Construction and use of mechanical lips to determine the acoustical properties of trumpets.

Should one purchase an expensive professional trumpet or will an inexpensive student horn have the same sound quality? To answer this question, we have built a system to determine the acoustical characteristics of trumpets, including a mechanical device to replace the lips as a sound generating source which is designed so that the input into the instrument is the same every time. Data has shown that the harmonic structure of two trumpets of the same make and model but differing in age and condition are identical.
