Ear Level FM systems are intended to be used by patients who have normal or near-normal hearing and help increase the signal to noise ratio. They can be used, for example, in classroom settings for a child having learning difficulties or auditory processing disorders (APD). Typical use will include an ear-level FM receiver, coupled to a thin tube, in an open ear configuration. The steps below guide clinicians on how to perform straightforward realear verification of the ear level FM system, in order to verify the maximum output and the recommended volume setting for the FM receiver.
