Well apparently one can hear one's own circulatory and nervous system: http://theresonator.blogspot.com/2007/04/john-cage-visits-an... > Cage entered the chamber expecting to hear silence, but as he wrote later, he "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."

I can attest to this. We have an anechoic chamber here at Michigan State and I've also been in the testing chamber at EV (Electro-Voice). Hearing the blood in your head and ears is quite odd, but the disorientation from not being able to place yourself in space is even stranger.

After reading this article, I immediately started to see if I could find one nearby and found out about the one at Michigan State. Would it be possible for me to go there and sit inside for a bit to experience this, even though I'm not a MSU student?

He mentioned that people generally can't be in there longer than 45 minutes. I would love to test that theory. Give me a desk, a laptop, and let me get to work. The most interesting thing would be whether or not my tinnitus is going to drive me insane or not :P

In a room this quiet I assume using keyboard will sound very loud.

I don't get why people can't spend more than 45 minutes in there. I understand that you begin to hear your heartbeat and so on, but surely anyone who is even slightly deaf (e.g. even from just prolonged listening to loud music) wouldn't hear these very low-decibel sounds? So it can't be the lack of sound, as a slightly hard of hearing person hears the noise floor drop out quite frequently. (Correct me if I'm wrong he…

The 45 minutes aspect is misleading. They haven't been using the room to test that, its just that no-one has spent longer than that so far.

Our title is (currently) "A room so quiet, no one can spend more than 45 minutes in it", and the Times Herald headline is even more specific: "A room so quiet no one can stand it for more than 45 minutes."

I'm wondering what it is they 'can't stand.' The article text is pretty vague. '“Your eyes don’t feel as comfortable in this room,” Orfield pointed out, adding that some visitors have had hallucinations during or after a spell in there. “You lose your touchstones.” Small wonder, then, that even Orfield spends no more than a half-hour at a time in the 99.99 percent soundproof anechoic chamber, and no one has lasted in there for more than 45 minutes.'

It doesn't match either my experience or my expectation, which is why I asked about it above. If someone had a silent computer to code on in there, could they crank out code for a couple of hours without nuisance, or would something bother them? If the latter, then what exactly would bother them?

Wouldn't they be the same thing, just "tuned" to block out different frequency ranges? I'm guessing the tuning is based on the material and shape of the foam, and thickness and material of the walls? It's all waves.

Sound waves and radio waves are not the same thing.

They're not the same things, no, but they obey the same wave mechanics, and due to the difference in propagation velocity, their wavelengths are actually very close. A wavelength of 3 meters is about 100 MHz in the RF world, and 1 kHz in audio terms.

That's why an RF anechoic chamber looks a lot like an acoustical anechoic chamber, and often sounds like one too.

Likewise, I'd like to try this... it seems cool as hell!

First of all, I'm seriously disappointed I can't test this because no computer is quiet enough. Second of all, I can't stand working in sound-proofed rooms. I much prefer working in an environment with (non-distracting) ambient sounds.

Look, the "45 minutes" thing is total clickbait. I've been in an anechoic chamber and it is a little disconcerting and weird to suddenly find yourself hearing nothing at all. I only spent a few minutes in there, and it's not uncomfortable at first, but it feels good to get out. It's basically just a feeling of disorientation.

But I have no doubt that, properly motivated, you could easily spend an hour in there. Hell, if I had access to one I'd go do it right now just for dumb internet bragging rights.
