Description

Properties
Dissipance, or dissipation factor for sound power, is the ratio of dissipated sound power to incident sound power. The dissipation factor (DF) is a measure of loss-rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of quality factor, which represents the quality of oscillation.
$$\delta = \frac{P_d}{P_i}$$, where $$P_d$$ is the dissipated sound power, and $$P_i$$ is the incident sound power.
$$\delta$$
