Tangentially related
I once picked up my memory foam mattress and stood it up against one of the walls ... for cleaning the bed or whatever.
As I walked past the mattress I instantly noticed that the mattress is such a good absorber of audio waves that I could immediately notice a dip in ambient sound in the ear facing the mattress.
The room was already "silent" and this newly discovered lower limit of silence was pretty surprising to me physiologically.
- meindnoch 1y agoEveryone should try a real anechoic chamber once. The silence there is deafening.
- BobbyTables2 1y agoI shudder to think what tinnitus would sound like in an anechoic chamber…
- ilikepi 1y agoProbably similar to whatever its normal frequencies are for you, but perceptually louder. That seems to be my experience when I'm in a location with minimal background noise...
- larusso 1y agoDon‘t know if this is the same but I went to Death Valley on the Devil‘s Golf Course during summer. There was no wind no nothing. It was so damn silent. Wonder how that compares to an anechoic chamber now.
- 0_____0 1y agoHaving experienced both, it's very similar. Edit to add: I've been in an anechoic chamber and also the black rock desert, which is dead flat and thus has very little surface area oriented to reflect sound back at the listener, which makes it similar in that you don't experience environmental reflections. Devil's Golf Course has more "texture" to it but if you were quiet on a windless day I think the effect would be similar.
- cf100clunk 1y agoIf you are handy to an R&D lab that has a combo Faraday Cage/anechoic chamber you can have a nice experience free of RF and audio noise and stimulus. Even better if it is dimly lit in near-infrared. Even better-better if it has a tank of warm water with lots of epsom salts, although I've never been in a lab that had such a thing as a requirement.
- meindnoch 1y agoI'm skeptical of shielding yourself from RF noise having any detectable effect. Unless you have amalgam tooth fillings, that anecdotally can act as a crude diode, and demodulate strong enough AM signals.
- cf100clunk 1y agoThe goal is not to prove or disprove any affects on one's physiology, but simply to have the experience of being free of RF and audio for the sake of it.
- stouset 1y agoI think the point is that even saying the "experience" of being free of RF implies a perception which does not exist. Plus it's well-known that you don't really get the full experience of this unless you manage to shield yourself from neutrinos by surrounding yourself with sufficiently-dense proto-neutron stars.
- cf100clunk 1y agoNeutrinos, cosmic rays, and extraterrestrial subatomic particle streams are not considered RF, right?
- stouset 1y agoIf we're going out of our way to eliminate things that cause zero perceptual experience I don't see why you would exclude them.
