JUNGLE ACOUSTICS II: LOCALIZATION OF SOUNDS IN THE JUNGLE.

Abstract

The US Army Tropic Test Center conducted a study of sound localization in the Canal Zone jungle during December, 1966. Localization errors were high in the jungle. Errors were highest for pure tones, next highest for continuous noises, and lowest for impact noises. Low frequencies were easier to localize than higher frequencies. Distance had a significant influence on the size of the localizing error only if reversal errors were included in means. The size of the localization error was highly dependent on the direction angle of the sound. Constant errors in localizing responses were found; their strength and direction depended strongly on direction angle. Background environmental data are also presented.
