Since most people with tinnitus also have hearing loss, a pure tone hearing test resulting in an audiogram may help diagnose a cause. An audiogram may also facilitate fitting of a hearing aid in those cases where hearing loss is significant. The pitch of tinnitus is often in the range of the hearing loss.
The prognosis has improved with the recent advancements in digital hearing aid technology, such as directional microphones, open-fit hearing aids, and more advanced algorithms. Hearing aids can mask or cover up the tinnitus, and many with hearing loss and tinnitus find relief by using hearing aids. [136]
This prevents the non-test ear from detecting the test signal presented to the test ear. The threshold of the test ear is measured at the same time as presenting the masking noise to the non-test ear. Thus, thresholds obtained when masking has been applied, provide an accurate representation of the true hearing threshold level of the test ear. [13]
Though the pathophysiology of tinnitus is not known, noise exposure can be a contributing factor, therefore tinnitus can be associated with hearing loss, generated by the cochlea and central nervous system (CNS). High frequency hearing loss causes a high pitched tinnitus and low frequency hearing loss causes a roaring tinnitus. [19]
The individual will deny hearing anything if he/she is a malingerer. An individual with true hearing loss should continue to hear the sound on the better hearing side. Alternatively, this test can be performed more accurately using a two-channel audiometer using pure tone signals. [3]
A pure tone audiometry hearing test is the gold standard for evaluation of hearing loss or disability. [medical citation needed] Other types of hearing tests also generate graphs or tables of results that may be loosely called 'audiograms', but the term is universally used to refer to the result of a pure tone audiometry hearing test.
For an added bonus, the hearing aids offer Bluetooth connectivity for hands-free calls and streaming your favorite music, podcasts and TV shows right to your hearing aid (iPhone 11 or newer ...
A hearing test provides an evaluation of the sensitivity of a person's sense of hearing and is most often performed by an audiologist using an audiometer. An audiometer is used to determine a person's hearing sensitivity at different frequencies. There are other hearing tests as well, e.g., Weber test and Rinne test.
