Jerry L. Punch, Professor

Department of Audiology and Speech Sciences

• B.A., 1965 (Psychology), Wake Forest University
• M.S., 1967 (Audiology), Vanderbilt University
• Ph.D., 1972 (Audiology), Northwestern University

• Current Research Interests:

• Digital hearing aids
• Hearing aid fitting procedures
• Occupational hearing standards
• Hearing handicap scales

Recent studies in my laboratory include investigations of: (1) the role of head shadow and binaural squelch in noisy backgrounds on the aided speech intelligibility of normal-hearing and hearing-impaired listeners, (2) the role of loudness on the frequency-response preferences of normal and hearing-impaired listeners, and (3) the application of multimedia technology to the measurement of hearing handicap.

Current studies include investigations of: (1) the reliability and validity of forced- and unforced-choice paired comparison judgments in the fitting of digital hearing aids, and (2) the development and validation of a Web-based hearing risk inventory for parents of hearing-impaired infants. Some of this work has been conducted in an ongoing collaboration with Professor Brad Rakerd.

Hearing Aid Research Laboratory

The Hearing Aid Research Laboratory is equipped with two PCs; a hearing aid analyzer and real-ear probe-microphone measurement system; an array of audio recording, signal-processing and analysis equipment; and an assortment of calibration and monitoring equipment. This equipment provides the capabilities for simulating and experimentally manipulating a large variety of electroacoustic characteristics used in contemporary analog and digital hearing aids, and for studying the unaided and aided performance of human listeners with normal and impaired hearing.
