Frequency selectivity in amplitude modulated sound have been reported in terms of modulation threshold level for amplitude-modulation detection, where a pink or white noise carrier was modulated with a sinusoid and band-limited white noise, which showed similar band-pass type masking characteristics. Such previous studies treated band limited white noise carriers. In this paper, an amplitude-modulation detection level is measured in the case of sinusoidal carrier. The obtained characteristics are similar to those for pink or white noise carriers; the detection level increases around 16Hz when the 1000Hz sinusoidal carrier is modulated by 16Hz pure tone and band-limited white noise, and the increase is localized around 16Hz within 1 to 1.5 octave wide.
