THE FOLLOWING NOISE CAN BE HARMFUL UNDER CONSTANT EXPOSURE
PERMANENT LOSS OF HEARING
THRESHOLD OF PAIN
• Over time your hearing will adapt continuous loud sounds and will give the
impression that the volume has in fact been reduced. What seems normal to you
may in fact be harmful. To guard against this BEFORE YOUR HEARING
ADAPTS set the volume at a low level.
• Slowly increase the level until you can hear comfortably and clearly and
without distortion.
• Damage to your hearing is accumulative and is irreversible.
• Any ringing or discomfort in the ears indicates that the volume is too loud.
Once you have established a comfortable listening level, DO NOT INCREASE
THE SOUND LEVEL FURTHER.
The following list of typical sound levels may assist you in recognizing just how
loud you have set the volume level.
