Please read this important information before using your
Westone True-Fit Earphones.
If, after using your Westone True-Fit Earphones, everything
sounds mued, or if you hear ringing or buzzing, your
ears are trying to give you a warning! These symptoms are
normally associated with a condition known as Temporary
Threshold Shift and are an indication of conditions that could
lead to permanent hearing loss.
While no two individuals’ hearing sensitivity is exactly the
same, there are established safety guidelines for sound
levels versus time of exposure. The chart to the right is based
on OSHA’s (Occupational Safety and Health Administration)
exposure information for industry. Remember that these
guidelines are based on average hearing sensitivity – your
sensitivity may be above or below these levels.
The use of any earphone oers benets and risks. Westone True-Fit Earphones can lower
ambient sound levels approximately 25 dB when properly worn. However, the performance
capabilities of the earphones can allow the user to negate the benets of hearing protection
from ambient sound. We want you listening for a lifetime!
Remember, personal hearing protection is your responsibility!
