International Workshop (1st) on Thermoacoustics Held in Hertogenbosch The Netherlands on April 22-25, 2001

Abstract

The first theory of sound propagation which has fully accounted for the effects of heat conduction on the speed of sound was given by Kirchhoff in 1868. Starting with the energy equation for an ideal gas which was proposed in 1842 by the German physician Robert Mayers, Kirchhoff was first to formulate a version of this equation in which density fluctuations were the only non-thermal effects induced and thus the sole "cause" of a correction to the Newtonian value of the sound speed which was initiated by Laplace in 1821. The linearization of this equation permitted its combination with the small-disturbance approximations of the equations of motion, and a theory of sound propagation was established.
