Distinguished Professor Emeritus, City University of New York. Adjunct professor, Dept. of Surgery, University of CA San Diego. Scholar in Residence, San Diego State University. Visiting Researcher, Dept. of Engineering, University of CA San Diego. Short Bio Arthur Boothroyd was born in England in 1936. He obtained a degree in Physics from the University of Hull in 1957. After a year in electronics research and four years as a high school Physics teacher, he became interested in deafness as a result of having a son with hearing loss. In 1962 he took a research fellowship in the Department of Audiology and Education of the Deaf at the University of Manchester. Following two years of research on earmold design and acoustic feedback in hearing aids, he was hired as an Assistant Professor of Audiology. In 1968 he was awarded the Ph.D. degree for his research on speech perception and hearing aid fitting in hearing-impaired children. Soon after, he moved to the United States where he served as Director of Research and Clinical Services at the Clarke School for the Deaf in Northampton Massachusetts. In 1981, he joined the faculty of the Doctoral Program in Speech and Hearing Sciences at the City University of New York, eventually attaining the rank of Distinguished Professor. He left that position in 2000 to move to California, where he remains active as a teacher, researcher, and consultant. Dr. Boothroyd has published extensively on the effects of hearing loss on development, with special emphasis on speech perception, its assessment, and its enhancement with hearing aids, cochlear implants, and tactile aids. More recently, he has published on room acoustics and electrophysiological response to acoustic change. He was formerly part of a team studying, and developing tools for, the rehabilitation of hearing-impaired children and adults under a grant to Gallaudet University from the National Institute of Disability Rehabilitation and Research. In addition, Dr. Boothroyd has consulted on the design and application of FM and Sound-Field amplification systems and has offered courses on Aural Rehabilitation at San Diego State University. He serves on the Board of the Auditory Oral School of New York in Brooklyn. Current research deals with user self-fitting and post-fitting self-readjustment of Hearing aids.
