9.6 Prescription use of a Tinnitus Sound Generator (TSG) hearing aid
The TSG module should be used as prescribed by your doctor, audiologist or hearing care professional. In
order to avoid permanent hearing damages, the maximum daily usage depends on the level of the gener-
ated sound.
Should you develop any side effects from using the sound generator, such as dizziness, nausea, head-
aches, perceived decrease in auditory function or increase in tinnitus perception, you should discontinue
use of the sound generator and seek medical evaluation.
The target population is primarily the adult population over 18 years of age. This product may also be used
with children 5 years of age or older. However, children and physically or mentally challenged users will
require training by a doctor, audiologist, hearing care professional or the guardian for the insertion and
removal of the hearing aid containing the TSG module.
9.7 Important notice for prospective sound generator users
A tinnitus masker is an electronic device intended to generate noise of sufficient intensity and bandwidth to
mask internal noises. It is also used as an aid in hearing external noises and speech.
Good health practice requires that a person with a tinnitus condition have a medical evaluation by a licensed
physician (preferably a physician who specializes in diseases of the ear) before using a sound generator.
Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists, otolo-
gists or otorhinolaryngologists.
The purpose of medical evaluation is to assure that all medically treatable conditions that may affect tinnitus
are identified and treated before the sound generator instrument is used.
The sound generator instrument is a tool to generate sounds to be used with appropriate counselling and/
or in a tinnitus management programme to relieve patients suffering from tinnitus.
