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.
