Research Interests

  • Music perception
  • Musical Acoustics (guitars, fiddles, some wind instruments)
  • Evanescent wave propagation in horns
  • Transducer physics and modeling (Loudspeakers)
  • Wave propagation in inhomogeneous media. Acoustic horns.
  • Models of the outer hair cells of the cochlea. Biophysical model of hair cell membrane mechanical properties, as a function of membrane voltage. (with paul Fahey, Univ. Scranton, physics dept.)
  • Modeling the middle ear in the time domain, with wave models. How does the eardrum transform the acoustic energy and funnel it into the cochlea?
  • Robust human speech recognition
  • Human speech recognition: Reverse engineering, measuring and modeling speech cues used by the human auditory system, when recognizing speech in large amounts of noise and with filtering; Articulation index; confusion matricies; information processing by the auditory system with speech as the signal;
  • Speech and music coding
  • Articulation index modeling of confusion matrix measurements, of consonant vowel sounds, in noise
  • Speech processing for hearing aid applications: Special signal processing techniques for removing reverberation and noise; multiband compression for loudness recruitment abatement;
  • Auditory psychophysics: Intensity just noticable difference (JND), speech psychophysics; confusion matricies; information processing by the auditory system
  • Noninvasive diagnostic testing of the cochlear and middle ear: Otoacoustic emissions measured in the ear canal; noninvasive diagnositcs; distortion product measurements; SFOAE; impedance; power reflectance of the ear canal;
  • Cochlear modeling: Mathematical models of cochlear function, including basilar membrane motion, biophysical models of outer hair cells; models of the micromechanics, including the tectorial membrane and cilia motions.
