I can't say I do. I'd like to figure out why, though.

[ This place was puzzling. Perhaps there was a scientific explanation behind it? This place calls to Senku's mind anechoic chambers, like the quietest room in the world back at Orfield Laboratories. However... To be unable to hear your own voice, nor someone else adds another layer to this. ]

My first thought is a large scale anechoic chamber. But there's some sort of deafening property around here as well.
