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.

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.
The distal (front) end of the otoscope has an attachment for disposable plastic ear specula. The examiner first pulls on the pinna (usually the earlobe, side or top) to straighten the ear canal, and then inserts the ear speculum side of the otoscope into the outer ear. It is important to brace the index or little finger of the hand holding the ...

The most reliable method for assessing the correct adjustment of a hearing aid is through real ear measurement. [10] Real ear measurements (or probe microphone measurements) are an assessment of the characteristics of hearing aid amplification near the ear drum using a silicone probe tube microphone. [11]

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]
"[The patient] wanted a sparkle in his eye," he explains. A novelty eye can cost anywhere from $2,500 to $5,500 -- about the same range as a regular prosthetic -- but they aren't covered by insurance. Andy recalls one patient who was determined to make a return on his investment: He asked . for an eye that featured the Nike swoosh.
