| dc.description.abstract | The effect of reflections on an individual's auditory distance perception has been widely studied in an enclosed space but has received less attention when conducted in an open air outdoor space. Auditory distance judgments were assessed for 14 normal hearing and normal visual depth perception participants aged 18 to 50 years. Participants were asked to judge the auditory distance of various sounds presented via a lap top computer and insert earphones. The task was completed using three different noise stimuli (pink noise, pulse train, speech), seven different microphone to loudspeaker distances (1 ft, 2 ft, 4 ft, 8 ft, 16 ft, 32 ft, and 64 ft) and seven different reflection delays (0 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms, and 320 ms). Results revealed that reflection delay did not significantly impact auditory distance perception in a simulated open air outdoor space, but that the combined effects of sound source distance, type of stimuli, and reflection delay interacting together did impact auditory distance judgments in a simulated open air outdoor space. This study further supports the findings of previous literature looking at the combination of various acoustic and non-acoustic effects on an individual's auditory distance perception. | |
