Understanding hearing
Date:12/2/2013

rception of sound. Unfortunately, this "coding" is still poorly understood by science.

"Getting implants to operate more precisely will require strategies that are better geared to the information processing of the neuronal circuits in the brain. The prerequisite for this is a better understanding of the auditory system," explains Professor Werner Hemmert, director of the Department for Bio-Inspired Information Processing, at the TUM Institute of Medical Engineering (IMETUM).

Based on physiological measurements of neurons, his working group successfully built a computer model of acoustic coding in the inner ear and the neuronal information processing by the brain stem. This model will allow the researchers to further develop coding strategies and test them in experiments on people with normal hearing, as well as people carrying implants.

The fast track to better hearing aids

For manufacturers of cochlear implants collaborating with the TUM researchers, these models are very beneficial evaluation tools. Preliminary testing at the computer translates into enormous time and cost savings. "Many ideas can now be tested significantly faster. Then only the most promising processes need to be evaluated in cumbersome patient trials," says Werner Hemmert. The new models thus have the potential to significantly reduce development cycles. "In this way, patients will benefit from better devices sooner."
