sound power of a source

基本解释

The Korean scientists, however, want to harness a different kind of power source: sound waves.
然而，韩国科学家想驾驭一种不同类型的能量源，那就是声波。
A measuring method for two microphone cross spectrum sound intensity suits for the determination of acoustical power of a machine and the identification of sound source on the spot.
双传声器互谱声强测量法适用于现场测量机器的声功率和进行声源识别。
The results show that the sound power measured by scanning along a given scanning path with a sound intensity probe can approximate the actual sound power of noise source effectively.
当人工执行扫描测量，实际扫描路径存在一定的偏移时，只要扫描偏移值在一定的容差范围内，所测得的声源声功率仍然能够取得较好的结果。
