Topic of this paper is an interactive sound reproduction system to create virtual sonic environments and visual spaces, called Virtual Audio Reproduction Engine for Spatial Environments (VARESE). Using VARESE, Edgard Varèse’s Poème électronique was recreated within a virtual Philips Pavilion. The system draws on binaural sound reproduction principles including spatialization techniques based on...

Audioconference participants often have difficulty identifying the voices of other conferees, especially in ad hoc groups of unfamiliar members. Simultaneous presentation of multiple voices through a single, monaural channel can be discordant and difficult to comprehend. To address these shortcomings, we have developed the Vocal Village, a communications tool that allows for real-time spatializ...

Head-related impulse responses measured in a classroom are used to generate realistic “reverberant” inputs to a physiologically-based model of binaural processing in the brainstem. Results show that instantaneous information provides relatively poor source direction information, even though human perception is only slightly affected by reverberation. However, analyses of the distortion of spati...

A scheme is presented for encoding general complex sources in high-order Ambisonic soundfields, with control over position and orientation. Also reviewed is related work by the author on the binaural rendering of nearfield sources, accounting fully for the physical constraints of this problem. Together these developments provide a means for creating high quality nearfield auditory displays over...

Ceiling shapes for concert halls are proposed that, on the basis of prior extensive subjective evaluations, should result in high listener preference of the hall's acpistoca; response tomusic. These shapes are based on the premise that as little as possible of the early sound energy should arrive at a listener's ears in the "median" plane (the vertical symmetry plane through the listener). Whil...

Abstract Introduction Binaural beats are an auditory phenomenon when two sounds with a certain frequency difference transmitted simultaneously to each ear, one perceives beat exactly equal that difference. Previous studies have shown binaural synchronize neural oscillations and induce related brain states behaviors. One previous study showed listening at 1 Hz during naps increased the duration ...

When two tones with slightly different frequencies are presented to both ears, they interact in the central auditory system and induce the sensation of a beating sound. At low difference frequencies, we perceive a single sound, which is moving across the head between the left and right ears. The percept changes to loudness fluctuation, roughness, and pitch with increasing beat rate. To examine ...

This study analyzes the influence of binaural beats, an acoustic phenomenon which rises from two sonic waves of insignificantly different frequencies noticed as a single tone on each ear, on brain activity. Although this topic is not new, few scientific reports have been released. Therefore this study investigates if there is a measurable impact on the EEG activity for different frequency bands...

The interaural phase sensitivity of neurons was studied through the use of binaural beat stimuli. The response of most cells was phase-locked to the beat frequency, which provides a possible neural correlate to the human sensation of binaural beats. In addition, this stimulus allowed the direction and rate of interaural phase change to be varied. Some neurons in our sample responded selectively...
