Embodiment Construction

[0057] The internal configuration of an acoustic design support device according to an embodiment of the present invention will now be described with reference to FIG. 1 . FIG. 1 shows the internal configuration of the acoustic design support device and the data structure of the data of the basic shape of the conference facility in this embodiment. The acoustic design support device 1 supports selection or installation of acoustic equipment such as speakers in conference facilities such as concert halls or conference centers. The sound design support device 1 simulates a sound field when outputting sound and displays the simulation result. Such as Figure 1A As shown, the sound design support apparatus 1 includes a computer or the like and a program installed on the computer or stored in a fixed memory. Specifically, the sound design support device 1 includes an operation unit 102 , a CPU 103 , an external storage device 104 , a memory 105 , and an audio output device 106 , a...

Abstract

In an acoustic design support apparatus, a speaker selection supporter selects a desired speaker as a candidate for use in a given space based on shape information representing a shape of the space. A speaker mounting angle optimizer calculates an optimal mounting direction of the selected speaker by selecting a mounting direction pattern which minimizes a degree of variation among sound pressure levels at a plurality of positions on a sound receiving surface defined in the space. An acoustic parameter calculator calculates a variety of acoustic parameters at sound receiving points within the space based on both of the shape information of the space and the optimal mounting direction of the speaker.

Description

technical field [0001] The present invention relates to an apparatus and program for supporting acoustic design of an acoustic facility. Background technique [0002] Various design support devices or programs have been proposed for use in relation to audio equipment in conference facilities such as concert halls or conference centers (see Patent Documents 1 to 4). Preferably, these devices or programs display, on a display device, speaker sounds located at seats or the like receiving sounds from speakers installed in concert halls, etc., in accordance with the characteristics of the selected sound system before the sound devices are installed at a location Acoustic characteristics of the receiving surface (or sound receiving surface for short), so that the displayed acoustic characteristics can be reflected in the selection of the sound system or in the acoustic adjustment of the position. [0003] Patent Document 1 describes an apparatus that generates impulse response da...
