Evolution of sound in a medium whose properties irreversibly vary in the course of wave propagation, is studied. For example, a gas that is a particular case of a Newtonian fluid is considered. Hysteresis curves, pictorial representations of irreversible attenuation of the sound energy, in the plane of thermodynamic states are plotted. The irreversible losses in internal energy are proportional to the total attenuation and depend on the intensity and shape of sound waveform. Curves and loops for some periodic (including the sawtooth wave) and aperiodic impulse sounds are discussed and compared.
