摘要
The results of the development and experimental verification of a system for obtaining and processing diversity acoustic noise control data are presented. The system is implemented using the LabView G graphical programming language. The length of the measured realization is determined by the ratio of the sample size to the sampling frequency. The number of measurements of each sound signal is determined by the ratio of the analysis time to the length of the measured realization. The measured audio signal implementation in the form of 40,000 16-bit binary numbers is processed using the fast Fourier transform. The result is a discrete spectrum of the audio signal in the range from 0 to 20 KHz with a step of 1 Hz. The results of the system check using a laboratory acoustic chamber and a noise shield are presented. The advantages and disadvantages of the system are formulated.
