The process of grouping frequency components belongingto one sound source and segregating them from frequency components originatingfrom a different sound source can be accomplished by using a variety of acousticproperties (so-called “cues”) of which harmonicity, time of onset and spatial cuesare among the most important. As natural sounds provide more than one cue togroup or segregate frequencies, it is crucial for understanding a complex acoustic sceneto investigate how combined cues are processed by the auditory system. Gainingknowledge about the mechanisms of processing more complex stimuli is valuable forthe (further) development of technical solutions in audiology, for example for theapplication in hearing aid devices.
