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.
and take appropriate breaks.
