声学测试环境下环境修正值K_2的确定方法

Discussion of Determinative Method of K_2 Modulus under Acoustics Test Environment

噪声源的声功率是噪声测量的一个重要指标,本文通过针对噪声源测量方法的介绍,对环境修正值K2的确定方法进行了分析和探讨。实践证明,只要准确求出非标准测试室的环境修正值K2,在其里面进行声功率的测量是可行的。

Sound power is a very important index of the noise measuring. Showing the measuring method of the sound power, the paper analyzes end discusses the determinative method of K2 modulus. The practice shows, if the K2 modulus for a non-standard testing room can be determined correctly, then the sound power in this acoustics testing room can be measured.
