Chapter 5: Setting the Hearing Aid Response and Verifying Signal Processing and Features with Real-Ear Probe Microphone Measures
Abstract
The real-ear probe microphone system provides a powerful tool to individual hearing aid fittings accounting for your patient's hearing and ear canal characteristics. The primary treatment for hearing loss is audibility, returning an audible signal across frequencies and input levels given the constraints of the hearing loss. This chapter will provide detailed information on the measures needed to individualize the hearing aid fitting and will present various clinical scenarios that will allow you to work with this information and see how you apply this knowledge clinically. You will explore the verification of signal processing and features that allow you to support your patients.
