  2. Real ear measurement - Wikipedia

    en.wikipedia.org/wiki/Real_ear_measurement

    Real ear measurement is the measurement of sound pressure level in a patient's ear canal developed when a hearing aid is worn. It is measured with the use of a silicone probe tube inserted in the canal connected to a microphone outside the ear and is done to verify that the hearing aid is providing suitable amplification for a patient's hearing loss.

  3. Tympanometry - Wikipedia

    en.wikipedia.org/wiki/Tympanometry

    Tympanometry is an objective test of middle-ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear. It is not a measure of eardrum or middle ear mobility. It is an acoustic measure, measured by a microphone, as part of the ear canal probe, inserted into the ear canal.

  4. Pure-tone audiometry - Wikipedia

    en.wikipedia.org/wiki/Pure-tone_audiometry

    Pure-tone audiometry is a subjective, behavioural measurement of a hearing threshold, as it relies on patient responses to pure tone stimuli. [3] Therefore, pure-tone audiometry is only used on adults and children old enough to cooperate with the test procedure.

  6. Audiometry - Wikipedia

    en.wikipedia.org/wiki/Audiometry

    Acoustic immittance audiometry - Immittance audiometry is an objective technique which evaluates middle ear function by three procedures: static immittance, tympanometry, and the measurement of acoustic reflex threshold sensitivity. Immittance audiometry is superior to pure tone audiometry in detecting middle ear pathology. Tympanometry

  7. Hearing test - Wikipedia

    en.wikipedia.org/wiki/Hearing_test

    The ear canal volume indicates whether a perforation in the eardrum (tympanic membrane) may be present. The middle ear pressure indicates whether any fluid is present in the middle ear space (also called "glue ear" or "otitis media with effusion"). Compliance measurement indicates how well the eardrum and ossicles (the three ear bones) are moving.

  8. Hearing protection fit-testing - Wikipedia

    en.wikipedia.org/wiki/Hearing_protection_fit-testing

    Earplugs with probes for MIRE measurements. Also referred to as F-MIRE (field microphone in real ear). This method measures attenuation by placing a small microphone inside the ear canal while hearing protection is worn. Sound pressure levels (SPL) are measured inside and outside of the ear simultaneously and used to calculate a PAR. [24]

  9. Electrocochleography - Wikipedia

    en.wikipedia.org/wiki/Electrocochleography

    Reference (inverting) electrodes can be placed on the contralateral earlobe, mastoid, or ear canal. The signal is processed, including signal amplification (by as much as a factor 100000 for extratympanic electrode recordings), noise filtration, and signal averaging. A band-pass filter from 10 Hz to 1.5 kHz is often used.
