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.
You should use caution or temporarily discontinue use in potentially
•
hazardous situations. Do not use headphones while operating a
motorized vehicle, cycling, skateboarding, etc.; it may create a traffi c
hazard and is illegal in many areas.
Caution
Use of controls or adjustments or performance of procedures other than herein •
may result in hazardous radiation exposure or other unsafe operation.
