•

Slowly increase the sound until you can hear it comfortably and 

•

clearly, without distortion.

Listen for reasonable periods of time:

Prolonged exposure to sound, even at normally ‘safe’ levels, can 

•

also cause hearing loss.

Be sure to use your equipment reasonably and take appropriate 

•

breaks.

Be sure to observe the following guidelines when using your 

headphones.

Listen at reasonable volumes for reasonable periods of time.

•

Be careful not to adjust the volume as your hearing adapts.

•

Do not turn up the volume so high that you can’t hear what’s 

•

around you.
