The traditional two-tone masking technique typically uses a sinusoid or a narrow-band noise as a test signal located at a fixed, specified frequency, midway between two sinusoids. The masked threshold of the test signal is measured as the frequency separation between the maskers is varied in discrete steps. The present study generated the two-tone masker by modulation techniques. The frequency separation between the maskers were varied in discrete steps and also continuously with similar results. When the entire stimulus complex was swept over the audio range, as in the Booth and Brandt study, the threshold data with respect to critical band hypotheses became very complex. Implications of these procedural differences are discussed. [ABSTRACT FROM AUTHOR] |
