Man, the sound science content on this channel is always so fascinating and super interesting, amazing as always Benn
-
Stumbled across this channel, now I'm glad I get to watch all your other videos!

In some dreams (or actually more dream-like experiences like sleep paralysis and DMT trips) I've heard some incredibly loud sounds, it felt like somebody was tearing the world apart. Somewhat terrifying when it happened, but also wonderful to be able to experience such extreme sounds without destroying your ears :D
-
The “loud distorted voice with noise” vs “soft voice with no bg noise” bit was really cool. Great video!
-
One thing that really struck me about this video is what an amazing job you did recording your voice so that it sounds consistent in different environments. The first few scenes were quite jarring as I was trying to figure out if you'd recorded your voice indoors and were miming outdoors, but then decided that was silly. Super interesting video - thanks for making it.

My favorite sound factoid has to do with rocket launches. The pads at Cape Canaveral have these MASSIVE water pump systems on them that flood the launch pad with thousands of tons of water as a rocket takes off. Not because the heat from the exhaust of the rocket might melt the concrete, but because the "sound" is so loud that it would actually liquefy the concrete just from sheer pressure waves if there wasn't that much water present.

Just found this…. And subscribed. Probably less interested in “synth stuff” but the deep dive into science was so done much better than most media outlets…. You handle technical issues without dumbing them down OR getting boring… pretty rare… keep it up!
-
You have some of the best science videos out there. Really excellent content. Thank you for taking the time to explain these things.

I’ve never seen this channel before. YT just decided to recommend it to me today. I was quite impressed with the combination of quality, scientific skepticism, and clear explanations… right up until about 11:15. Then there was a duck and all of a sudden, I’d somehow hit the subscribe button without realising that I was doing it. I’m not even mad.

"Whever try to I break free from the pro audio or synth stuff[...]" it is always freaking amazing! Please keep doing these great videos! But also make sure not to die out on sea.

I got into audio as many of us do, through music. But stuff like this is what keeps me interested. It’s so endlessly fascinating, and I could (and do) get stuck in the scientific minutia for hours. Great video, Benn!
-
wow man, this channel is amazing. How is it only now ending up in my feed?! Thank you for your time and sharing your experience.

Just casually holding a duck 😅 Amazing video, Benn! Thank you for an entertaining and well informed video!
-
I studied audio engineering for 2 years in college, but we never went into the physics deeper than enough to know how a microphone works. This was really fascinating!
-
Thank you for taking the time to do this video, Benn!

Love this video. Always love watching informative videos that broaden perspective on subjects taken for granted like sound.
-
The duck at the end made my day ❤ I absolutely love these type of videos, ever since you made the video on sonic weapons, I've been hooked on these topics and your brand of presentation. Hope there'll be more in the future!
-
So, on Earth, with typical means of sound propagation, there's definitely a limit to how loud things can be, but, I mean, if you try hard enough you can always cram more air molecules into a finite amount of space... until it becomes a black hole.

Hey Ben this was super cool and I love that you have almost hyper-fixated on such an overlooked aspect of life and the world around us. I wish I understood the physics associated with some of these principles in greater detail.

I just found this video. And I have to say, I absolutely LOVE how creative you are with your videos. Earned my sub instantly!
