Exotic compact objects (ECOs) produce the same initial event detected by LIGO-Virgo collabo-ration as classical black holes (BHs), but various quantum gravity models feature the different following echoes. In particular, we investigate the echoes from the fluctuation-dissipation theorem [1, 2], which changes the dispersion relationship near the (would-be) horizon and results in a Boltzmann reflective boundary. We derive correspondent quasi-normal modes (QNMs) analytically. Further, wemodel the analytical and numerical echoes in the real time, which are consistent with each other. Last, we show that the superradiance is highly suppressed in the theorem.
