Environmental Noise Source Identification Based on Sound Pressure and Sound Intensity Integrating Techniques

Abstract:

In view of the traditional methods can not accurately identify the far field of the problem of sound source location,Sound pressure and sound intensity combination technique is proposed for identifying environmental noise source. Using the method of sound pressure can test the size of the noise sound pressure and sound intensity method can identify the noise source bearing characteristics identify the noise source. The technology of this noise identification is applied to identify Noise of boundary of a factory and then finds out the main noise source. Test results showed that: Causing the plant boundary noise source are the 3rd, 5th, 6th, 7th sound source, therefore the solution of reducing noise at boundary is developed.
