Cochlear Dead Regions and Implications for Fittings Slides

Pdf Summary

The document is a presentation on cochlear dead regions and its implications for fittings. The presenter discusses the concept of cochlear dead regions, which are areas in the inner ear that have lost the ability to detect certain frequencies of sound due to damage to the inner hair cells. It is explained that cochlear dead regions are not due to damage to the outer hair cells. The presenter also explains how damaged outer hair cells can contribute to cochlear dead regions and the resulting hearing loss.<br /><br />The use of the Threshold Equalizing Noise (TEN) test in diagnosing cochlear dead regions is discussed. The TEN test is a noise that is delivered alongside a tone and is used to determine if there are any dead regions in the cochlea. The results of the TEN test can have implications for fittings, and the presenter provides examples and suggestions for fitting hearing aids in cases of cochlear dead regions.<br /><br />The document mentions that individuals with cochlear dead regions may experience differences in the quality of pure tones at different frequencies, but clarity ratings cannot reliably indicate the presence of dead cochlear regions.<br /><br />The document concludes by providing references for further reading on this topic and invites questions from the audience.
