  2. 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. [26]

  3. 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. [2]

  4. Pure-tone audiometry - Wikipedia

    en.wikipedia.org/wiki/Pure-tone_audiometry

    Pure-tone audiometry provides ear specific thresholds, and uses frequency specific pure tones to give place specific responses, so that the configuration of a hearing loss can be identified. As pure-tone audiometry uses both air and bone conduction audiometry, the type of loss can also be identified via the air-bone gap .

  5. 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.

  6. Absolute threshold of hearing - Wikipedia

    en.wikipedia.org/wiki/Absolute_threshold_of_hearing

    Measurement of the absolute hearing threshold provides some basic information about our auditory system. [4] The tools used to collect such information are called psychophysical methods. Through these, the perception of a physical stimulus (sound) and our psychological response to the sound is measured. [9]

  7. ITU-R 468 noise weighting - Wikipedia

    en.wikipedia.org/wiki/ITU-R_468_noise_weighting

    The human ear responds quite differently to clicks and bursts of random noise, and it is this difference that gave rise to the CCIR-468 weighting curve (now supported as an ITU standard), which together with quasi-peak measurement (rather than the rms measurement used with A-weighting) became widely used by broadcasters throughout Britain ...

  8. Acoustic reflex - Wikipedia

    en.wikipedia.org/wiki/Acoustic_reflex

    The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.

  9. 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
