German Annual Conf. Acoust.

For example, in laboratory experiments, the combination of a leading (direct) sound followed by a lagging (reflected) sound is localized in the direction of the leading sound. This study was designed to measure the degree to which the interaural coherence of leading and lagging sounds, respectively, affected performance. The coherence of leading or lagging sounds was varied by either presenting a sound from a single loudspeaker or by presenting mutually uncorrelated versions of sounds from 5 adjacent loudspeakers. The listener’s task was to point to the perceived location of leading and lagging sources of sounds which were 10-ms long, low-pass filtered white noises, or 2- second long tokens of speech. The leading and lagging stimuli were presented either from speakers located directly in front of them or from speakers located +/- 45◦ to the right or left. The results indicate that leading coherent sounds influence perceived location more so than do leading incoherent sounds. This was true independent of whether sounds were Gaußian noises or tokens of speech.} }
