Acoustic contrast, planarity and robustness of sound zone methods using a circular loudspeaker array.
Since the mid 1990s, acoustics research has been undertaken relating to the sound zone problem-using loudspeakers to deliver a region of high sound pressure while simultaneously creating an area where the sound is suppressed-in order to facilitate independent listening within the same acoustic enclosure. The published solutions to the sound zone problem are derived from areas such as wave field...
متن کاملAcoustic contrast control in an arc-shaped area using a linear loudspeaker array.
This paper proposes a method of creating acoustic contrast control in an arc-shaped area using a linear loudspeaker array. The boundary of the arc-shaped area is treated as the envelope of the tangent lines that can be formed by manipulating the phase profile of the loudspeakers in the array. When compared with the existing acoustic contrast control method, the proposed method is able to genera...
متن کاملBeam Dithering: Acoustic Feedback Control Using a Modulated-Directivity Loudspeaker Array
Similar expressions hold for b n. To achieve the modulation, the array is weighted with the time-varying linear combination c n = (t)a n + f1 ? (t)gb n (5) where (t) is a smoothly varying function having an amplitude ranging from zero to one and a period much less than the reverberation time of the acoustic enclosure. This time-varying linear combination results in a time-varying beamwidth of r...
متن کاملImplementing Ambisonics on a 48 Channel Circular Loudspeaker Array
This contribution describes an implementation of near field coding higher order Ambisonics on an existing circular array of 48 loudspeakers. Static and moving sources can be reproduced with a variable Ambisonics order and variable number of loudspeakers. Informal listening tests were performed to evaluate the influence of Ambisonics order and loudspeaker number on the perception quality and loc...
متن کاملA Circular Array for Plane-Wave Synthesis
We analyze a circular array of electric line sources for generating a uniform plane wave in the interior region of the array. Identical results for the synthesized element weightings are obtained using matrix inversion or a Fourier series technique. A physical optics approximation for the element weightings is also presented, hut it yields a much poorer result for the synthesized field. The ang...
