Our local species of cicada has been measured at 150 decibels - bloody loud. So I imagine if the bedroom walls were bugged next to one's pillow, hearing damage is plausible. It's consistent with a "blaring, grinding" noise and the cricket's internal proximity sensor that caused the sound to disappear when the occupant moved away from the vicinity of the wall. https://www.abc.net.au/news/2017-09-15/us-investigates-mystery-acoustic-attacks-on-diplomats-in-cuba/8950568 https://www.abc.net.au/news/2017-09-15/us-investigates-myste...
