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.
