The sonic signature needs to keep the treble detail, but increase the frequencyspectrum and add a more full sound.
声音特色方面,要保持高音的细节,但增加频响宽度,增加更多的饱满的声音。

Studied two conditions of acoustic signals when it was single-phase gas and two-phase flow in the pipeline from soundspectrum, acoustic energy, peak frequency and amplitude.
Doppler effect can be demonstrated by manufactured device when the sound source is in circular motion. The frequencyspectrum is gained with chart spectrum analysis software.
