EducationPh.D. (Electrical Engineering/Bioengineering), Northwestern University, 1971Courses TaughtEE 0031 Linear Circuits and Systems 1 Professional InterestsDr. Boston's interests include signal processing, fuzzy signal detection, and intelligent control. He teaches courses in signals and systems and digital signal processing. His current research is concerned with techniques to modify a speech signal to increase its intelligibility in noise.

Research InterestsThe role that outer hair cells in the cochlea play in speech processing is not known, but they have been suggested to be involved in auditory nerve tuning, two-tone suppression and the processing of noisy speech. We have proposed that outer hair cells may be involved in the detection of transient components in speech and that these transients are important for the understanding of speech in noisy conditions. We are using time-frequency analysis techniques to identify speech transients and are investigating whether amplification of these transients can improve the intelligibility of speech in noise. |
