The Coltman Paper concludes exactly the opposite and is concerned with acoustic losses which end up being statistically insignificant. There is no difference in flute tone due to the pads.wkzh wrote:I managed to fish out a paper by Coltman... apparently Schmidt pads DO change your tone. It makes you brighter, essentially: reflects higher frequencies better, doesn't do much for lower frequencies. That, actually, seems to be a pretty predictable result, but when it comes down to experimentation... heheh, most of us don't have the patience and expertise.

There is another effect which is well known and favored positively which involves the support of a pad's backing. All types of pads generally benefit from this type of installation procedure or having keycups supporting this design."As a general conclusion, most types of pads now in use have, when properly installed, acoustic losses that will not contribute detectable changes in power or tone quality of the instrument"
In general, Schmidt VS Straubinger...Schmidt is a vast improvement over the Straubinger design in terms of solving the tearing problem with two unique innovations (one of the pad membrane itself and the other in the retainer cup design. (Both use the same ultrasuede as a cushion). These form the basis of Jim's patent.
The upshot of all this is that it really matters little WHAT TYPE of pad you have in there. What is more important is HOW was it installed...Tone will not be affected.
