|June 1, 1980
Summary
This study compares experimental evoked cochlear mechanical response (ECMR) data with a feedback model. Results show latency measurements align with basilar membrane travel times, validating the model.
Area of Science:
- Auditory Neuroscience
- Bioacoustics
- Biophysics
Background:
- The evoked cochlear mechanical response (ECMR) is crucial for understanding auditory function.
- Accurate modeling of the cochlear mechanical response is essential for diagnosing hearing impairments.
Purpose of the Study:
- To compare experimental ECMR data with an analogue feedback model.
- To investigate the relationship between response latency, frequency, and basilar membrane travel times.
Main Methods:
- Experimental measurement of multiple evoked cochlear mechanical responses.
- Comparison of measured responses with the output of an analogue feedback model.
- Measurement of response latency across different frequencies.
Main Results:
- Experimental ECMR data were compared with the output of an analogue feedback model.
- Response latency was measured for various frequencies.
- Measured latencies were compared with theoretical travel times on the human basilar membrane, showing agreement.
Conclusions:
- The analogue feedback model provides a viable representation of the evoked cochlear mechanical response.
- Latency measurements support the model's ability to predict cochlear signal propagation.
