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.
