Laurel Carney

Visiting Professor at Hearing Systems

Friday 24 Feb 17
At the moment Laurel Carney, Marylou Ingram Professor in Biomedical Engineering, University of Rochester, New York, is Visiting Professor at Hearing Systems, DTU Electrical Engineering. Laurel Carney’s combined expertise in physiology, behavioral research and computer modeling gives new dimensions to hearing research.

In order to reach the research area which occupies Laurel Carney, acclaimed Professor in Biomedical Engineering, you’ll have to go past the auditory canal, the eardrum and beyond the cochlea into the midbrain. Laurel Carney focuses on the complex network of nerve fibers further into the auditory system than the auditory nerve, and how important the neural responses are for transmitting the inner ear’s signals to the brain. Her research combines neurophysiological and behavioral studies with computer modeling in an effort to develop hearing aids that make human speech clearer.

As a part of a one year Fellowship from her University, Laurel Carney is staying in Denmark for half a year. In the autumn 2016 she was at the University of Oldenburg, the Department of Neuroscience, working with Professor George Klump, and now she will stay for the spring in Denmark. In this way, she will be able to immerse herself in two of the main areas of her research, neuroscience and modelling in human hearing.

"Laurel Carney's expertise in physiology, behavioral research and computer modeling makes it exciting to work with her and we are proud to have her here as a Guest Professor"

The exciting thing and really the reason for coming here is that this group has a long history of studying modulations,” she says.

Through computer modeling it is possible to simulate background noise, different degrees of hearing loss, read the changes and decode the neural information in response to sound fluctuations. This work may be important for the development of hearing aids for listening in background noise. Her research group in Rochester makes recordings of how the neurons respond to sounds, and the scientists are actually able to compare the detection patterns from parakeets to their behavior. Then they can compare behavioral abilities of parakeets and humans. In this way they hope to find out how the neurons in the brain are coding sound.

“We try to learn about the bird brain's strategy for discriminating complex sounds, and we believe it must be comparable to the human strategy, humans and some birds listening behavior are so similar. Timing in background noise is important to understand and we need to understand how hearing loss would affect that timing,” she explains.

Torsten Dau, Professor and Head of Hearing Systems, is very pleased to have Laurel Carney, who is acknowledged worldwide, as Visiting Professor in the research group:
“Laurel
Carney's expertise in physiology, behavioral research and computer modeling makes it exciting to work with her and we are proud to have her here as a Guest Professor,” he stresses.
