Audio Equipment Testing

Sound refers to other sounds besides human language and music, including the sounds of the natural environment, the sounds of animals, the sounds of machine tools, and various sounds emitted by human movements. Audio probably includes a set of power amplifiers, peripheral equipment (including compressors, effectors, equalizers, VCDs, DVDs, etc.), speakers, mixers, microphones, display equipment, etc. Among them, speakers are sound output devices, speakers, subwoofers, etc. A speaker box includes three types of speakers: high, low and medium.

The purpose of audio testing is to evaluate the experience consumers experience when using the speaker's playback function, and to evaluate the related attributes of audio quality through a series of representative use case scenarios.
