Please read this important information before using your
Westone UM monitors.
If, after using your UM monitors, everything sounds mued,
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 following chart is based
on OSHA’s (Occupational Health and Saftey 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 monitors oers benets and risks. Westone UM monitors can lower ambient
sound levels approximately 25dB when properly worn. However, the performance capabilities
of the monitors can allow the user to negate the benets of hearing protection from ambient
sound. We want you listening for a lifetime!
Remember, personal hearing protection is your responsibility!
