External ears and eardrums are examined using a highly illuminated microscope and if necessary cleaned  

Rules out abnormalities of the external ear including the pinna, ear canal, and/or eardrum

  If significant cerumen is revealed, cerumenectomy using otoloop or lavage is completed.  If necessary, patient is referred to ENT.

Tuning Forks

Tuning fork is vibrated and placed at the skull's vertex and around ears and patient asked to respond to questions regarding localization and loudness      


Yields information about the nature of the hearing loss - differentiating conductive versus sensorineural hearing impairment   May affect further testing if hearing loss is conductive in nature.

Tympanometry - objective test of middle ear function

Soft probe is inserted into the ear to measure the mobility and flexibility of the eardrum.  Does not require a patient's active participation.  


Rules out abnormalities involving the middle ear structures, including the eardrum


  If middle ear abnormality is determined, medical referral is indicated.
Acoustic Reflexes - objective test of middle ear & VIIIth nerve function

Same probe for tympanometry is inserted along with an earphone to the opposite ear.  Test measures does  not require a patient's active participation.  


Rules out abnormalities involving the stapedius muscle and/or eighth nerve


  If reflexes are absent or elevated in either ear, further testing is indicated to rule out other potential medical factors.
Sound booth testing
Adult or child is seated in an 8' x 8' sound proof booth per normal audiometric protocol - using foam-insert or standard earphones Testing in a controlled environment guaranties the most accurate and reproducible audiometric evaluation   Extremely reliable hearing test results, repeatable if measured in another laboratory
Speech recognition threshold
Patient repeats simple words like "base-ball" "hot-dog" cup-cake, "ice-cream" etc. Establish patient's general level of audibility   Intensity of speech necessary to understand 50%.  Used to corroborate air conduction thresholds

Air conduction thresholds (adult)

Using earphones, patient pushes a button when they hear, barely hear or think they hear a sound.  Establishes a patient's hearing threshold at various frequencies through outer, middle and inner ears;  expressed as decibels (dB) hearing loss   Basic audiogram.  Determines type and degree of hearing loss.  0-25dB (normal); 25-40dB (mild loss); 40-70dB (moderate loss); 70-90dB (severe loss); 90dB or worse (profound loss).

Air conduction (pediatric)

For children age two to five, "play audiometry" is used to elicit responses.  In play audiometry, children learn to pair hearing tones with play a game.     Play audiometry yields reliable threshold responses.  Mostly used to "screen" hearing ability in cases where a child's speech/language development is delayed  

PASS SCREENING - no hearing loss

FAILED SCREENING - further testing warranted

Word recognition (speech discrimination)
Patient repeats a list of one syllable words (without the aid of context) like "carve" "bathe" "ace" etc. Yields a general measure word clarity and expressed as a percentage.       90-100%->excellent; 80-90%-> fair; 70-80%->poor; <60%0> profoundly impaired.
Hearing in noise testing
Patient repeats short sentences with competing background noise interference Determine patient's level of difficulty while in the presence of background noise   Affects decisions regarding effective hearing aid management
Bone conduction*
Using a bone oscillator positioned on the mastoid process patient pushes a button when they hear a sound.   Bypasses the outer and middle ears, and establishes thresholds exclusively in the inner ear.    The main purpose is to rule out "conductive" hearing loss.
Acoustic reflexes*
A probe is inserted into the ear to measure the presence of absence of the stapedius muscle  The stapedius muscle normally contracts in response to a loud sound.  The test rules out various ear abnormalities.       

PRESENT - normal

ELEVATED - suspicious of retro-cochlear involvement

ABSENT - abnormal

Comfortable loudness
Patient listens to sounds to establish point of most comfortable loudness (MCL) and loudness discomfort level (LDL) If hearing aids are necessary, this testing assists with setting  gain and maximum output limits in the hearing aid circuitry.   Affects decisions regarding effective hearing aid management

* Conducted when necessary
