Abstract
Spectral integration for several tone-in-noise conditions is discussed
and an experiment is conducted for both monaural (NoSo) and binaural conditions
(NoSp). Monaural detection thresholds for running-noise maskers increased for
masker bandwidths up to the critical bandwidth and remained constant for larger
bandwidths. Binaural conditions and monaural conditions with a frozen-noise
masker revealed different spectral integration patterns that are monotonic for
masker bandwidth below and beyond the critical bandwidth, an effect known as the
apparently wider binaural critical band. Finally, we show a different type of spectral integration obtained for binaural conditions with a reduced masker correlation (NrSp) or for NoSp with an overall interaural level difference. In these cases, the integration patterns are nonmonotonic with a maximum for masker bandwidths around the critical bandwidth.
