In the second of three books on hearing aids, Bentler, Mueller, and Ricketts focus on verification and validation procedures, matters that clinical audiologists devote most of their science to. They cover evidence-based practice; electro-acoustic and other quality control techniques; corrections, conversions, and calculations; prescriptive formulas and programming; behavioral assessment during clinical fittings; probe-microphone measures: rationale and procedures; probe microphone clinical uses; hearing aid orientation and troubleshooting; auditory rehabilitation; and validation: self-report outcomes. The first book is about pre-fitting and selection, and the third in on signal processing. Annotation ©2016 Ringgold, Inc., Portland, OR (protoview.com)
