Hangzhou Aihua Sound Power Measurement System (Sound Intensity Method)
Hangzhou Aihua Sound Power Measurement System (Sound Intensity Method)
Product details
Composed of AWA8450 sound intensity probe, AWA6290M+dual channel acoustic analyzer, and sound intensity analysis software, it complies with GB/T 17561 and IEC 1043 standards. A sound intensity measuring instrument is an instrument that measures the component of sound intensity in a certain direction in an air medium. It can measure the sound power level of the sound source on site by measuring the sound intensity, and provide real-time octave and one-third octave frequency spectrum analysis results of sound intensity and sound pressure, as well as sound intensity intensity maps. By measuring the sound intensity at multiple points, the distribution of sound energy flow intensity on a certain plane near the sound source can be obtained to study the radiation characteristics of the sound source.
