Research on the Ventilator Noise Sound Intensity Measure

Abstract:

Noise measurement is the important means on the noise monitoring, evaluation and control.At present the error of sound pressure method widely used is larger. It adopts the method of double microphone in the method of sound intensity measurement,and uses acoustic pressure gradient change to approximately equal the particle vibration velocity, spectrum density function is obtained by using sound intensity analyzer,it computes integral for Spectrum density function that are sound intensity.In this paper, by measuring sound intensity of ventilator and comparing the numerical results and experimental results, it confirmed that the method is high precision, has practical application value.
