- Are you getting the best sound from your concert hall? Fear not, for here is Tomorrow's World presenter James Burke - one of the all-time great explainers of things - demonstrating how to get the best acoustics possible from any building, using nothing but the scientific principles of acoustic scaling, an anechoic chamber, a miniature Maida Vale studio, a guitar, some sweet fretwork... and a gun.
This clip is from Tomorrow's World, originally broadcast 30 October, 1970.

Never thought I would see James Burke playing flamenco guitar and waving a gun around in the park.
Ahhhh that voice! The voice of my childhood. What a bloke.
And what a guitarist he was.
Is it me or were presenters like JB and his ilk just so much more interesting and polished back then. Absolutely perfect delivery, such a talented guy.
They're looking for a different type of polish these days. More snake oil or used car salesmen types.
Such an underrated presenter.
He is an absolute legend
Best science presenter the BBC ever had.
Not sure James was ever considered underrated. He was a recognised brilliant presenter. And, it turns out, a pretty fair Spanish guitarist too.
I had no idea James Burke was a brilliant guitarist in addition to all his other skills! Bravo!
Is there no end to this man's talents?
I could listen to him explain anything. Coming up with Connections was such a brilliant idea.
I was waiting for the seagull to fall out of the air after he shot that revolver
James Burke can play the guitar and play it well. I learned this today.
Burke also did 'Connections', a series as powerful as Sagan's Cosmos. Many books. An unsung hero of purposeful mind.
Every school should play these Burke anything.
His overall style is ahead of their time. Mind blowing
That man can do everything!
He played that guitar very nicely. His brother Alan is a lovely guitar player and singer too!
Omg
This man. This treasure.
I've had a crush on James Burke for literally 60% of my life. (We in the U.S. didn't get to see him until PBS picked up Connections in '79.) Every once in a while I search TH-cam to see what I might find with him in it and now I've found this. I'll be sharing the link with a friend who's a been a sound engineer for many years.
I admire James Burke, and saw him give a lecture once in Arizona. I had no dea he had such musical ability. If born later, he may have been a pop star.
It's like a Tom Scott video, but from 1970. I do miss the times that TV gave us nerdy, but precise narrative. Tomorrow's World was my favorite programme, even as a young kid. I also love how this video was less about acoustics and more about James proving he is an expert player of the Spanish guitar.. 🤣🤣
When I was a little kid, I grew up watching connections and connections to on TLC before it completely went to pot.
I fell in love with James Burke and his tan leisure suit. He made everything so entertaining and so accessible while not talking down to the audience. But I never knew he was a guitar player.
What a find..
Pure Gold.
One of the best recommendations ever..
they dont make television like this anymore
Well I discovered this guy in an obscure section of the Internet, the dry port blank timeless explanations are maddeningly exciting.
To discover this little clip delving deep in audio wow. I still think they faked the guitar but I don't think they would!
Perfect delivery.
No one is like Burke.
Love the video, love Burke, but that 1:8-scale model would only be accurate if the air inside were 8 times as dense, surely?
Although it seems like it should be intuitively, that not actually the case. Speed of sound = frequency/wavelength. The density of the air has a negligible effect on the speed of sound, which is only affected by temp and humidity. As long as temp and humidity are the same in both, then the only parameter that needs to change to scale the acoustics properly is frequency. The full scale (Ffs) frequency and scale model frequency (Fsm) are directly proportional to the scale ratio (in this case, full scale/model scale = 8/1 = 8) by the formula Fs = 8 * Ffs, ie the original frequency*8.
The reversed fader in the control room mixer is amazing!
I was wondering if they were actually reversed or if they cut the audio to fit. I wouldn't be surprised if they were reversed that was an early consul and I could see a design like that.
The BBC were notorious for having their faders (both audio and video) upside down to everyone else's. Have no idea why.
I did wonder if the snatches of music were dubbed on, though.
@@ambroseshepherd6861Apparently the idea was that if the presenter was about to experience a heart attack or some similar disaster, they could collapse forwards and close the fader before passing out.
Never knew that, thanks!
An excellent share! A fan and an admirer from Pakistan.
Young people don't realise that ALL BBC presenters in the 1960s and 1970s were expected to be competent musicians. Michael Rodd was also a guitarist, and Patrick Moore played the xylophone. Michael Barratt was given an exemption by passing membership of the Magic Circle.
I assumed that you were bullshitting, but damned if I didn't just watch a video of Patrick Moore playing the xylophone!
Ken Dodd played the fiddle.....
Benny hill played the casternets....
Frank Spencer played the fool. Sorry!
Quality
Dream Video
It took years to sort out the acoustic mess that used to be The Royal Albert Hall. Next time you watch a Proms concert on television, look at the ceiling, if it's in view. The structures on it, fixed a nightmare echo, which can be heard on earlier recordings done there, such as Cream's Farewell Concert prior to their later reunion; the difference is obvious.
And it’s still bloody awful despite what they’ve spent on it (for rock music, anyway)
I didn't know the range James's talent
Strictly speaking, the materials and finishes of the walls and furnishings on that scale model need to be modified also. There are mathematical ways (dynamic similitude, Buckingham Pi theorem) of calculating what adjustments need to be made to determine equivalent absorbencies.
WONDERFUL
Amazing!!
This guy is from the future!!!!
The discover of project LS3/5
Clever burke.....
Olé!
yeah for rare James Burke.
James Burke plays flamenco guitar? And well! Who knew?! With respect to acoustic design… I suppose nowadays all of this would be simulated on a computer using sophisticated sound modeling software.
Ah, how the world has changed.
Synthesized dead noise for testing.
Computerized acoustic modeling, up to and including changing the sound environment by adding people, objects, etc. Regression testing to reduce the time of experiments from hours to seconds.
AI listeners to rapidly determine what environment is likely to appealing to the largest selection of human listeners.
AI noise (ok, music) generators.
How long will it be 'til we have AI music generators playing to AI listeners without humans involved?
And none will be the voice of Mr. Burke.
Hmm, if our modern earbuds get any deeper, they'll be implanted in our brainstems, and all that's left of the acoustic environment will be glial cells gossiping about who has been naught and nice.
