An analytical approach to 2.5D sound field reproduction employing linear distributions of non-omnidirectional loudspeakers
Jens Ahrens,Sascha Spors +1 more
TL;DR: An analytical approach targeting the physical reproduction of sound fields by means of linear distributions of loudspeakers, which does not compensate for loudspeaker properties which deviate from certain assumptions but allows for the explicit consideration of these properties within some limits which are outlined.

Localized sound reproduction using circular loudspeaker array based on acoustic evanescent wave
TL;DR: Computer simulation results show that the proposed evanescent wave reproduction method achieves faster distance attenuation than a point source and reduces the number of loudspeakers to less than that of the linear loudspeaker array.

Sound radiation of a vibrating elastically supported circular plate embedded into a flat screen revisited using the Zernike circle polynomials
TL;DR: In this article, an elastically supported thin circular plate is excited asymmetrically, and the acoustic power is expressed in terms of the modal impedance coefficients without numerical integration and with arbitrary precision in a wide low frequency band.

Spatial accuracy of binaural synthesis from rigid spherical microphone array recordings
TL;DR: In this paper, the authors evaluated the spatial accuracy in binaural signals synthesized from the recordings of RSMAs with different number of microphones using the model of a human head and found that the synthesis of spectral cues is accurate up to a maximum frequency determined by the number of sensors.
Journal ArticleDOI
Optimization of the directivity in binaural sound reproduction beamforming
TL;DR: This work presents a more general mathematical framework than previously presented for the incorporation of HRTFs in the weight function, which allows the optimization of the Weight function using an averaged maximum-directivity criterion under the condition that the HRTFS are already incorporated.
