okay so I am going to start talking then I am walking away from the camera and you will notice that as I keep talking it gets more and more muffled the further I get away from the camera until eventually you probably cannot hear what I am saying the further I went to be from the camera you can not hear what I'm saying it's echo that's heard .. it's the sound waves that ........ ( and maybe one more statement idk )

[@DTLRR]

Haha 😂. I lost it. And when you reached the end of the room, the point where you appeared to touch the wall, the sentences you said from that point literally seemed hilarious. I couldn't stop laughing. Whatever you were saying, I just heard Grrahhh! Grahhh! Ghoghh!. 😂

[@taranciucgabrielradu]

Absolute silence is a lot more silent than you can think it is if you've never experienced it Even if you're alone in the middle of a field in the middle of nowhere, you still have some sounds going on around you. Air brushing against things makes sound, and overall just the air carrying some sound waves even tho they might be at 1dB by the time they get to your ear, it's still "something" This room gives you absolutely nothing, you can only hear the sounds you make

[@henrybialik8333]

I use to work in a quiet rooms. First time, I got sick after about 5 mins and puked. After awhile I could spend up to 45mins, but it never really felt good. Yes you could hear your heart beat inside your ears if you concentrated on it.

[@MatVeiQaaa]

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.

[@claytonharting9899]

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

[@mvxenda]

Any reverb device/plugin can do the trick just by adjusting mix/decay parameters. Btw, you can also sample the sound of the balloon popping in this reverb room and use it as an impulse response in any sort of sound convolver s, so that you can exactly replicate the character of the reverb this room has. There are many possibilities and ways to do it digitally

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

[@alexandreventuraveado4150]

Perfect! I worked in the oil industry and entered countless bizarre environments: gas spheres, storage tanks, the inside of the legs of sea platforms. It's incredible, impressive, how the sound behaves. In the sphere, reverberation is continuous and difficult to minimize.

[@BenjaminRay]

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

[@mickyr171]

As you put your ear next to an inflated balloon you block all direct pressure waves traveling through the air and only intersect the pressure waves traveling through the balloon, its different then the waves in that room which is designed to essentially collapse waves traveling through the air through de constructive interference patterns and more or less only allow you to hear your voice through the vibrations of your own bone structure hence why he said it feels like he's putting his fingers in his ears.

[@santhoshsam40]

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

[@GetMoGaming]

I think that "deafening silence" feeling is caused by your brain's expectation to hear reflections from the environment, and not hearing it. That's the VOID you feel. It's a kind of claustrophobia, induced by the abnormal surroundings.

[@iWillRun_]

it is mainly because our ear drums are constantly hit with sounds waves but when we are in silence with no sound there is severe pressure on ear drums that they are not accustomed to, we have a silent room in one of our acoustic lab and if we stay silent for few hours it can case permanent ear damage

[@GetMoGaming]

@@iWillRun_ I can't believe that at all. The net pressure on the eardrum is constantly shifting. That's why we have Eustachian tubes, to relieve that pressure. Why would there be MORE net pressure than normal in silence? It makes no sense. Like, if that were the case, why doesn't flying in a plane (large altitude shifts) or deep diving make you deaf? That's a huge pressure bias. But again, why would it create a pressure bias anyway? Why wouldn't that happen if you wear noise-cancelling headphones? Further, there is always vibrations at the eardrum, due to body noise. Nope, no sense at all, from any angle.

[@shootinbruin3614]

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!

[@darrylpioch2055]

Gunshots are extremely different from oscillating sound waves that comprise the vast majority of what we hear though. The main bang of a gunshot is a shockwave, which is a single positive (increasing) pressure inflection followed by a single low pressure inflection (or even a brief vacuum if it's above 194dB spl). Normal sound waves are oscillating air molecules that correspond to rapid higher and lower pressure inflections that go on for extended periods of time compared to a shockwave. If that whistile really is 143dB SPL (which I kinda doubt but maybe) at the frequency it's pumping out it would instantly permanently damage your hearing. Also it depends on the distance, since every time you double the distance from the source you lose 6.02dB SPL

[@shootinbruin3614]

@@darrylpioch2055 While a gunshot is indeed an impulse noise, it holds its peak anywhere from 3-5 milliseconds. Much like how the whistle can be blown for longer or shorter at relatively similar intensities, a gunshot can hold its peak SPL for varying durations, dependent mainly on powder charge, burn rate, and muzzle device. This is why a .308 Winchester and a .300 Win Mag rifle can both meter at ~168dB peak even though anyone present will tell you that the latter sounds significantly louder. Most gunshot testing in the U.S. is conducted by its domestic suppressor industry, and is typically done in accordance with the Army Research Laboratory's MIL-STD-1474D. This specifies that the microphone be fixed 1M to the right of the muzzle, although more and more companies and independent testers are also metering at the shooter's right ear as suppressor development has shifted to focusing on the benefits to the user rather than purely on downrange sound signature. The shockwave propagated by a supersonic bullet is itself around 140dB and--along with bullet impact--becomes the predominant sound at the target location. Past a certain point, attempting to get a centerfire rifle "quieter" becomes an exercise in diminishing returns.

[@darrylpioch2055]

@@shootinbruin3614 1m to the right of the muzzle makes sense for a definitive metering. Speakers and subwoofers are usually spl metered at 1m with the mic directly aimed at the cabinet. I didn't know gunshots hold such a long peak but that would make sense since there's still chamber pressure after the bullet leaves the end of the barrel. Maybe there's more physics to it I'm not too educated on Also side note: the human ear has very different sensitivities at different frequencies and they also react differently to impulses/shockwaves. There's a peak plateu from around 2KHz to 5KHz and under 2K there's a gradual roll off that gets more dramatic the lower you go. So basically we don't hear anywhere close to flat. An example of it is people can give out 160dB+ bass demos at a car audio competition all day and not suffer any hearing loss. To the point where the physical pain is way more uncomfortable than the ear pain. At subsonic frequencies that 160dB is no big deal. If however that 160dB was at 3KHz, it would instantly and permanently make a person deaf. Same for the front row of a concert; if you're at the front but there's no full range fills anywere near you you're probably good, but when you're in front of a stack of subs with a full range cab on top pointed straight at you from a few feet away that's a big big problem lol

Care to explain?? What happened

[@RB9522]

At Firestone's research lab, we had an anechoic chamber big enough to test semi-tractors on a dynamometer. Working in the chamber by yourself was disorienting when nothing was in it. Workers often brought a portable radio and put it in the corner so it would keep them oriented. During setups, it was so quiet that you could hear your breathing, heart pumping, bones and joints cracking, and other body sounds. We used the chamber to measure tire noise when the tractor was running at low and high speeds. A truck can emit upwards of 1 KW of sound power. In other words, more than 1 horsepower was used (wasted) just to produce sound!

[@TimpBizkit]

I'm surprised because I'm sure a set of 1kw loudspeakers with high efficiency horns would be louder than the truck. Is that 1kw acoustic output - which is nearly 140dB from a meter away in all directions - or an inefficient loss of energy of which some is converted to sound and the rest to heat?

[@JackMaslovLive]

I crawled through a maintenance hatch into one of the pulping vats - a vertically oriented cylinder maybe 15 ft in dia & 30 ft high, lined with some kind of ceramic tile.

But the real question is: If a tree fell in the room and there was no one around to hear it... Would it still make noise...?

[@mikejones-vd3fg]

yeah of course, noise are just pressaure waves from the atoms interacting when it falls, the atoms will still itnerct and create those preasure waves if we were there or not, thats just one form of sense though, it could be producing other forms , gravitiational waves, quantum fluctuations, no matter how small it could be making all kinds of noise we arent able to pick up. So the answer tothe question is yes, its would make a noise, and is probably making more noises we cant hear.

@@mikejones-vd3fg ok, but it's just a joke 👍

More importantly, if a tree fell in the room, and there was no one around to hear it, and it crushed a mime, would anyone care?

[@magnumsalyer]

Yesterday, had a stomach full of KFC , Then I watched this video 02:17 in the echo dot 2 speaker and I instantly got sick and stopped watching this video midway. I had vomiting tendencies. Not sure whether the KFC had some issues but I felt the sickness kicking in when the sound got louder and louder.

Thank you for making this video. I do agree 3M is one of the most innovative companies in the world.
