Particle-Velocity-Based Mixed-Source Sound Field Translation for Binaural Reproduction

Linear optimal source distribution mapping for binaural sound reproduction

Binaural playback over loudspeakers usually leads to crosstalk. The most effective strategy of general crosstalk cancellation systems is system inversion which, nevertheless, gives rise to several problems such as the loss of dynamic range and the lack of robustness. The optimal source distribution (OSD) method has been utilized to compromise the playback performance and the problems of the cro...

Binaural Hearing and Systems for Sound Reproduction

Manipulation of source width based on sound field reproduction

In this study, a method is proposed to generate an extended virtual source enabling the extension of the perceived source width. In various auditory scenes, a sound source delivers the sensations of its size and location. The perceived source width is a spatial auditory impression related to the source size. Among the source width attributes, individual source width (ISW) is defined as the perc...

Sound field separation with sound pressure and particle velocity measurements.

In conventional near-field acoustic holography (NAH) it is not possible to distinguish between sound from the two sides of the array, thus, it is a requirement that all the sources are confined to only one side and radiate into a free field. When this requirement cannot be fulfilled, sound field separation techniques make it possible to distinguish between outgoing and incoming waves from the t...

A 3d Ambisonic Based Binaural Sound Reproduction System

A computationally efficient 3D real time rendering engine for binaural sound reproduction via headphones is presented. Binaural sound reproduction requires to filter the virtual sound source signals with head related transfer functions (HRTFs). To improve humans localization capabilities head tracking as well as room simulation have to be incorporated. This yields the problem of high-quality, t...
