Some years ago I compared the thermal expansion coefficient of brass and the thermal coefficient for the speed of sound at room temperature. (I think I published the results on this list.) The effect of temperature change from these two effects are in opposite directions, but the effect from the speed of sound is around 20 times as large as the length change of the instrument. _______________________________________________ post: [email protected] unsubscribe or set options at https://pegasus.memphis.edu/cgi-bin/mailman/options/horn/archive%40jab.org
