The Loudest Sound In The Quietest Room

In this video, I traveled to 3M to see how silence is science. Watch to see how the quietest room is used to study how sound waves move, which helps build the sound-damping products we use every day.

Who knows what I said in the reverberant chamber as I walked away from the camera?

[Ithenna]

That balloon pop was unexpectedly hilarious. It went from a gunshot loud reverberating bang in the first room to a pathetic tiny blip in the second.

I remember how weird it felt when I first tried noise cancelling headphones. Instantly felt like all my sinuses had plugged up!

Pretty sure the closest you could get to painting the quiest room, with the blackest paint, would be a sensory deprivation chamber

That weird empty pressure feeling also happens when you put your ear really close to an inflated balloon.

Walking away from the camera in the super echo chamber is such an incredible effect, I want to use that for a game or movie or something

That's fascinating. I've seen articles people have written saying that you can't spend more than a few minutes in one of those super quiet rooms without becoming really bothered and some people can go crazy from the crushing silence. It doesn't seem (to me) like it would be a big deal really just being in a real quiet room, just interesting and different.
Really interesting video - Thanks for this!

You should do more of these visits. I love it. And, 4:24 editor needs a raise

2:11 when you high asf and people talk around you

Just for reference, most gunshots are far louder than 143dB, generally ranging from 155+ all the way to almost 170, depending on caliber and barrel length. The 140 range is actually closer to what a suppressed (silenced) 5.56x45mm rifle would generally meter. Unless they're chambered for relatively small cartridges, "silenced" guns are usually quite loud, loud enough that hearing protection is still recommended. Hope this helps. Great video!

As someone with non stop tinnitus, i wonder how it would sound like being in that super quiet room

The anechoic chamber is sick. The room I mix in is anechoic but not THAT anechoic haha. Tracking vocals or electric guitar in there or mixing in it on high end monitors would be amazing. Once you get used to working in that kind of acoustic environment nothing comes close to it.

Also the reverb chamber perfectly demonstrated a fundamental property of recording; the further you place the mic from the source, the lower the ratio of source noise to room noise becomes

Hahaha at 3:29 "Puts safety glass on first" before blowing the air horn

Acoustics are so cool!

There’s actually a spot in my apartment complex, where you can hear a whisper about 25-30’ away in another specific area.

At 2:46 that balloon popping almost sounded just like a Gun shot! XD

happy to see that this channel has grown this much in few years, from homemade science experiments to visiting companies

The quiet of the desert is one of my favorite places. I think i would love a bedroom with some of that sounds absorbing stuff. Not so much that i hear my blood pumping through my body but just before that much would be great

The Worlds Quietest Room really takes “Quiet people have the loudest minds” to a whole new level.

I used to sort an archive room once. Many stalls filled with paper. Quietest room I’ve ever been at. Instead of “feeing of pressure” on my ears I rather felt that the pressure I wasn’t even aware of was finally gone, it was just heaven. Sorting the archive was quite meditative too, loved it. I would compare the feeling with what it feels like using a high refresh rate screen after you are used to 60Hz: the screen is just easier to look at and feels more natural, you feel the lack of pressure on the eyes you didn’t suspect.

That quite room is an *insane* place to visit! I'd like to go in there!
