This reminds me of the story of how composer John Cage was inspired to write his piece 4′33″ [1]:

'In 1951, Cage visited the anechoic chamber at Harvard University. An anechoic chamber is a room designed in such a way that the walls, ceiling and floor absorb all sounds made in the room, rather than reflecting them as echoes. Such a chamber is also externally sound-proofed. Cage entered the chamber expecting to hear silence, but he wrote later, "I heard two sounds, one high and one low. When I described them to the engineer in charge, he informed me that the high one was my nervous system in operation, the low one my blood in circulation." Cage had gone to a place where he expected total silence, and yet heard sound. "Until I die there will be sounds. And they will continue following my death. One need not fear about the future of music." The realization as he saw it of the impossibility of silence led to the composition of 4′33″.'

I did read about those, a "challenge" is how long you can stay in there before going mad - I think the longest one lasted for 45 minutes.

I'd like to experience that sometime, like, true silence. Have to say that my current house is very quiet (especially compared to my previous one), but there's still some background noise from outside, neighbours, the ventilation, etc. Should get a decibel meter sometime.

Anyway yes, sensory deprivation is weird.

The 45 minutes is apparently a myth. You can view an interesting video on ultra-quiet anechoic chambers in this veritasium video [1].
