Embodiment Construction
[0029] The drawings are for illustrative purposes only, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, some parts in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product;
[0030] For those skilled in the art, it is understandable that some well-known structures and descriptions thereof may be omitted in the drawings. The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0031] A method for simulating indoor and outdoor sound propagation that combines sound ray tracking and beam tracking. First, the outdoor space is divided into triangular prism-shaped subspaces according to the perimeter boundary of the building and the boundary of the calculation area, such as figure 1 As shown, the spatial subdivision results can be used as the basis for the accelerated acoustic beam tracking ...
