Bat fact:only mammal that can fly Because of the energy required to sustain flight, bat body temp much higher than other mammals, therefore any disease that moves from them to us is trouble, as our normal defense mechanism of increasing our body temp doesn't work.. bat only mammals that don't get cancer as their requirements for cell repair are much greater due to heat damage incurred during flight
Man, I admire your enthusiasm for all things sound/music/science. I thought *I* had a lot of time and energy for those sorts of things, but you’re an inspiration.
Batty Brilliance Benn, loved it, I think your new look channel is about to get really interesting. Exploring 52 million years of bat sound survival techniques makes 25 years of VST and DAW refinement look pretty amoeberish (is that a word..is now: amoeba + ish). Your vid just expands the mind like a magic mushroom, to imagine that all these spectrums have always existed and that organic matter has evolved to tame these realms in order to survive makes working on an cheesy EDM pumper a pointless and selfish endeavor. Where does sound evolve too from here? Legendary stuff old chum, keep up the fantastic insights. Cheers
Dude, I've been a sub for a while, and I periodically use some free time to work my way back through your older vids that I either missed or you made before I was aware of you. I have no idea why you don't have 10 times the subs. Your vid quality is ridiculously high, your notions are better organized than they have to be... I mean, you clearly do good work because you can't stand putting out bad work. I will continue to evangelize. I have learned so much from your segments.
Thoroughly loved this one! Thanks! Now I know a little more of the answer to the question discussed at so many breakfast tables around the world: "What is it like to be a bat?". ;)

Mind blowing. You are a scientist with a great creative mind :)
Wow, i literally know nothing about bats other than seeing them flying around at night throughout my town. Just happened to stumble on this video and I’ve never been more intrigued by an animal. That was the most informative video, i truly feel like I’ve learned a whole new topic
Such diverse content.. from legal stuff and industry experience to biology--but all within the realm of Sound. All fascinating and cool. Keep it coming man!
8:05 I've heard these sounds every night this summer. I thought they were birds! And I asked myself (after my husband who is native to this rural area), "What kind of birds do you guys know of that do this at night? Sounds like some kind of songbirds! Crazy!", My son thought this odd low to high pitch scream was some kind of bird. I now believe it's a bat. Or a Coyote of some kind. Not sure yet. But seems logical in these northern parts of the Appalachians of SE Ohio Valley. But my husband who has lived here all his life says he's never heard a sound like that. If it's not a bat then what is it?
Daaamn son pro audio world needs dark mode bad, burning my retina's here Mindblowing and amazing material though! Thanks for bringing me these video's!
The whole world: SCREW BATS THEY CAUSE DISEASES! Benn: I LOVE BATS!! Firmly on your team though. They are very interesting. Even though they are full of diseases (their immune system is INSANE! look it up :D).
hi benn! or anyone reading! what's the name of the piece that plays in the background at 6:20?? i know i've heard it before & it's driving me nuts! loved the vid, too!
I see a lot of bats around dusk flying all flittery and jittery like they do. Weirdly one bat was flying straight and struggling a bit. It looked like it had caught a small bird? I googled it and yes bats eats birds if they get the chance. I am guessing it was flying straight home to eat it?
This may go south but I’m not familiar with your music career and I’ve been touch and go with your RU-vid videos because I regretfully regarded You as just another pretentious talking head. Boy, I was wrong. You are a pretty fucking cool dood and usually have some great nuggets of information you choose to share with people. I appreciate what you are putting down for us here. Hopefully I didn’t come off as a big a$$hole, I am but I’m working on it.
apologies if this is a silly kind of a question but... If bats can make up to 140db how come we don't end up deaf while watching (hearing) them? Is it due to the frequency range?
They could have low resolution vision through that sonar, or is that too far fetched? I wonder, because it does not seem like anything you'll be able to study, since sonar is also processed in the visual part of the brain
you exaggerate a bit LOL its more like you say "BEH" in "G6" and hear in "B6" when you play a jam you don't think "he is playing at 1568hz I can play 1979.5hz" ^^ then we too have super powers !! :)
Another cool feature of bat ears is the middle ear muscle can contract and separate the three bones of the middle ear to prevent the bat being deafened by it's own squeek
12:08 funn fact: if a fly is resting in one spot long enough for you to (in our perception of time) slowly move your hand above it, without its shadow above the fly, it will not see it coming because it does not recognize the movement anymore. so you can (and I actually managed to do this a few times) pet it.
Let's be honest Benn, either you are from the future or from a parallel universe... started to listen to your music more and more, you're definitely not from now and here. Thank you for enriching our lives with your creativity!
fun fact, if you take that bit where he had the frequency-divided bat calls (somewhere around 7:50 I think) and do the same process again, it's almost exactly the same tones and timbres of whale calls.
Hey man, first thank you for making this channel from the bottom of my nerdy heart. One question: around 14:00 when you are calculating the distance, because your recorder and the bat's ears are in different locations... How can you know the distance the bat is from something without knowing some directional and distance info for you relative to the bat? I suck at math, but my intuition is tingling. Thanks!
Who would have thought bats + Debussy would be so damn beautiful? Your videos always get me to think or feel & this is no exception. These days it feels like I'm always trying to escape manipulative media--so yeah it's really welcome
Damn you Ben! I've been working on a video bringing bats to the synth world, using a crappy heterodyning bat detector, PD, and an Organelle, but now I'll be riding on the coattails of the great Flashbulb! Haha, oh well. I love bats and loved this video man. Keep on making rad stuff.
So I was just taking my dog out, still early in the morning, still a bit dark. and heard a bunch of birdies chirping. Kinda sounded like hummingbird chirps but there was just so many. I looked up and whoa. Bats. I am in the big middle of the city and surprised to see and hear so many. Wasn’t 100% sure till I found this video. So glad I found your channel! This is the first video I have found of yours but looking forward to diving in to your channel! You reminded me that there is no need to have a fear of them. Wow! I was reminded what incredibly amazing creatures these are! Thanks for putting this together!
Well, would you look at Bat errrr That.. a strangely perfect time to post this video Benn. Two nights ago at sunset, when I suppose an insect buffet was just emerging from its cool shadowy roost, two bats appeared and flew right over my head for about 10 minutes, right at my front door. It was fascinating. They were about the size of my hand and echo-locating like crazy. I could hear them chirping clear as day. By the sound of it, they left with full bellies! It's been 10 years since my last close encounter with bats (which happened up on a mountain). Anyway, would love to hear the fruits of more supersonic nature adventures. The weirder the better! Thanks for posting Benn and recommending Wildlife Acoustics too.
I couldn't have wished for a better video about this topic. This was very informative and well researched considering this is not your field of expertise. I've always been wondering about how affordable and accessible ultrasound recording might be and this USB microphone looks like an intrigueing thing to toy around with. I'd love to get one of those and experiment. Can you do some follow up videos with this mic? Because I think having an ultrasonic mic is giving you the opportunity to explore other sources of high frequency sounds. Like certain machinery, cars, old gearsboxes lacking grease, electronic components (coils), etc... It's like an accoustic window into a world that's usually hidden from us humans.
Back in college (about 20 yrs ago) I designed a circuit to measure wind speed using piezo electric transducers and a oscilloscope ( just like synths analogue is just better)..your analysis of the bat call and response kind of reminds me of this time.. I also know what Freq domain transformations are and I'd say most of your subscribers are familiar with spectrograms that you used to display this..great content
Adobe Audition tip: Instead of doing pitch shift and then converting sample rate, you can achieve the same thing without any DSP. With the original, high sample rate file: Go to Edit > Interpret Sample Rate. That will just change the sample rate value in the file's header and tell programs to play the samples at that speed. Same outcome with no processing required. :) Other editors can probably do this too. It could even be done by directly editing the files metadata (Assuming it's a standard WAV file in the RIFF format)
It's just awesome to hear somebody that actually knows what they're talkin about. Like factual information that is well in opposed to all of these opinions on RU-vid.
One of my absolute favorites of videos you’ve done. I’ve always loved bats and my body is littered with bat tattoos. Thanks for the entertainment, bud!
Switching to your channel often feels like reaching into a lucky bag that surprises with the weirdest and most diverse stuff. I also appreciate the thoroughly researched information that comes with your videos. Thank you.
Excellent. What industrious work, to answer a question about the amazing, fascinating, echolocating bat--; that I have always wanted to know all my life--; an accurate re-pitching of their echolocative sound-signals, to a range within-which we could have heard them. The evolutionary convergence with the non-echolocative calls of the only slightly larger, typical songbirds--; seems to confirm or corroborate, what might seem to be a particularly logical expectation about how the bats' calls actually would sound--. Thank You--.
To slow it down to 48KHz, you could use Interpret Sample Rate instead of slowing it down and then converting sample rate. Doesn't have to process anything and it happens instantly.
As soon as I saw that increasing interval, I knew it was for honing in on a target. I guess this is why 'simultaneous invention' is so common, because I'd never seen the information, but just seeing it gave me ideas. Really cool. Also I notice a single chirp changes pitch, which I'm guessing helps measure doppler CHANGES during the echo, not just an overall pitch change like you pointed out for relative speed, but to also measure *acceleration*. Kind of how networked games interpolate using speed AND acceleration, until the next network packet comes in. Much more accurate to fill in the gaps, than just sending current speed by itself (I'm a games programmer :) ). In fact it works well to change the tick rate based on proximity, which is what I did with vehicle simulators. Close cars got more ticks. Although I wonder why the frequency went DOWN and the range restricts? I'd have thought it would go up to get more accuracy. Maybe it's tuning the freq in to a specific distance?
