Hafter Auditory Perception Lab

University of California Berkeley -- Department of Psychology

Ervin Hafter, Ph. D.

Research Objectives

At the Auditory Perception Lab we are currently conducting research in the area of shared attention, effects of noise reduction on speech cognition, spatial perception of sound, and effects of reverberant environments on users of hearing aids and cochlear implants.

The Ear Club

We organize a weekly auditory colloquium featuring distinguished speakers on a broad range of topics related to hearing science.

Here is the Schedule and Mailing List Information.

Lab Resources

Our main experimental apparatus is an anechoic chamber with a 48-channel digital surround sound system and a digital projector (see photos). This system enables us to convincingly simulate open-field reverberant environments for the exploration of research questions regarding the spatial perception of sound in the natural world. We also have three sound isolation booths with calibrated headphone presentation systems. All of our experiments are carried out using computers and the majority of our programming is done using the Matlab environment.
