2-IMAGE LATERALIZATION OF TONES AND CLICKS

When interaural differences of time and level are set into opposition, subjects may report a single image that is determined in its lateralization largely by the interaural level difference. Such images show a fairly large â€ætrading†ratio.†They may report hearing an image that is little affected by the difference of level, but is dependent largely upon the interaural difference of time. Such images show a very small trading†ratio. With practice, subjects can learn to hear and respond to both images, and center either at will. The present study is concerned with both images as they arise from tonal stimuli of various durations and rise fall times, and from high†pass clicks. © 1968, Acoustical Society of America.
