TL;DR
This paper investigates the potential detectability of small black holes passing through Earth by analyzing their energy losses and the resulting acoustic signals, focusing on Cherenkov radiation and sound wave conversion.
Contribution
It introduces a detailed analysis of acoustic signals generated by small black holes traversing Earth, highlighting detection possibilities via modern acoustic detectors.
Findings
Cherenkov-type sound radiation is a dominant signal.
Black hole radiation can convert into detectable sound waves.
Potential for acoustic detection of small black holes passing through Earth.
Abstract
We examine the energy losses of a small black hole passing through the Earth, and in particular, the excitations created in the frequency range accessible to modern acoustic detectors. The dominating contributions to the effect are due to the coherent sound radiation of the Cherenkov type and to the conversion of black hole radiation into sound waves.
