摘要

一个复杂的声源可以用一系列自由声速声源来表示。声场中某一位置的声压可以通过声源自由声速强度及其各自传递函数的乘积和来预测。这些传递函数将声场中的声压与声源强度联系起来。在本研究中，在自由场位置测量声压，然后通过反求法确定声自由速度源强度。将该方法应用于具有高指向性的实验室源的表征。然后证明了源可以用来预测引入的阻挡源与接收器的屏障的插入损耗。

Prediction of sound radiation using reconstructed acoustic free velocity sources

A complicated source can be represented by a series of acoustic free velocity sources. The sound pressure at a position in the field can be predicted by summing the products of the acoustic free velocity source strengths and their respective transfer functions. These transfer functions relate the sound pressure in the field to the acoustic source strength. In this research, the sound pressure is measured at positions in the free field and then is used to determine the acoustic free velocity source strengths via an inverse method. The approach is applied to characterize a laboratory source with high directivity. It is then demonstrated that the sources can be used to predict the insertion loss of a barrier introduced to block the source from the receiver.

期刊介绍： Noise and Health is the only International Journal devoted to research on all aspects of noise and its effects on human health. An inter-disciplinary journal for all professions concerned with auditory and non-auditory effects of occupational, environmental, and leisure noise. It aims to provide a forum for presentation of novel research material on a broad range of topics associated with noise pollution, its control and its detrimental effects on hearing and health. It will cover issues from basic experimental science through clinical evaluation and management, technical aspects of noise reduction systems and solutions to environmental issues relating to social and public health policy.
