声强测量作为新的测试手段在噪声控制领域中应用愈来愈广。为了提高实验效率,扩大应用范围,本文实现了声强测量的计算机控制。编制了测算声功率及测绘声强三维分布图的应用软件。在此基础上,通过实验说明了声强测量在测量声功率及鉴别噪声源方面的应用及其优点。 Sound intensity measurement as a new test means more and more widely used in the field of noise control. In order to improve the experimental efficiency and expand the scope of application, this paper realizes the computer control of sound intensity measurement. The application software for calculating the three-dimensional distribution of sound power and mapping sound intensity is compiled. On this basis, the application of the sound intensity measurement in the measurement of sound power and identification of the noise source and its advantages are illustrated experimentally.
