Audiological Glossary of Terms

How We Hear

    Outer Ear

    The outer ear consists of the ear canal and eardrum.  Sound travels down the ear canal, striking the eardrum and causing it to move.

    Middle Ear

    The middle ear is the space behind the eardrum that contain the 3 small bones called ossicles that are connected to the eardrum and the inner ear.  Vibration from the eardrum causes the ossicles to vibrate which transfer to the inner ear.

    Inner Ear

    Movement of the fluid in the inner ear (cochlear) causes the hair cells to move.  Movement of the hair cells sends electrical signal to auditory nerve and up to the brain.

What is Hearing Loss?

Types of Hearing Loss

    Conductive Hearing Loss

    Conductive hearing loss occurs when sound is not conducted efficiently through the outer ear canal to the eardrum and the ossicles of the middle ear.

    Sensorineural Hearing Loss

    Sensorineural hearing loss occurs when there is damage to the cochlear or the nerve pathways from the inner ear to the brain.  This is the most common type of permanent hearing loss.

    Mixed Hearing Loss

    Mixed hearing loss is a combination of conductive and sensorineural hearing loss.  This occurs when there is damage to both the outer or middle ear and the inner ear.

Degree of Hearing Loss

    Mild Hearing Loss

    26 to 40 dB HL loss

    Difficulty hearing soft speech and conversation, especially in noisy environments.

    Moderate Hearing Loss

    41 to 55 dB HL loss

    Difficulties understanding speech at average loudness level, especially in the presence of background noise.

    Moderately Severe Hearing Loss

    56 to 70 dB HL loss

    Ability to understand speech is severely affected.  Difficulty with group conversation even in quiet environment.

    Severe Hearing Loss

    71 to 90 dB HL loss

    Regular speech is inaudible. Difficulties even with loud speech.

    Profound Hearing Loss

    91+ dB HL loss

    Even amplified speech is difficult to understand or even inaudible.

Causes of Hearing Loss

    Otitis Media

    Infection of the middle ear, very often accompanies by a common cold, the flu, or other types of respiratory infections.

    Impacted Earwax

    Some people are naturally producing more ear wax (cerumen) and are more susceptible to developing impacted earwax.  Earwax impaction can also occurs when wax get pushed deep into the ear canal with Q-tips.


    Otosclerosis is a disease of the bones of the middle and inner ear.  The condition is caused by abnormal bone remodelling or growth in the middle ear.

    Perforated Eardrum

    Perforated eardrum or ruptured eardrum can be caused by ear infection, extremely loud sounds, or Q-tips get pushed too deep into the ear canal to the ear drum.

    Meniere’s Disease

    Meniere’s disease is a disorder that affects the inner ear.  This disorder can cause vertigo, hearing loss, and tinnitus.  It usually affects only one ear.

    Noise Induced Hearing Loss

    Noise induced hearing loss is caused by extremely loud bursts of sound that can damage the middle and inner ear.  It can also be caused by loud sounds over time as part of a person’s profession or hobby.  Loud noise exposure can also cause tinnitus.



What is Tinnitus?

Tinnitus, or ringing in the ears, is the sensation of hearing ringing, buzzing, hissing, chirping, whistling, or other sounds.  The noise can be intermittent or continuous, and can vary in loudness.  Tinnitus is usually accompanied by hearing loss. 

How is Tinnitus Treated?

Hearing Aids

If you have a hearing loss, there is a good chance that a hearing aid will both relieve your tinnitus and help you hear better.

Tinnitus Masker

Tinnitus masker looks like hearing aid but instead of amplifying sounds, it provides sounds that can masks or covers up the tinnitus.


Audiologic Evaluation

Immittance Testing


    Evaluates the integrity of the middle
    ear system (tympanic membrane and

    Acoustic Reflex Threshold

    Evaluates the integrity of the acoustic
    neural pathway(Stapedius muscle dominant).

Pure-tone Testing

    The purpose of the test is to find the faintest tone the patient can hear.

Speech Testing

    Speech Reception Threshold (SRT)

    Establishes the intensity at which a patient can repeat
    familiar words correctly 50% of the time.

    Word Recognition Score (WRS)

    Establishes the patient’s ability to
    recognize a word correctly when it is
    presented at an intensity so that the
    speech frequencies are audible to the

Otoacoustic Emissions (OAEs)

    OAEs are used to differentiate hearing loss due to outer hair cells dysfunction from other types of hearing loss in all populations (infants, adults, and the elderly).
