The use of an externally produced sound to either cover up or in some way inhibit or alter production of tinnitus can offer relief for some. There are six main methods of acoustic stimulation.
Unfortunately, some tinnitus sufferers find that masking noise may merely be a substitute of one annoying sound for another. It is thus better to try to relegate the annoyance of tinnitus to the background of one’s consciousness through habituation or retraining methods.
Many patients find that music, particularly classical passages that don’t contain wide variations in loudness (amplitude) can be both soothing to the limbic system (the emotional processor in the brain that is commonly negatively linked to a patient’s reaction to tinnitus) and stimulating to the auditory cortex. If a hearing loss is present, it may be necessary to alter the spectrum of the music so that the cortical neurons receive appropriate stimulation.
The use of hearing aids and a combination of hearing aids and maskers are often effective ways to minimize tinnitus. While it is not clear whether hearing aids help by amplifying background sounds that can mask out the tinnitus or by actually altering the production of tinnitus, most hearing aid wearers report at least some reduction in their tinnitus. This may be due to the reduction in contrast between tinnitus and silence, or because of the new stimulation provided to the brain.
