给出了声黑洞中线性化量子涨落的反反应方程。视界附近的解，在一个降维范围内得到，表明声黑洞不同于史瓦西黑洞，当它们辐射声子时温度会降低。它们与近乎极端的Reissner-Nordström黑洞有着惊人的相似之处。
The backreaction equations for the linearized quantum fluctuations in an acoustic black hole are given. The solution near the horizon, obtained within a dimensional reduction, indicates that acoustic black holes, unlike Schwarzschild ones, get cooler as they radiate phonons. They show remarkable analogies with near-extremal Reissner-Nordström black holes.
