Professor Josef Zwislocki


Distinguished Expert To Discuss Recent Insights On Hearing Process And New
Principals For Hearing Protection

The last fifty years have produced many theories on the concept of how the human ear processes sound. Because today’s audio equipment is designed to balance the characteristics and properties of the human auditory system, the subject of the 119th AES Convention Heyser Memorial Lecture by Professor Jozef J. Zwislocki, will be of particular interest. Scheduled for Saturday, October 8, 2005 at 6:45PM, at NY’s Javits Center the lecture will provide audio professionals with the latest findings on how the human ear processes sound and suggested methods for protecting the inner ear.

“Dr. Zwislocki’s distinguished career in engineering and neuroscience has provided him with invaluable theoretical and practical experience on hearing loss,” says AES Technical Council Chair and incoming president-elect, Wieslaw Woszczyk. “His work at the Psychoacoustic Laboratory at Harvard and with the Organization of Bioacoustics Lab at Syracuse has yielded major breakthroughs in the rapidly evolving area of sensory communications. We are privileged to have Dr. Zwislocki share his insights as the Heyser Lecturer.”

The lecture will address such pivotal subjects as; the physiological mechanisms of the auditory system; the inner ear, sound analysis and sound transduction into neural activity. Dr. Zwislocki will discuss the development of these concepts and introduce a new principle for protecting the vulnerable cochlear hair cells against environmental noise.

Since obtaining his engineering degree in 1945 from the Swiss Federal Technical Institute, Dr. Zwislocki has specialized on psychophysics and auditory biophysics. He has performed extensive research on the auditory system, its psychophysics, biophysics and psychophysiology. A Fellow of the Acoustical Society of America and American Speech Language and Hearing Association, Dr. Zwislocki is Distinguished Professor Emeritus Biomedical & Chemical Engineering at Syracuse Univesity. He has earned such distinctions as the international Amplifon Prize, Javits Neuroscience Investigator Award, and the Award of Merit for the Association for Research in Otolaryngology.

“Hearing loss is a major tragedy for anyone, but particularly for audio industry professionals,” AES Convention Chair Jim Anderson adds. “Dr Zwislocki’s address should be considered a critical wake-up call to our attendees regarding the importance of hearing protection. We are very pleased to provide a forum for his invaluable findings.”


Formed in 1948 by a group of concerned audio engineers, the Audio Engineering Society counts over 12,000 members throughout the U.S., Latin America, Europe, Japan and the Far East. The AES serves as the pivotal force in the exchange and dissemination of technical information for the industry. For additional information on the AES 119th Convention please visit
