Musical scene perception of hearing-impaired listeners

Until recently, hearing impairment has been a blind spot of the map of music perception research. We  aim to provide a conceptual and empirical groundwork that may allow an optimization of hearing aids to music. This involves a host of questions:  How do listeners parse and organize complex musical scenes? How is music listening affected by hearing loss?  Hearing aids are currently optimized for speech -- how can we improve music listening with hearing aids?

Sound onsets: extraction, perception, and modeling

Onset transients have classically been considered as an important acoustical feature for the identification of musical instruments. Here we use a novel sound transient extraction algorithm to more detailedly isolate and study the role of transients and onsets for instrument identification. The subsequent modeling results indicate that onsets possess a wealth of acoustic information that can be exploited by the human auditory system. [Sound examples]

Ambiguity in auditory scene analysis revealed by a timbral Shepard illusion

The famous Shepard illusion yields the impression of an infinitely ascending or descending sequence of pitches.  It can be shown that an analogue phenomenon also works for brightness perception, using stimuli with modulating spectral envelopes. This allows us to raise new questions regarding the mechanisms underlying spectral change perception: under which circumstances are shifts in spectral fine structure (related to pitch) and shifts in spectral envelope (related to timbre) ambiguous? When do they interfere which each other? And what does this tell us about the relation of pitch and timbre perception?  [Sound examples]

Musical timbre perception

What is musical timbre and what does it do in music? What are the acoustic and cognitive factors that affect timbre dissimilarity and brightness perception? Gaining a better understanding of these questions may not only inform the psychological basis of this important auditory parameter, but also improve our general understanding of music perception.
