No I'm pretty sure it was Qtex factory because the balloon they inflated was a big heart shaped balloon and the TV show was called "How Its Made"

Thread resurrect, stumbled upon this, yknow, googling about balloons n stuff.... normal behaviour....

https://www.researchgate.net/publica..._When_They_Pop

I'm interested in their conclusion that balloons aren't an impulse noise. Thoughts?

It seems like they only measured pin pops. Maybe pops due to overinflation work differently? There loudness is also much less than overinflation. Overinflation can cause pops that are upto 165db and in this research paper they reached noise levels of less than a typical lawn mower.

I currently use a Rode K2 for my videos. It is rated for sounds upto 162db. Before I used a Rode VideoMic Pro+ which is rated for upto 133db. Ever since switching I hear a lot less clipping when balloons pop. But it can still happen.

My guess is that if a balloon is pin-popped just before the time it would have popped from overinflation (i. e. after the last possible breath it can take), the noise will be fairly close to the 165dB. Usually balloons are pin-popped before that maximum point. When going past 98%-99% capacity overinflation, the noise may increase drastically when it is popped via B2P.


This is just a guess...

There's been a lot of thefts of helium-filled balloons recently. More so than in the past, so they're going up. I think inflation is to blame.

That's a fascinating paper, neat to see that they found an entirely different mechanism from the two standard hypotheses. Love to see that we're not the only ones interested in this stuff

I've been trying to see if I could come up with any interesting metrology experiments involving balloons, like optical techniques for precisely measuring the skin thickness of a balloon, but I haven't settled on anything concrete yet. Optics is only tangential to my field of study so I'm not the most fluent in its application.

That is quite possible, but good luck hitting the right moment. Plus not every balloon would reach 165db anyway. You can b2p 10 balloons from one lot and each one will sound a bit different. If you take balloons from different lots, brands, colours and brands the differences become even bigger.

I am sure manufacturers run tests. Balloons are made to pop, and they don't want to make unsafe products. I have seen another study showing levels from different sized balloons, and they all burst around the same level. Must be a fun job - being told to make something as difficult to pop as possible without going over 170db, then overinflating and measuring prototypes, and randomly overinflating a few balloons from every batch for quality control.
I don't think even 1 b2p is save per day. If you experience pain, discomfort, unusual sounds (like tinitus) it is save to say you caused permanent ear damage. Is it enough to matter in the long run? Who knows. But better to be save than sorry.

It is the same with the time you are allowed to stay in the sun per day with x skin colour and y UV intensity. I would guess even 1 second in the sun would leave some permanent damage, even if it is not visible or measureable without an electron microscope.

There are lots of things in life where zero is the actual safety limit. But governments and scientists usually allow some tolerance levels because otherwise society would collapse.

Aging is not magic, it is just the sum of permanent damage that the body experiences during its lifetime.

True. If one were to B2P a weather balloon (don't try this by mouth, lol), it would be more of a "FOOF!" when it pops, more that than a very "sharp" snap sound.

i know that exact show that you are talking about at the very end of the episode she puts a huge heart on the valve and blows it up huge and then holds it in front of a florescent light and looks for defects.

think this is the one that you are talking about.
