Real Ear Measurement | Hearing Specialist | Audiologist

Real Ear Measurement is a computerized imaging exam that calculates the extent to which a patient’s hearing loss is improved with a particular hearing aid. The Real Ear Measurement test confirms the appropriate levels of overall loudness and the shape of amplification provided by the patient’s hearing aid.

Real Ear Measurement: Fitting Hearing Instruments

Real Ear Measurement The term Real Ear Measurement is applied to all measurements conducted directly to the patient’s ear. Measurements are conducted with and without the hearing aid being worn. Real Ear Measurement is important for hearing aid fittings because the size and shape of the ear canal influence a hearing aid’s performance significantly.

The shape of the ear is unique, and can be compared to an individual’s fingerprint. So without Real Ear Measurement, only average data can be utilized.

Without accurate measurements, hearing aid devices are subject to over or under amplification. For people who have the ability able to perceive sounds as too loud or too soft do not have such a problem. Although, when it comes to young kids along with the mentally handicapped who don’t have the capacity to describe their perception verbally, there can be issues.

How Real Ear Measurement Works

Noise cues are introduced using a speaker right in front of the patient. A microphone is placed near the ear to determine the sound’s level. A subsequent microphone measures the sound’s strength directly within the ear canal in front oin advance of the ear drum.

Learning the intensity of the audio inside and outside the ear permits the filter to establish the precise amplification as well as output the client receives from the hearing aid and complete the proper adjustments.
