calculating standing waves to find fundamental frequency


Platinum Member
I've heard of standing waves in reference to acoustically treating rooms.

It's when a wave bounces off a wall and reinforces the same frequency wave on its way back.
EDIT: these standing waves are undesirable, and can be eliminated through non-parallel walls,
rounding of corners and edges, sound absorbing panels, and other means. /Edit.
I suppose it could also be applied to the interior surfaces of drums.

That's different than a fundamental frequency though.

I like Gruntersdad's winter/spring solstice tuning method better though.

You don't tune a drum. You tension it.
Ronn....are you saying this cause you are

(a)joking around
(b)employing hyper vigilance in using appropriate nomenclature
(c)because you are implying that the drum already has a fundamental tone or "tuning" based on its physical size/quarter wavelength relationship....and you tension the heads to support that

Of course, I can't speak for Ronn, but I feel the same when I "tune" a drum. I'm tensioning the heads such that the instrument delivers according to it's design/construction. I select a drum based on what I want it to give, pretty much in the same way I would select a cymbal.
