Effects of stimulus order on auditory distance discrimination of virtual nearby sound sources

Authors: Simone Spagnol, Rebekka Hoffmann, Árni Kristjánsson, and Federico Avanzini in: The Journal of the Acoustical Society of America 141 Abstract: Stimulus order has been reported to affect perceived loudness. This letter investigates how temporal order affects distance discrimination of receding and approaching pairs of sound sources rendered binaurally in the anechoic near-field. Individual discrimination thresholds for different… Continue Reading Effects of stimulus order on auditory distance discrimination of virtual nearby sound sources
