The thermoacoustic phenomenon is a positive excitement betWeen lieat release and acousticoscillation.
热声现象是放热过程和声学脉动之间的一种正向的相互激励。

It is shown that the flow instability with high frequency belongs to acousticoscillation and the flow instability with low frequency is density wave instability.
高频脉动属于声波型脉动，低频脉动属于密度波型脉动。

Subsets of frequency response are physical microphonics, electronic ringing and oscillation, and acoustic ringing.
