Dynamic virtual acoustical reproduction system for hearing prosthesis evaluation


Grämer, T; Müller, M F; Schimmel, S M; Kegel, A; Dillier, N (2010). Dynamic virtual acoustical reproduction system for hearing prosthesis evaluation. In: 13. Jahrestagung der Deutschen Gesellschaft für Audiologie, Frankfurt, 17 March 2010 - 20 March 2010, 1-4.

Abstract

Algorithms for the improvement of speech intelligibility in hearing prostheses can degrade the spatial quality of the audio signal. To investigate the influence on distance perception and localization of such algorithms, a system to virtually render arbitrary static acoustical scenes has been developed (Müller et al., 2010). With this system, the localization of sounds processed by a hearing aid algorithm can be compared to unprocessed sound sources. The existing virtual acoustics system has been extended to present more realistic dynamic scenes, and it can also compensate for head movements of test subjects.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
