System for selecting speaker locations in an audio system

摘要

A system is provided for configuring an audio system for a given space. The system may statistically analyze potential configurations of the audio system to configure the audio system. The potential configurations may include positions of the loudspeakers, numbers of loudspeakers, types of loudspeakers, listening positions, correction factors, or any combination thereof. The statistical analysis may indicate at least one metric of the potential configuration including indicating consistency of predicted transfer functions, flatness of the predicted transfer functions, differences in overall sound pressure level from seat to seat for the predicted transfer functions, efficiency of the predicted transfer functions, or the output of predicted transfer functions. The system also provides a methodology for selecting loudspeaker locations, the number of loudspeakers, the types of loudspeakers, correction factors, listening positions, or a combination of these schemes in an audio system that has a single listening position or multiple listening positions.

主权项

1. An audio system comprising at least one loudspeaker, at least one loudspeaker location for the loudspeaker being selected based on a method for selecting the at least one loudspeaker location from potential loudspeaker locations, the method comprising:
determining the potential loudspeaker locations; generating acoustic signals from at least one loudspeaker placed at the potential loudspeaker locations; recording transfer functions at a plurality of listening positions for the generated acoustic signals; modifying the transfer functions based on the potential loudspeaker locations so that predicted transfer functions are generated at at least two of the plurality of listening positions for each of the potential loudspeaker locations, the predicted transfer functions representing simulations for the potential loudspeaker locations; accessing a criterion by which to statistically analyze the predicted transfer functions, statistically analyzing using the criterion across at least one frequency of the predicted transfer functions for the at least two of the plurality of listening positions; and selecting at least one loudspeaker location to improve for the criterion at the at least two of the plurality of listening positions based on the statistical analysis, where the criterion is flatness, consistency, efficiency, and smoothness.
