Blind estimation of reverberation time.
The reverberation time (RT) is an important parameter for characterizing the quality of an auditory space. Sounds in reverberant environments are subject to coloration. This affects speechExpand

On the minimum audible difference in direct-to-reverberant energy ratio.
The goals of this study were to measure sensitivity to the direct-to-reverberant energy ratio (D/R) across a wide range of D/R values and to gain insight into which cues are used in theExpand

Ultrasonic communication in frogs
Among vertebrates, only microchiropteran bats, cetaceans and some rodents are known to produce and detect ultrasounds (frequencies greater than 20 kHz) for the purpose of communication and/orExpand

Encoding of sound duration by neurons in the auditory cortex of the little brown bat, Myotis lucifugus
Responses of 117 single- or multi-units in the auditory cortex (AC) of bats (Myotis lucifugus) to tone bursts of different stimulus durations (1– 400 ms) were studied over a wide range of stimulusExpand

Frequency selectivity in the anuran auditory midbrain: Single unit responses to single and multiple tone stimulation
Summary1.The excitatory response properties of 130 single units in the torus semicircularis of the northern leopard frog (Rana p, pipiens) were recorded. 86% responded maximally to single tones. 14%Expand

Performance of time- and frequency-domain binaural beamformers based on recorded signals from real rooms.
Extraction of a target sound source amidst multiple interfering sound sources is difficult when there are fewer sensors than sources, as is the case for human listeners in the classic cocktail-partyExpand
