Phonak Virto B-Titanium User Manual page 44

Should you develop any side effects whilst using the noise
generator such as headaches, nausea, dizziness or heart
palpitations or experience a decrease in auditory function,
you should discontinue use and seek a medical evaluation.
According to OSHA (Occupational Safety & Health
Administration, U.S. Department of Labor) regulations, the
volume of the noise generator can be set to a level which
could lead to permanent hearing damage when used for a
prolonged period of time. Should the noise generator be
set to such a level in your hearing aid, your audiologist
will advise you of the maximum amount of time per day
you should use the noise generator. The noise generator
should never be used at uncomfortable levels.
