SUMMARY
The discussion focuses on the effects of transitioning sound propagation in air from an adiabatic process to an isothermal process, particularly regarding particle velocity. It is established that while the wave velocity decreases due to a reduction in the bulk modulus of air, the particle velocity remains largely independent of this transition, as it is primarily influenced by temperature. In an isothermal process, particle speeds remain constant, whereas in an adiabatic process, particle speeds oscillate due to pressure-induced temperature changes, contingent upon maintaining thermal equilibrium at lower frequencies.
