Tinnitus Testing

Because tinnitus is so often caused by hearing loss, most audiologists will begin with a comprehensive audiological evaluation that measures the patient’s overall hearing health.


General Hearing Tests Include:

Speech Recognition Test

A subjective measure of how well the patient hears and can repeat certain words. Sometimes called speech audiometry.


Acoustic Reflex Testing

An objective test that measures the contraction of the middle ear muscles in response to loud sounds.

Pure Tone Audiogram

A subjective test that measures the patient’s hearing across multiple frequencies (measured in Hertz) and volumes (measured in decibels).


Otoacoustic Emissions Testing

The use of very sensitive microphones to objectively measure the movement of hair cells within the middle ear.

Tympanogram

An objective test that measures the functioning of the middle ear, specifically the mobility of the tympanic membrane and the conduction bones.



It is important to determine the specific gaps in a tinnitus patient’s hearing, because this often correlates to the nature and quality of their particular tinnitus. (For instance, high-frequency hearing loss often corresponds with high-frequency tinnitus.) Moreover, specific hearing markers may inform different potential treatment options for tinnitus.

When evaluating tinnitus cases, hearing health professionals use a supplemental set of tests. While there is currently no way to objectively test for tinnitus, there are several protocols to measure the patient’s subjective perception of tinnitus sound, pitch, and volume.


Specifically, The Doctor May Test:

Tinnitus Pitch and Loudness Matching:

The presentation of common tinnitus sounds back to patients, to help them identify their specific perception of tinnitus. The audiologist may adjust the pitch or loudness and layer multiple sounds to create an exact audio recreation of the the tinnitus. Sound matching provides an important baseline for subsequent tinnitus management therapies, which are often customized for each patient.

Minimum Masking Level

The volume at which an external narrowband noise masks (or covers) the perception of tinnitus. Determining the minimum masking level provides an approximate measure of how loud a patient perceives his/her tinnitus and can be used in subsequent tinnitus masking and sound therapies.

Loudness Discomfort Level

The volume at which external sound becomes uncomfortable or painful for a tinnitus patient. This measurement informs the feasibility of sound therapy, masking, and hearing aids as potential tinnitus treatments. Determining loudness discomfort levels is particularly important for patients with hyperacusis, an extreme sensitivity to noise.

Residual Inhibition

A temporary quieting of tinnitus that can happen after listening to particular types of sound. A sound that can cause this to happen is called here a quieting sound or a trigger sound. Although the effect of a single quieting sound is temporary for many people tinnitus can be kept reduced for much longer periods by simply keeping a repeating form of the quieting sound playing. Determining if there is an inhibition response, even partial, can inform potential rehabilitation options.
A hearing health professional may administer additional tests, depending on the patient’s specific symptoms, medical history, and/or attenuating risk factors. In some extreme situations, an MRI (magnetic resonance imaging) may be appropriate for someone experiencing tinnitus; however, MRIs should only be administered in cases when independent clinical evaluation suggests specific (and rare) tinnitus etiologies.

Tests To Measure Tinnitus Burden

Tinnitus doesn’t just impact hearing; it can cause a cascade of negative mental, cognitive, and physical consequences. The difference between tinnitus being a minor or major issue of the patients’ is less often related to how loud tinnitus is, but rather how the tinnitus impacts other facets of patients’ lives.
As such, clinicians and researchers have developed inventory tests to measure the subjective burden a patient experiences because of tinnitus. There are several varieties of these tests, but they all operate by quantifying the patient’s personal reaction to tinnitus:


Tinnitus Handicap Inventory

Tinnitus Functional Index

Tinnitus Severity Index

Visual Analog Scales
