Ease of language understanding in noise: mismatch in the short-term and long-term
2011 (English)Conference paper (Other academic)
A working memory based model for Ease of Language Understanding (ELU) hasbeen developed (Rönnberg, 2003; Rönnberg et al., 2008). It predicts that speechunderstanding in adverse conditions, for example in the presence of high levels ofbackground noise, phonological distortion or misleading semantic context, is dependenton explicit processing resources such as working memory capacity. Thispresentation will outline the details of this prediction by addressing (1) how matchingvs. mismatching semantic cues affect speech understanding at differentSNRs behaviorally and neurally, (2) how working memory capacity interacts withsignal processing in hearing aids under “high degradation” (i.e. modulated noise,fast compression) and “low” degradation (i.e. steady state noise, slow compression)conditions, and (3) how different memory systems are selectively affectedby hearing impairment.
