How to Avoid Undesirable Side Effects

During the development of the hearing instrument analyzer, Audioscan performed a rigorous Risk Assessment to

identify any undesirable side effects that a user could be exposed to during the use of the Verifit, and

incorporated numerous risk reduction design elements into the Verifit to minimize the risk to users and patients.

Following are the actions which a user should take to ensure that these risk control measures continue to be

effective

Loud Sounds

The Verifit is designed to produce sound pressure levels as high as 85 dB at the probe reference

microphone. Exposure to these levels for more than 7 hours can produce hearing damage. When such levels are

amplified by a hearing instrument, the level in the ear canal will be determined by the settings of the hearing

instrument but may reach levels that can produce hearing damage in less than 30 seconds. To avoid this

possibility,

a) Hearing instruments should be adjusted to limit sound pressure levels to safe levels

b) The maximum TM SPL setting (see Max TM SPL Setup) should be used to terminate tests if an unsafe level

is detected in the ear canal

c) Test levels should be limited to 70 dB SPL except when necessary to verify the limiting levels of the hearing

instrument, in which case, the test should not last longer than 15 seconds

d) Be aware of the test signal and patient reaction during a test and be prepared to respond to any sign of

discomfort by reducing the SPL setting, switching off the equipment or the hearing instrument, or removing the

patient from the area.
