• A new miniature wide-range electret microphone with a flat frequency response is available to the audiology clinic to measure sound pressure in a patient's ear canal. This article describes the clinical application of this new microphone for the selection and monitoring of hearing aid response. Preliminary results of the relationship between ear canal measurements and functional gain are also provided. This new clinical technique can provide the audiologist with quick objective data on the response of a hearing aid while it is being worn by the patient.
