[Cthulhu_]

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].
