Sensitivity to low-frequency temporal fine structure is correlated with aided spatial release from masking
2010 (English)Conference paper, Poster (Other academic)
• Binaural hearing is necessary for localizing sounds accurately, and for making sense of complex listeningenvironments with many sound sources.• It is important to understand which binaural cues are beneficial for spatial hearing in hearing aid users toinform hearing aid design.• Temporal fine structure, TFS, is thought to be important for voice recognition, segregation of competingtalkers, and listening in the dips of a fluctuating background (Hopkins et al., 2008; Zeng et al., 2005; Lorenzi etal., 2006). Hearing-impaired listeners have a reduced ability to use TFS information (Moore et al., 2006;Hopkins and Moore, 2007; Hopkins and Moore, 2010).• Hopkins and Moore (2010) developed a fast method for measuring sensitivity to binaural TFS (the ability to detectinteraural phase differences, IPD, of pure tones) at low frequencies: the TFS-LF test.• To investigate possible correlations between binaural TFS abilities and spatial hearing, the opportunity wastaken to make use of some earlier data on aided spatial release from masking (Neher et al., 2009). In thatstudy, large inter-subject variation in spatial release from masking was observed, and it was hypothesized thatthis variation could be related to binaural TFS abilities. The TFS-LF test was used with the same subjects as tested byNeher et al.
