Steel String Chladni Patterns

Post by Dave M » Sat Jan 12, 2019 3:40 am

Most of my generating of Chladnis has been on classical guitars.

I was testing a recently completed steel string and was having a bit of difficulty exciting the top. It struck me that perhaps the much stiffer top structure of the SS might need a lot more acoustic energy to get it going. Would people say that is the case?

I am using a 4 inch speaker in a closed enclosure with a domestic stereo amplifier being fed from VA. I do still have some headroom but I was at levels that have worked fine with classicals.

I can't say I've noticed much difference, though there probably is one. Twice the power would only be another 3dB. I'll have the gear out next w/e, so I'll see if I find any difference.

Well I can answer my own question having finally got round to doing a bridge rotation test. I have a very stiff top!

It is falcate braced and I thought it a pretty good, loud guitar with plenty of sustain, but maybe I haven't put it alongside a really responsive guitar.
