Abstract

The invention discloses a method for detecting an indoor sound reinforcement device. The method comprises a first step that a DSP processing module controls a controllable output matrix to output a test signal to a speaker array; a second step that a sound pick-up array collects an indoor sound signal and sends the indoor sound signal to an audio analysis module; a third step that the audio analysis module analyzes loudness, phase, frequency response and distortion factor of the sound signal; a fourth step that the DSP processing module calculates a balance degree of the sound field in an indoor environment according to the loudness, calculates delay according to the phase difference, and calculates the matching of the sound built environment and the sound reinforcement device according to the frequency response and the distortion factor; and a fifth step that test results are outputted. The automatic detection function for the indoor sound reinforcement device can be used for bringing standardized and quantified acceptance criteria to acceptance of project and greatly simplifying the acceptance process. The invention is applicable to all indoor sound reinforcement systems.

Description

[0001] technical field [0002] The invention relates to the field of sound processing and amplification, in particular to a detection method for indoor sound reinforcement equipment with a relatively high degree of automation, which is applied to indoor environments such as classrooms and meeting places. Background technique [0003] When installing a sound reinforcement system in classrooms and conferences, the installation effect is closely related to the indoor sound environment and the audio characteristics of the sound reinforcement equipment. Therefore, in the past, to ensure the installation effect, professional sound engineers had to go through complicated debugging after installation. use, and the indoor sound reinforcement equipment involved in the present invention does not need manual inspection after installation, the system will automatically detect the installation effect, and automatically prompt unreasonable equipment. In addition, many parameters in the ac...
