Comments on “Lateralization and the binaural masking-level difference” [G. B. Henning, J. Acoust. Soc. Am. 55, 1259-1263 (1974)]

Henning [J. Acoust. Soc. Am. 55, 1259–1263 (1974)] showed that certain complex waveforms can be lateralized on the basis of interaural temporal differences when the energy in the waveforms is confined to high-frequency regions. However, when the high-frequency waveforms are presented in a background of noise, Henning showed that their detection is not dependent on interaural temporal differences. In the present demonstration experiment these high-frequency waveforms were not as easily lateralized with a noise background as were low-frequency stimuli. This result is consistent with an assumption that lateralization and binaural detection of complex waveforms are not essentially different.
