Acoustic Geometry shows how sound works in rooms using Nerf Disc guns, 1130 feet of fluorescent green string, and Moiré patterns, and a before-and-after example.
Because they want to keep you on the RU-vid platform for as long as possible by making you go down the RU-vid rabbit hole! You come on here for a quick 5-minute video about How Sound Works and 2 hours later you're on here watching videos of fighter jets breaking the sound barrier.

I've watched hours worth of "tutorials" on acoustics and sound proofing rooms, but nothing, NOTHING came even close to these 3:33 mins. I feel enlightened! Thank you!

Well explained with clarity. I love the nerf gun example. It took me a while to understand after complicating me with golf ball theories when I studied room acoustics. Wish our teacher explained like this.
Omg why was the switching back and forth from the treated room to the untreated room so incomprehensibly satisfying?! I could honestly watch that all day long lol

As an artist with a home studio - This is an excellent example of room acoustics - I see why it’s so important and I appreciated the demonstration with the wooden clappers at the end - made all the difference in my understanding! ☺️
Extremely informative. I've learned as a musician how important room acoustics are for recording but it's insane to think about how much this science is actually applied by life on earth without the vast majority of life even considering why or how it's possible. Normally lifeforms process these noises without even thinking twice about them, but they even help us navigate the world around us. Blind humans that have learned the art of echolocation are a perfect example of this. I would never want to lose my eyesight or sense of touch, but losing my hearing would be even more devastating to me.
love the simple essence of your knowledge... gets the messege across with humbleness... respetcting the intelligence of the audience.. some of these videos take you step by step like we dummies... thumbs up...
This by far is one of the best videos about echoed sound ive seen thus far. . . Straight to the point with a long drawn out explanation. He even had examples.. i love it !
That is not echos sound, but reflection of sound refers to the bouncing of sound waves off a surface. This can occur when sound waves encounter a solid object, such as a wall or floor. Echo is the repetition of sound that occurs after the original sound is produced. It happens when sound waves reflect off a surface and return to the listener.
Wow the wood clapper examples are fantastic! We (I work for an architectural company) talk to clients about this sort of thing, but to actually show them a comparison like this will be brilliant! Great video 👍
I'd say it most definitely depends on the size of the recording area. I know people in bands that have told me to place carpet on the walls of my studio, but in my case that just wouldn't work. It's such a small room, that if I were to do that it would kill the sound almost completely, when all I really want to do is control it.
@@KKTRLZ You are talking about a sound studio instead of a room to live in. Would it not be easier to make all walls absorb sound and then use microphones on different distances and after effects to get the perfect sound.
@@computerjantje Well, there's only so much you can do post production if the recording itself is already either too flat, thin, boxy, distorted, etc. It's almost similar to video. You can't enhance resolution that isn't there. I'm speaking generally of the vocal recording area and not the setting of levels. I think it goes without saying that no amount of EQ'ing is going to fix a badly recorded vocal.
I just would like to say that the previous comment is still valid 9 years later! LOL! After seeing so many videos and reading several explanations and this one was all that I needed! Thank you so much!
I didn't search for this, but I'm glad I watched it. Not just for the fact he used Nerf guns to explain sound, but while I knew about absorbing sound, I didn't know about diffusion. I learned something today, thanks man.
This is a great explanation and demonstration of how acoustics work in a room. The argument is explained in plain language and makes for an easy understanding of the topic. However, man I tripped out mad in tha last bit. Well done, cheers.
A wonderful video - Thank you for that. One ironic thing came to mind with your final statement: "Your room will sound a lot more natural, but will look a lot stranger."
Great video. It’s really nice to see someone do an A-B comparison that’s actually useful without having to fumble with youtube’s playback controls to try to repeat the different clips....
As a poor man's solution, I hung corduroy fabric on parts of the walls using small diameter wood poles, hooks and brackets - like wall tapestry hangings. It improved the sound immensely. Thanks for the great video.
Fascinating and informative! We are currently in the middle of recording at our home studio and trying to get our sounds right and this puts a wonderful visual on WHY things happen the way they do.
The best way to understand how sound moves is to tap a bucket of water. You get a splash where you tapped the bucket, then later at the other side and back. Thus, if you put your speakers 18" from the wall your head should be 18" from the rear wall for optimum bass - try it!
Prince Westerburg Hey! Mind further explaining that thing about having my head 18" from the rear wall? I didn't undertand what you meant by having the speakers 18" away from the wall. I mean, what wall? The one in front of the speakers or at the back of the speakers? Is the rear wall the one behind me/in front of the speakers?
Acoustic Geometry Did you see my question on your other vid? I live in a loft and cannot play my system loud at all. I have a pair of Martin Logan Electro Stat speakers. I was wondering if panels make a significant different if you are playing at lower volumes as well?
The Only Draw back of moving faster than the speed of light is that you only get to see the darkness. this guy was way ahead of the time and way ahead of youtube tutorial boom. loved the tutorial.
Wow ! All that material ! Many people use solid rock maple butcher block counter slabs, see them here : chefdepot.net/butcherblock7.htm (Made in USA and Free Shipping)
I watched this video almost 8 years after it was published and in that time I couldn't find a similar one that explained the problem as well as John Calder did. Great and helpful video, thanks and more of them please!
This is what I figured after playing instruments for so long. Simply having a fan set to low messes with sound frequencies too. It's interesting how it causes them to sound. Thanks for the video!
This is very simplistic take on the issue and doesn't really tell you how complicated it really is to make acoustic treatment. It takes time, knowledge and experimentation (and accurate measurement, not your subjective opinion) to do good acoustics. And it's way too easy to spend a huge amount of money on treatment that isn't effective or is wrong for the said room.
It's also very easy with a little money and ingenuity to make a big difference in a bad room. This video is good for a 3 minute intro to acoustics. Just putting up a few strategically placed absorbers can make a big improvement, but it takes a lot of expertise to make a 'reference' quality space. It depends on what your goal is.
The best before and after editing ive seen on youtube, wish everyone did this. Instant and direct comparisson with resulst u can compare without waiting several seconds for other clip to play !

This is explained very well. Unlike most people, I can tell you put a lot of thought, planning and effort into constructing this video and presenting it. Thank you for posting this.
I like how in a video about sound, one can still learn with no sound at all. I watched this on mute and still came out of it with valuable information. Thanks!
