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.
