Hearing Care Information

Please read this important information before using your Westone True-Fit Earphones.

If, after using your Westone True-Fit Earphones, everything sounds muffled, 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.

	Maximum
dB level	exposure time
85	8 hr.
90	4 hr.
95	2 hr.
100	1 hr.
105	30 min.
110	15 min.
115	7.5 min.

The use of any earphone offers benefits 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 benefits of hearing protection from ambient sound. We want you listening for a lifetime!

Remember, personal hearing protection is your responsibility!
