Written in an engaging, easy-to-read format by three of the industry's leading experts, Speech Mapping and Probe Microphone Measurements is an essential clinical companion for all practitioners fitting and dispensing hearing aids.

The key to successful hearing aid fittings is the patient-specific programming of gain and output. As outlined in all Best Practices Guidelines, the cornerstone of this process is the real-ear verification. Although speech mapping and probe-microphone measures have been used clinically for decades, new techniques and procedures continue to emerge. This is the first handbook to be published in 25 years that is dedicated to this critical clinical measure.

Starting with an emphasis on evidenced-based practice, and the need to develop a well-researched gold standard, Speech Mapping and Probe Microphone Measurements takes you through the process of conducting valid and reliable speech mapping testing. Following a review of the basics of signal types, presentation levels, and patient and probe positioning, the chapters flow to the patient-centered real-ear verification process. In addition to extensive step-by-step guidelines regarding the routine testing and adjustment of gain and output, protocols for the evaluation of special features and fittings also are outlined. As a bonus, the authors provide a review of how speech mapping findings can be used with other measures that are part of the overall hearing aid fitting protocol.

Douglas L. Beck, AuD, speaks with Gus Mueller in the August 2017 issue of The Hearing Review about speech mapping, probe-microphone measurements, and the verification of prescriptive targets in hearing aid dispensing and hearing healthcare.
