Important Hearing Care Information
If, after using your Westone CR1 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 following chart is based on OSHA’s
(Occupational Health and Safety 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 CR1 Earphones can
lower ambient sound levels approximately 25dB 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!
