Jennifer J. Lentz, PhD
Education
1998 PhD Bioengineering, University of Pennsylvania
Research
My research interests include human auditory perception in normal-hearing and hearing-impaired listeners, the application of psychological models to perceptual phenonmena, and the development of better tools to assess and characterize tinnitus. In particular, I am interested in how the auditory system represents distinct auditory signals and how the auditory system integrates relevant information to yield a unified auditory percept. Our lab also evaluates the effects of hearing loss on those perceptual processes. Recent work has been directed towards methods that might work better for assessing patients with tinnitus in the clinic. A few of our relevant publications are:
Lentz, He, & Townsend, J. T. (2014) "A new perspective on binaural integration using response time methodology: super capacity revealed in conditions of binaural masking release," Frontiers in Human Neuroscience, 8, 1-16.

Chad Bullard, BS, PhD Student
Education
2021 BS Music Technology, Georgia Institute of Technology
Research
Chad Bullard is currently pursuing a Ph.D. in Hearing Sciences in the Department of Speech, Language, and Hearing Sciences. Their research interests include qualitative descriptions of audio and the ways that our perception of these qualities change with various forms of processing. Initial work, under the guidance of Dr. Jennifer Lentz, will focus on the impact of compression algorithms on the perception of “warmth” and “brightness” in audio samples.
