Common Evaluation Schemes for audiological algorithms

This section contains the outcomes while working as a postdoctoral researcher within the framework of the ICANHEAR project working on ”Common Evaluation Schemes (CES) for audiological DSP algorithms” at the group of Professor Norbert Dillier (University Hospital Zurich/University of Zurich)

 

The last years, there has been a significant effort in the scientific community for the deeper understanding of the auditory mechanisms and the improvement of the algorithms and the acoustic signal coding schemes, employed in hearing devices. These on-going research efforts lead to the development of novel methods for the enhancement of the acoustical signal; however their efficiency, performance and potential advantage compared to existing solutions should be examined.

This has recently increased the need of a universal, standardized, common methodological framework for the assessment of the various introduced Digital Signal Processing (DSP) algorithms. In the field of hearing aid–related technologies no standard procedures are being followed up to now and the various private/public research insitutes working in this field usually follow their own methodological approaches. However, for many reasons, it would be beneficial to establish some Common Evaluation Schemes (CES) by providing guidelines and series of tools to the scientific community that could assist in this direction.
