An overview of directivity control methods of the parametric array loudspeaker
A sound reproduction system usually consists of several types of loudspeakers to cater to sophisticated applications. The directivity of a loudspeaker is a measure of its efficiency in sending sounds to a particular direction instead of all directions. Demand to control the directivity of a sound reproduction system is gaining momentumwith many new designs of directional loudspeakers, including...
متن کاملControlling the perceived distance of an auditory object by manipulation of loudspeaker directivity.
This work presents a method to control the perceived distance of an auditory object by changing the directivity pattern of a loudspeaker and consequently the direct-to-reverberant ratio at the listening spot. Control of the directivity pattern is achieved by beamforming using a compact multi-driver loudspeaker unit. A small-sized cubic array consisting of six drivers is assembled, and per drive...
متن کاملInfluence of model parameter variability on the directivity filters of compact loudspeaker arrays
2845 Sound directivity control is made possible by a compact array of independently driven loudspeakers. Recently, a control system for such a multi-channel source based on its acoustic radiation modes has been proposed. These modes form an orthogonal set of velocity patterns on the source surface, and emerge from the eigendecomposition of a free-field radiation operator that depends on frequen...
متن کاملMultichannel level alignment, part III: The effects of loudspeaker directivity and reproduction bandwidth
The correct level alignment of multichannel reproduction systems is critical to the quality of the reproduction. This, the third paper discusses the results of three experiments employing the nine test signals discussed in paper I. Experiments employing six subjects using the method of adjustment have been conducted in a standard listening rooms using a symmetrical loudspeaker set-up. The influ...
متن کاملThe Theory of Maximally Flat Loudspeaker Systems
A convenient mathematical formulation is given for the absolute lowfrequency response of an electrodynamic direct radiator loudspeaker mounted in a vented or unvented enclosure. The combined effects of speaker Q (ratio of reactance to resistance), enclosure size, and enclosure tuning are shown to control the convergence of the response curve towards ts asymptotic value. Mathematical criteria ar...
