Specific Areas of Research

1. Develop an empirical basis for clinical interpretation of otoacoustic emission measurements used to assess hearing loss
2. Understand suprathreshold hearing deficits that may escape detection by conventional audiometric methods
3. Understand the normal growth of loudness, the abnormal growth in ears with hearing loss
4. Develop efficient methods for the clinical measurement of loudness growth at multiple frequencies
5. Develop and validate signal-processing methods for the restoration of normal loudness growth
6. Understanding the measurement and clinical interpretation of cochlear reflectance and development of measurement techniques
7. Understanding the impact of sound delivery devices and stimulus calibration on ear-canal measurements
8. Understanding the origin and functional importance of level-dependence cochlear delays in human ears
