This paper proposes a novel algorithm to estimate the direct-to-reverberant energy ratio (DRR) using hearing aid microphones. The algorithm is based on the interaural magnitude-squared coherence of signals and is able to take both phase and level differences of microphones signals in the binaural configuration into account.

Abstract A novel scheme of binaural sound localization and dereverberation in reverberation environment is present in this paper. The performance of cross-correlation based traditional time-delay estimation method is degraded sharply in a reverberation environment.

Lower Interaural Coherence in Off-Signal Bands Impairs Binaural Detection [PDF]
Journal of the Acoustical Society of America, 2022 Differences in interaural phase configuration between a target and a masker can lead to substantial binaural unmasking. This effect is decreased for masking noises with an interaural time difference (ITD).

Interaural coherence and the lateralization of noise by interaural level differences
The Journal of the Acoustical Society of America, 2001Coherent noise, with an interaural cross correlation of unity, and incoherent noise, where signals to left and right ears are independent, sound very different. The former produces a compact lateralized image. The latter produces a diffuse image that fills the head. Nevertheless, listening experiments show that coherent and incoherent noise images seem

Anomalyous interaural coherence minima near 45 degrees
The Journal of the Acoustical Society of America, 2007High-resolution (200 kHz sample rate) measurements of interaural coherence for a KEMAR manikin were made in an anechoic environment. As the angle of incident sound was varied in the horizontal plane, there was a minimum in coherence around ±45°.

Interaural Time Delay of Speech with Coherent and Incoherent Noise
The Journal of the Acoustical Society of America, 1973The matter of the “magic number” for interaural delay has occupied the attention of numerous investigators for the past few years. Some have reported that delays around 50 msec between ears produce effects different from those found when the delays are some other value; others have reported the same phenomenon but with the “magic number” set around 60 ...

Speech segregation in rooms: Importance of the interferer interaural coherence
The Journal of the Acoustical Society of America, 2008When an interferer is present, reverberation degrades speech intelligibility not only by its direct effect on the target, but also by affecting the interferer [Lavandier & Culling, J. Acoust. Soc. Am., 122 (3), 2007]. This latter effect occurs at lower levels of reverberation than the former intrinsic degradation of the target, and can be explained

The effect of binaural coherence on envelope interaural time difference thresholds.
The Journal of the Acoustical Society of America, 2010Room reflections alter the envelope of sounds differently at both ears, reducing binaural coherence. Experiment 1 measured interaural time difference (ITD) discrimination thresholds for broadband and transposed speech. A sentence was convolved with binaural room impulse responses for different source-receiver distances, and the envelopes extracted and ...

The Journal of the Acoustical Society of America
Interaural time difference (ITD) cues are the dominant cue for sound localization in the horizontal plane. Encoding of ITD is postulated to occur via an internal binaural cross-correlation function, where the peak correlation serves as the interaural coherence (IAC) and the delay in which the peak occurs serves as the ITD.

Development of sensitivity to interaural coherence for binaural fusion
The Journal of the Acoustical Society of AmericaBinaural fusion reflects the ability to combine signals from the two ears into a single percept. For normal-hearing adults, increasing interaural coherence or the statistical similarity of the signals at the two ears promotes binaural fusion. How children fuse binaural signals of varying interaural coherence is unexplored. The goal of this study was to
