I just discovered the greatest acoustic treatment!..

...thought i'd let you lot in on my find !

I was recording a bit of french horn yesterday in my mates studio with a nice sounding hall that i use for strings, drums etc, but the landlord also likes to use the room as a gallery / party area etc so you never know what you will find there. They were obviously planning to have a bit of a get together there that night as there were about 50 standard (spandex?) balloons tied to the ceiling. ..... dead as a diplodocus! ... which really narked my actually, cos what i wanted was the hall sound. I had to really shift the room mics to get some ambience!
Anyway, it got me thinking that i could use a few scattered round my mix room.

Anyone know for sure if my theory holds helium?!

Man I hope so. Could do with some brightening up round here!!

Sounds reasonable though. The whole different densities, and diffuse surfaces thing.

I'm just thankful I don't have to fill my 703 traps with helium every week..

Ha! Great find!

I'll try that out the next time I have to do remote recording in a bar I frequent.

Don't helium balloons deflate in a few days?

Yep. There is a gel you can buy that can seal them for weeks or more though...

I have a helium balloon in my house that's been floating for 6 years now and shows no sign of ever coming down

Will mylar have the same effect? Or do I need NOS vintage balloons? heh

I've just begun using overweight people for sound treatment. With the economic downturn and whatnot, it's not too expensive these days.

i'll bet no, for 2 reasons:


1. nitrous oxide has a different density than helium
2. you'll never get around to actually recording because of the wah wah wah WAH WAH WAH WAH WAH WAH WAH WAH

As sound travels through helium three times faster than through air, I am assuming that what happened in this case was some kind of extreme example of refraction-reflection, similar to the effects found within temperature inversion at an open-air rock concert, where the sound travels through the cold air above the audience and bounces off the warm air of the audience and returns to the cold air. The audience complains the sound was not loud enough, but people living five miles away, trying to get some sleep, think it is more than loud enough.

Its because of the balloon shapes. They were acting as diffusers which work great in live areas. Its no the helium.....lol nice try. Look into acoustic behaviors and you will see what I mean. Its the balloons braking up wave forms thats why it sounded dead.

so in that case
those odd balloon's in weird shapes of cartoon characters would work even better.

and if its not the helium, you can just blow them up yourself, bluetack them to the ceiling if its low enough

Yeah, but if you use that gel, you lose a little tightness in the low end. Vintage helium is the only way to go. I have a helium tank from germany used in WWII, if you are really serious about your music, you gotta use that. I could be tempted to sell for $5000.
Also, don't forget about the caps used on the tank, they should be serviced by a professional, but the waiting list is 12 months right now. Anyways, I've had my tank modded, and it really does have a nice top end now, very airy.

This method can also be used for insulation in the winter.

While you are experimenting, grab a few cans of large expanding foam from a Home Depot or some store like that and fill some balloons with that. Just experiment with the first few to see how little foam you have to put in it for the foam to expand the balloon fully and hopefully the chemicals in the foam won't disolve the ballon (do the first few on some cardboard just in case, that stuff is a bitch to clean up). It will be a one time expense as these will never deflate! The foam is light enough to rig/staple to the ceiling with some cheap decreative fish netting. The Card & Party stores will have cheap balloons in packs of all the same color. Once the foam sets you could even just cut the ballon off. If you also grab a couple small pcs. of wood and a vice grip pliers you would not even need to put a knot in the ballon to seal it, just clamp the end and let the foam expand fully. Have some fun with it and as allways post some pics LOL!!!

Back in the '60s, there was a Saturn V moon rocket test here that was done on a day when there was just such an air inversion. Many people in town didn't hear it, but it broke windows in Nashville, 120 miles away. stike

I wouldn't do that. In the sealed balloon the foam will never dry. It will foam up at first but then revert back to its gooey, deflated state it was in the can.

I had a smart idea last time I moved to use this stuff as a makeshift packing material. I wrapped some gear in plastic, placed the gear in a box, put a bag on the end, squirted in spray foam and folded the bag over the foam (which sealed the foam in). When I came back a few hours I had a box of sticky, drippy, mess.

The mylar ones last just about forever (my two daughters have dozens of disney and princess mylar balloons around still from birthdays.)

The more reflective surface of those might be interesting too.

These helium balloons - they are only half measures.

Vee haf here in our studio an original Great War Zeppelin, the same one that was flown from Germany down to Tanzania to give support to the valorous Colonel von Lettow-Vorbec and his askari army. It is not well known that this historic craft was then flown to Hawaii, and was the precurser of the WWII raid on Pearl Harbor.

You can be sure that this beats most installations of mere "clouds".

Nice one. I hope it's to the benefit of you're drum sounds...

erm... It has come to light that the balloons do not contain helium. They're just pinned up to the ceiling. That sort of nullifies a lot of the speculation on this page.

So did you ever carry through with the experiment? Perhaps if you made a vocal booth out of a balloon gondola to raise it off the floor. You know, the original one used in the recording of 99 Luftballons....

This has to be the most punny thread in the history of GS. And for that I am grateful.
