摘要: The position‐variable model [R. M. Stern, Jr., and H. S. Colburn, J. Acoust. Soc. Am. 64, 127–140 (1978)], which had been developed to describe binaural phenomena at 500 Hz, is extended predict lateralization detection frequencies of 250–1200 Hz. major modification made the use a frequency‐dependent form function that describes relative number coincidence detectors in as their internal delay. This fitted pure tones with fixed ITD over range frequencies, ratio N0Sπ NπS0 thresholds. without further general dependence lateral position on frequency, amplitude‐modulated tones, ‘‘dominant region’’ phenomenon.
