Measurement of the diffuse field sound absorption using a sound field synthesis method
Acta Acustica, 2023 A method for measuring the diffuse field sound absorption coefficient of a material using sound field synthesis is proposed. A planar loudspeaker array is first used to generate acoustic plane waves with variable incidence angle on the surface of a ...

Assessing localization accuracy in sound field synthesis [PDF]
Journal of the Acoustical Society of America, 2017 Sound field synthesis methods like Wave Field Synthesis (WFS) and Near-Field Compensated Higher Order Ambisonics synthesize a sound field in an extended area surrounded by loudspeakers. Because of the limited number of applicable loudspeakers the synthesized sound field includes artifacts. This paper investigates the influence of these artifacts on the

Diffuse sound field synthesis: Ideal source layers
Acta AcusticaCan uncorrelated surrounding sound sources be used to generate extended diffuse sound fields? By definition, targets are a constant sound pressure level, a vanishing active sound intensity, and uncorrelated sound waves arriving isotropically from all ...

Novel Tool Path Generation Method for Pocket Machining Using Sound Field Synthesis Theory
Machines, 2023 Contour parallel tool paths have been proved to be a preferred machining strategy for their advantage of less tool retractions and less sharp turns. The traditional geometrical algorithm-based tool path generation method often makes it hard to simply and

Ear Centering for Accurate Synthesis of Near-Field Head-Related Transfer Functions
Applied Sciences, 2022 The head-related transfer function (HRTF) is a major tool in spatial sound technology. The HRTF for a point source is defined as the ratio between the sound pressure at the ear position and the free-field sound pressure at a reference position.
