Local sound field reproduction using two closely spaced loudspeakers
When only two loudspeakers are used for the reproduction of sound for a single listener, time domain simulations show that it is advantageous that the two loudspeakers are very close together. The sound field reproduced by two loudspeakers that span 10 degrees as seen by the listener is simpler, and locally more similar to the sound field generated by a real sound source, than that reproduced b...
متن کاملSound Field Reproduction Employing Non-Omnidirectional Loudspeakers
In this paper we treat sound field reproduction via circular distributions of loudspeakers. The general formulation of the approach has been recently published by the authors. In this contribution, we concentrate on the employment of secondary sources (i.e. loudspeakers) whose spatio-temporal transfer function is not omnidirectional. The presented approach allows to treat each spatial mode of t...
متن کامل2.5D Sound Field Reproduction Using Higher Order Loudspeakers
Using 3-Dimensional (3D) sound sources as secondary sources to 2-Dimensional (2D) sound field reproduction, it is termed 2.5-Dimensional (2.5D) sound field reproduction which is currently drawing broad interest in acoustic signal processing. In this paper we propose a method to reproduce a 2D sound field, using a circular array of 3D High Order (HO) loudspeakers, which provides a mode matching ...
متن کاملReproduction of a plane-wave sound field using an array of loudspeakers
Reproduction of a sound field is a fundamental problem in acoustic signal processing. In this paper, we use a spherical harmonics analysis to derive performance bounds on how well an array of loudspeakers can recreate a three-dimensional (3-D) plane-wave sound field within a spherical region of space. Specifically, we develop a relationship between the number of loudspeakers, the size of the re...
متن کاملThe Realistic-Reverberation Sensation in 3-D Acoustic Sound Field Reproduction with Parametric Loudspeakers and Indirect Electrodynamic Loudspeakers
In the field of virtual reality, mixed reality (MR) system has recently been drawing attention as a technology to experience the virtual world by superimposing the computer graphics (CG) objects in real world. The technologies to reproduce 3-dimensional (3-D) acoustic sound fields in conjunction with MR can especially experience a higher realistic sensation than the conventional MR. Parametric ...
