Acoustic resonators in place of room treatment

Has anyone tried egg cups?

Is there any reason why acoustic resonators have the market cornered on all metal cups/bells that resonate audibly and improve room acoustics?

After all, to extend the analogy, Rives only does professionally with more know how and expertise than what DIY'ers can also achieve with fibreglass chunks etc....i.e Rives follows well known acoustic principles and science...

Has anyone tried egg cups?

I did years ago -- egg-cup boxes the paper variety. On the ceiling and side walls. The results were OK, I guess -- but the looks are out of this world.
Forget it. (in the old times, makeshift studios used egg cups)

Shadorne, Is this what you meant by "egg cups?" Initially, I thought this but decided you meant the cups you put soft boiled eggs in. Only they would have a very high resonant frequency such as the SR Arts and Acoustic Resonators. Of course, everything would depend on what that resonant frequency would be as well as what resonant frequency would contribute the most. Everything would be trial and error.

Correct - I was thinking of a metal egg cup for enjoying your boiled egg.

I agree about trial and error - which is the exactly the same issue for DIY acoustic treatments ....you build some panels and then try them out and find a good position for them.

It occured to me that metal or ceramic egg cups, bowls, bells, thimbles, wine glasses, abalone shells, chimes and other similar items must necessarily behave like Acoustic Resonators so why haven't people tried them? (Note: There is extensive experimentation with DIY acoustic panel stuff from heavy curtains to shaggy rugs - so why not the same DIY solution with "acoustic resonators" ?

Please don't tell me there is a quantum dot or something super special ONLY about Frank's version - surely there are other resonating things out there that might work too?

Anyone try five crystal wine glasses strategically placed on tables around the room?

The crystal glasses would probably have to be on the walls. Height is very important. Why? I haven't a clue.
