Crosstalk cancellation (XTC) yields high-spatial-fidelity reproduction of binaural audio through loudspeakers allowing a listener to perceive an accurate 3-D image of a recorded soundfield. Such accurate 3-D sound reproduction is useful in a wide range of applications in the medical, military and commercial audio sectors. However, XTC is known to add a severe spectral coloration to the sound an...

The problem is addressed of reproducing a desired sound field in the interior of a bounded region of space, using an array of loudspeakers that exhibit a first order acoustic radiation pattern. Previous work has shown that the computation of the required loudspeaker signals, in the case of omnidirectional transducers, can be determined by solving an equivalent scattering problem. This approach ...

Multiple-driver dodecahedron loudspeakers are commonly used in room acoustics measurements as omnidirectional sources of sound. Yet they and other regular polyhedron loudspeakers become “multidirectional” above their omnidirectional cutoff frequencies often near 1 kHz . Because these cutoff frequencies normally fall within common measurement bandwidths, one might question whether anything is re...

Auralizations can be computed in a variety of ways as well rendered over different sound reproduction systems. They are used design tool architectural projects and for fundamental studies on spatial perception cognition, hence requiring reliability confidence the obtained results. This study assessed this through auditory stability by comparing perceived differences between two rendering system...

This paper describes an acoustic system enabling us to achieve asymmetric transmission over a broad frequency range. The basic elements of the are moving coil loudspeaker placed along axis duct, and microphone flush mounted next front side loudspeaker. acts both as mass-spring oscillator through which incident waves reflected transmitted, sound re-emitter controlled by feedback loop. It is show...
