      i don’t think so, they basically have a very tight bean of sound that goes straight, and then count the time it takes to return. i think this only counts the first bounce, as there would be exponentially more after the first, and they would also be super quiet. (see the thought emporium’s video on this, and btw, im very much just saying my thoughts with 0 research)
