Julien,
A scientist would estimate. Examine one quarter of the rose and count
the openings. Give a best guess for the average size of the hole in
that quarter, in square mm.
Opening = average size x number of holes in quarter x 4.
What would be really interesting would be to know is what happens as
the openings get smaller and smaller.
All the best,
Art Robb
Hi all,
I was just wondering if anybody knows how to measure the opening
surface of a lute rosette ?
I should explain further : I'm trying to compare some lute roses
patterns,because I believe one important thing for sound , to some
extent, is the opening of the soundhole (on a guitar, for example, it
is quite easy to measure the opening surface , and to increase or
decrease it, and eventuelly to find the best soundhole diameter).
The problem is, that for the same diameter, two different rose
patterns
will probably show a different opening surface ! It would be then
interesting to know precisely how much, when choosing between
patterns with a customer for example.
Is there an easy and simple method to measure or calculate this
surface? (I'm not talking about some hard computer program or complex
mathematical formula ...we're lute makers after all ...)
thank you
julien
