Professor Aronoff鈥檚 research focuses on cochlear implants, with particular interest in bilateral implantation. His work examines how information is combined across the ears and how to divide information between two ears for optimal cochlear implant performance. He developed special software that enables him to create custom processors for cochlear implants, and co-developed a new test to assess whether the processors increase spectral resolution, a key requirement for improving the ability to understand speech in noisy environments.
