Zusammenfassung: | The invention relates to an acoustic measurement system and method, the system comprises an acoustic test box, an acoustic sensor measurement module, an industrial personal computer and an acoustic analysis module, the acoustic sensor measurement module is used for converting an acoustic vibration signal of a to-be-detected product into an electric signal; the industrial personal computer comprises a data acquisition card, and the data acquisition card acquires an electric signal and digitalizes the electric signal to be imported into the industrial personal computer; and the acoustic analysis module is used for correcting the measurement curve of the product to be detected, so that the measurement curve approaches to the measurement result under the ideal measurement environment condition. The numerical value measured in the sound field environment in the acoustic test box can be close to the data measured in the anechoic chamber through an acoustic algorithm, the test precision is high, the problems of high |
