Monaural phase sensitivity with Ronken’s paradigm

This paper describes an experiment using stimuli (pairs of clicks or pulses) similar to those used by Ronken [J. Acoust. Soc. Am. 47, 1091–1099 (1970)] in one part of his investigation of monaural phase sensitivity. The main difference between the studies is that Ronken’s basic pulses were 250 μs in duration whereas ours were 20 μs in duration; phase discrimination fails in Ronken’s experiments when pulse separation is less than about 2 ms but phase discrimination in our experiment fails only when the pulse separation is made less than 200 μs. We consider three different explanations of the results.
