Interaction between pitch and timbre cues on auditory stream segregation and grouping.

When a listening environment contains multiple different sounds coming from multiple different sources, they often blend together and become messy, indecipherable noise. Listeners can use various auditory cues, such as pitch and timbre, to focus their attention onto just one sound, effectively drowning out the background noise. This is known as the “cocktail party effect.”  For individuals with normal hearing, this phenomenon occurs effortlessly—but for those with hearing impairments, isolating one sound from a noisy environment is much more challenging. The purpose of this study is to explore the interaction of pitch and timbre cues in an auditory streaming segregation task and determine to what extent listeners with various hearing capabilities utilize these cues in a multi-talker listening environment.
