The helmholtz resonator (named after a Mr Helmholtz who discovered it) can best be demonstrated by taking a normal soft drink bottle and blowing over the mouth of the bottle - a note is produced. Now place some cotton wool in the bottle and try again. You will notice the note has reduced- well not really, the note is produced but the wool absorbs the resonance and turn the sound energy into heat! Imagine, if you lined a whole wall with bottles of various sizes, all filled with insulation material. You would now have a low-mid (200 - 500Hz depending on the bottle size) absorbing wall that as well as absorbing the low mids would also reflect or diffuse the high frequencies. I haven't tried it yet but it would be worth trying if you are short of cash because bottles are cheap.
has anyone ever actually tried this? i was thinking of attaching some pieces of particle board using hinges, lining it with bottles like this... and then recording inside of that. i think that maybe sounds kinda ridiculous, but would this sound cool? has anyone tried anything dealing with using plastic and glass bottles like this?

do you even think it would be worth the effort?

It would certainly be a great conversation piece...
