Research

The research in dB SPL is motivated towards identifying problems that hearing-impaired listeners encounter in daily life, with the ultimate goal of proposing solutions to these problems. To achieve this goal, we conduct basic science research to understand mechanisms of hearing, or its failures, as well as clinical research with actual patients. Our research is multidisciplinary, and involves behavioral and cognitive sciences, as well as engineering approaches. We work closely with users of hearing aids and cochlear implants, the manufacturers of these devices, and local and international collaborators.

Some of our projects (selected) are as follows. To see a more comprehensive list please see the People section. For useful tools for lab members and non-members, we now have a google lab website.
