PeopleStaffJoseph G. Desloge, PhD, Research Scientist, received his B.S degree in electrical engineering from Cornell University and his S.M. and Ph.D. degrees in electrical engineering from the Massachusetts Institute of Technology where his research involved the development of improved background-noise cancellation systems for hearing aid use. After completing his Ph.D., he served as a Research Scientist on the staff of M.I.T. implementing and evaluating directional hearing aid systems and developing novel acoustic surveillance/environmental awareness systems for the military. Since 1999 he has been a Research Scientist at Sensimetrics Corporation where his work includes (1) the design, real-time implementation, and evaluation of improved hearing protection systems that use array processing and automatic gain control techniques to combine hearing protection with acoustic environment awareness and (2) the design, real-time implementation and evaluation of hearing loss simulation systems that allow normal-hearing wearers to experience, in real-time, the comprehension limitations and sense of isolation experienced by hearing impaired people. He has authored and co-authored papers appearing in IEEE Transactions on Speech and Audio Processing and the Journal of the Acoustical Society of America. papers | personal web page | cv
Ray Goldsworthy, PhD, Research Scientist, received his B.Sc. degree in Physics from the University of Kentucky in 1997. He received his Ph.D. degree in Speech and Hearing Bio-Sciences and Technology through a joint program between Harvard University and the Massachusetts Institute of Technology. His doctoral thesis focused on noise-reduction algorithms and performance metrics for improving speech reception in noise for cochlear implant (CI) users. Ray is a CI user himself and personally aware of the hearing difficulties that CI users have in the presence of background noise. At Sensimetrics, he has led a project to develop a real-time noise-reduction prototype to improve speech reception in noise for CI users. Ray is also interested in psycho-acoustic modeling of the perceptual differences between CI users and normal hearing listeners. He developed a psycho-acoustic model for his thesis that accurately predicts performance for CI users in a variety of conditions, including non-linear operations such as noise-reduction strategies. papers | personal web page | cv
Samantha Wood Goddess, Chief Financial Officer, received a B.A. in International Relations from Tufts University in 1995 and joined Sensimetrics in 1996. Ms. Goddess is responsible for the company’s financial strategy and its execution, the negotiation of license agreements and subcontracts, and sales and marketing of Sensimetrics’ products. In addition, she oversees all aspects of grants and contracts administration, including compliance with FAR/DFARS regulations, DCAA audits, and negotiation of indirect cost rates with both DHHS and DoD. papers | personal web page | cv
Jens Jorgensen, Art Director / Designer, received a fine arts diploma from The School of the Museum of Fine Arts, Boston. He has been working in the field of multimedia and design since 1993 when he first consulted on CD-ROM development projects for Microsoft and SAP. While at Sensimetrics, Jens has designed interface and navigational structures, and created animation, sound and video content for the company’s multimedia and software packages. He is responsible for Sensimetrics’ web-based and printed design for marketing and package design, and some industrial design. He also acts as the company’s webmaster and system administrator. Outside of Sensimetrics, Jens developed a digital audio recording studio, analog/digital delivery system and digital archive process for Perkins School for the Blind. When completed in 2001, Perkins was the first volunteer-based audio book studio operating a digital production system in the US. papers | personal web page | cv

Patrick M. Zurek, PhD, President, Company Director, received his doctoral degree in Experimental Psychology from Arizona State University in 1976. From that time until 1981 he was a Research Associate at the Central Institute for the Deaf in St. Louis, where his principal work was on otoacoustic emissions from human and animal ears. In 1981, he joined the Communications Biophysics Group at the Massachusetts Institute of Technology, where he was a Principal Research Scientist. His work there focused on the behavioral study of hearing impairment and its rehabilitation through hearing aid signal processing. Dr. Zurek has published numerous papers and book chapters on these and other topics in psychoacoustics (CV) and has been a reviewer of manuscripts and grants in his field. He is a member of the Auditory Society of America and a Fellow of the Acoustical Society of America. In 1999 Dr. Zurek succeeded Robert Berkovitz as President of Sensimetrics where he has been engaged in a variety of research projects relating principally to the development of novel technology for hearing. The subjects of these development projects have included: a headset-style assistive listening device; a hand-held digital instrument for infant hearing screening; an audiometric spatial-hearing test system; interactive courseware for instruction in Hearing Science; advanced hearing protectors; MRI-compatible earphones; and hearing loss simulations for audiology. papers | personal web page | cv
Consulting Scientists
Nathaniel
I. Durlach,
Consultant, Company Director, is a Senior Scientist in the
Department of Electrical Engineering and Computer Science at
MIT. Initially trained as a mathematician, he was employed by
the MIT Lincoln Laboratory from 1954 to 1963 to help develop
improved radar air defense systems. Subsequently, he became
interested in the study of living systems. His research on
living systems has been very broad, ranging from the study of
echolocation systems in bats and necrophoric behavior in ants to
topics in the social sciences; however, his main focus has been
the sensorimotor performance of humans and, in particular,
auditory and tactile psychophysics.
He
is Co-Director of the Sensory Communications Group in the
Research Laboratory of Electronics at MIT, and a Visiting
Scientist in the Biomedical Engineering Department of Boston
University. He is the author (or co-author) of numerous book
chapters and of roughly 100 refereed articles in such journals
as Perception and Psychophysics and the Journal of the
Acoustical Society of America; he reviews articles, proposals,
and research programs in the field of psychophysics. He has been
awarded the Silver Medal of the Acoustical Society of America
for his contributions to psychoacoustics. He has functioned as
Principal or Co-Principal Investigator on dozens of research
grants at MIT. He is a Co-Founder of the Fayerweather Street
Elementary School in Cambridge. During the past few years, Mr.
Durlach's interests have focused on teleoperator and
virtual-environment systems, with special emphasis on the
human-machine interface used in such systems. He is Co-Founder
and Director of the MIT Virtual Environment and Teleoperator
Research Consortium (VETREC), as well as Co-Founder and
Editor-in-Chief of the MIT Press journal PRESENCE: Teleoperators
and Virtual Environments. He recently served as Chair of the
Committee of the National Academy of Sciences charged with
establishing a national research agenda for research and
development of teleoperators and virtual environments. papers | personal web page | cv
