Peter W. Lenz

Peter W. Lenz is a Teaching Associate Professor in the Department of Psychology at the University of Wisconsin-Milwaukee, part of the College of Letters and Science. He is actively involved in teaching and research, with a focus on auditory perception and speech intelligibility.

Research Interests: Dr. Lenz's research investigates how high-amplitude speech signals can suffer from intelligibility rollover, particularly affecting users of hearing assistive devices. His work explores how interpolated noise and subcritical speech bands can preserve or enhance speech clarity at high volumes. This research has implications for hearing aid design and auditory neuroscience, particularly in understanding neural firing saturation and lateral inhibition in the auditory pathway. His work bridges experimental psychology, acoustics, and assistive technology development.

Recent Publications Trends: His publications from 2011 to 2023 show a consistent focus on speech band filtering, noise interpolation, and intelligibility preservation at high intensities. The research employs psychoacoustic experiments and acoustical modeling, often published in the Journal of the Acoustical Society of America. The work increasingly addresses neural mechanisms underlying perception, suggesting a deepening integration of cognitive and physiological models.

Teaching: Dr. Lenz teaches foundational and advanced courses including Psych 101 (Introduction to Psychology), Psych 325 (Research Methods), Psych 503 (Perception), and Psych 623 (Perceptual Processes), contributing significantly to the psychology curriculum.

Education:

• Ph.D. in Psychology, University of Wisconsin-Milwaukee, 2005

Advising and Grants: While no formal students or grant funding are mentioned in the text, Dr. Lenz leads the Auditory Perception Laboratory at UWM, suggesting involvement in mentoring undergraduate and graduate researchers. His sustained publication record indicates ongoing research activity, potentially supported by internal or external funding.

Laboratory: He conducts research through the Auditory Perception Laboratory at UWM, where experimental studies on speech processing and perception are carried out.
