This comparison enables the audiologist to make precise adjustments that can have a profound effect upon the listener’s experience. It enables measurement of the sound delivered by a specific hearing aid in the ear canal of a specific individual.


Real-ear measurement is the process of objectively measuring the output and performance of a hearing aid. During real-ear measurement, an Audiologist inserts a flexible tube with the patient’s hearing aid.  The tube is connected to a microphone located outside of the ear.

Tests are performed using the probe-microphone and real-ear measurement software, with the results showing graphs of your amplification prescription target compared to how your hearing aid is actually performing. The graphs depict the real-ear output of the hearing aid for the specific individual.
