Problems solved by technology

[0003] At present, the manual method is usually used to configure the parameters of the audio analyzer and calibrate the working parameters of the audio analyzer, but the manual method has the problems of cumbersome calling process, low efficiency, and non-professionals are easy to make mistakes in parameter configuration
[0004] In addition, using the software that comes with the existing audio analysis instrument for testing, the test data needs to be manually exported, and when repeated tests are performed under the same test conditions, the previous data needs to be manually deleted, which is likely to cause confusion in the test data. Easily influenced by testers, poor test accuracy

Abstract

The invention discloses a microphone performance test method, test management equipment and a test system. The test management equipment is in communication connection with an audio analysis device and a simulation nozzle; the audio analysis device outputs a sound signal to a microphone to be tested through the simulation nozzle. The method comprises the steps: providing a window used for settinga first test parameter, wherein the first test parameter comprises a sweep amplitude sound pressure level range of a first target sound signal; selecting a sweep amplitude sound pressure level of thefirst target sound signal from the sweep amplitude sound pressure level range; determining a working amplitude of the audio analysis device according to the swept-amplitude sound pressure level basedon a preset mapping relation between the sound pressure level and the amplitude, and configuring the audio analysis device according to the working amplitude; calling the audio analysis device to workso as to emit a first target sound signal to a to-be-tested microphone through the simulation nozzle; and enabling the audio analysis device to generate a first analysis result according to the firsttarget sound signal and a signal picked up by the to-be-tested microphone.

Description

technical field [0001] The present invention relates to the technical field of microphone testing, and more specifically, to a microphone performance testing method, a testing management device and a testing system. Background technique [0002] When testing the total harmonic distortion rate and high sound pressure impact performance of the microphone, it is necessary to call an audio analyzer (Audio Precision, AP) for testing. Through the configuration of the audio analyzer, the sweep, frequency sweep, high Tests of different items such as sound pressure impact. [0003] At present, the parameters of the audio analyzer are usually configured manually and the working parameters of the audio analyzer are calibrated, but the manual method has the problems of cumbersome calling process, low efficiency, and easy mistakes in parameter configuration by non-professionals. [0004] In addition, using the software that comes with the existing audio analysis instrument for testing, ...
