Acoustic particle drop point simulation analysis method based on three-dimensional space

Abstract

The invention relates to the technical field of architectural acoustics, in particular to an acoustic particle drop point simulation analysis method based on a three-dimensional space. The method comprises the following steps: 1, picking up a sound source point A, a reflecting surface A and a seat surface B; 2, uniformly taking points B on the reflecting surface A; 3, connecting the point B with the sound source point A to obtain a line segment A, and extending the line segment A to obtain a line segment B; 4, mirroring the line segment B by taking the point B as a reference point and referring to the reflecting surface A to obtain a line segment C after mirroring; 5, the seat surface B is moved upwards by a certain distance, and an actual audience surface C of the human ear is obtained; 6, extending the line segment C, wherein the intersection point of the extension line of the line segment C and the actual audience surface C is a point C; and 7, drawing a circle by taking the point Cas the center of the circle to obtain a circle A, and taking the circle A as the drop point of the actual acoustic particle. The acoustic particle drop point simulation analysis method based on the three-dimensional space is convenient for determining the drop point of the sound source point A in the three-dimensional space and visually representing the drop point through different colors.

Description

technical field [0001] The invention relates to the technical field of architectural acoustics, in particular to a three-dimensional space-based simulation analysis method for acoustic particle drop points. Background technique [0002] Architectural acoustics is a science that studies the acoustic environment in buildings, including the propagation of sound in the building environment, the evaluation and control of sound, and is an integral part of building physics. It is used to control indoor sound quality and noise in the building environment to ensure good hearing condition. At present, the existing technology uses a two-dimensional method to simulate and analyze the falling point of the sound reflection in the building environment. The means are hand-drawn analysis, or analysis through CAD. Two-dimensional prediction cannot intuitively simulate and predict acoustic particles. The drop point leads to limitations and large errors in the simulation process, making it inc...

At present, the existing technology uses a two-dimensional method to simulate and analyze the falling point of the sound reflection in the building environment. The means are hand-drawn analysis, or analysis through CAD. Two-dimensional prediction cannot intuitively simulate and predict acoustic particles. The drop point leads to limitations and large errors in the simulation process, which is not easy to use
