Spatial Bandwidth of Diffuse Radiation in Distributed-mode Loudspeakers
نویسنده
چکیده
The degree to which radiation from a loudspeaker is diffuse may be quantified by a spatial correlation function normalised to the on-axis response. This is true for any loudspeaker type, including the distributed-mode loudspeaker (DML). However, because of the variation in material damping and design-related constraints, correlation commonly varies both with frequency and direction. A modified function, the offset spatial bandwidth of correlation function, is introduced as a means of describing diffuse performance and quantifying its variation over the radiation field.

Influence 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 کاملAn experimental evaluation of regular polyhedron loudspeakers as omnidirectional sources of sound
Multiple-driver dodecahedron loudspeakers are commonly used in room acoustics measurements as omnidirectional sources of sound. Yet they and other regular polyhedron loudspeakers become “multidirectional” above their omnidirectional cutoff frequencies often near 1 kHz . Because these cutoff frequencies normally fall within common measurement bandwidths, one might question whether anything is re...
متن کاملLow frequency room excitation using Distributed Mode Loudspeakers
Conventional pistonic loudspeakers excite the modes of an enclosed sound field in such a way as to introduce modal artefacts which may be problematic for listeners to high-quality reproduced sound [1]. Their amelioration may involve the use of highly space-consumptive passive absorptive devices or active control techniques [eg 2,3,4]. Other approaches have concentrated on the design of the driv...
متن کاملTransient modal radiation of axisymmetric sources: application to loudspeakers
For high amplitudes of vibrations, loudspeakers are subject to nonlinear phenomena that are responsible for audible distortions. In order to describe the complex dynamics of the system, the displacement field as well as the radiated sound pressure must be expressed in the time-domain. Thus the present study proposes a transient model of the acoustic radiation of axisymmetric structures. The pre...
متن کاملEvaluation of Spatial-Temporal Variations of Incoming Solar Radiation in Kermanshah Province Using "Liu and Jordan" Model
The aim of this study was to provide a reliable estimate of the amount of solar radiation in Kermanshah province by using “Liu and Jordan” model in order to develop solar sites. The amount of atmospheric elimination in each month was calculated using an index called clearness index () and the results were applied on different slopes, aspects and heights. Then, according to the obtained results,...
