Several array-processing algorithms were implemented and evaluated with experienced hearing-aid users. The array consisted of four directional microphones mounted broadside on a headband worn on the top of the listener's head. The algorithms included two adaptive array-processing algorithms, one fixed array-processing algorithm, and a reference condition(More)
Measurements and theoretical predictions of auditory target detection in simulated reverberant conditions are reported. The target signals were pulsed 1/3-octave bands of noise and the masker signal was a continuous wideband noise. Target and masker signals were passed through a software simulation of a reverberant room with a rigid sphere modeling a(More)
The lateralization of 250-ms trains of brief noise bursts was measured using an acoustic pointing technique. Stimuli were designed to assess the contribution of the interaural time delay (ITD) of the onset binaural burst relative to that of the ITDs in the ongoing part of the train. Lateralization was measured by listeners' adjustments of the ITD of a(More)
Three effects that show a temporal asymmetry in the influence of interaural cues were studied through the addition of masking noise: (1) The transient precedence effect-the perceptual dominance of a leading transient over a similar lagging transient; (2) the ongoing precedence effect-lead dominance with lead and lag components that extend in time; and (3)(More)

Research is being conducted on a variety of topics concerned with the auditory and tactile senses, particularly with a view to the development of improved aids for the deaf. The supporting grants are listed below. Detailed progress reports are available from the investigators (listed below) and the granting agencies. Publications and talks reporting this(More)
Specific Aims Our long-term goal is to develop improved hearing aids for people suffering from sensorineural hearing impairments. Our efforts are focused on problems resulting from inadequate knowledge of the effects of various transformations of speech signals on speech reception by impaired listeners, specifically on the fundamental limitations on the(More)
