Damping is the mechanism by which oscillating systems lose energy, causing vibration amplitude to decrease over time. Without damping, a struck bell would ring forever; a room would reverberate indefinitely. In reality, energy is dissipated through multiple mechanisms: internal friction within vibrating materials (viscoelastic losses), viscous drag in air, and radiation of energy into connected structures.

In room acoustics, damping directly relates to reverberation time. A room with high damping (lots of absorptive surfaces) has a short RT60 because sound energy is quickly converted to heat. Materials like acoustic foam, fiberglass panels, and heavy curtains provide damping primarily through viscous friction as air molecules oscillate within their porous structure. The treatment calculator helps quantify how much damping is needed to achieve target reverberation times.

In loudspeaker design, damping controls cone behavior. The damping factor of a power amplifier — the ratio of loudspeaker impedance to amplifier output impedance — affects how quickly a speaker cone stops moving after the signal ends. Higher damping factors mean tighter bass response. The Thiele-Small parameter Qms specifically quantifies the mechanical damping of a loudspeaker driver, while Qes captures electrical damping. Together they determine Qts, the total system Q that governs transient response.

SonaVyx measures damping effects through several tools. The RT60 tool directly quantifies room damping via decay time. The impulse response reveals how quickly energy dissipates after excitation. The speaker measurement suite extracts Q factors that characterize loudspeaker damping. When resonances are detected by the problem detector, adding damping is often the prescribed solution.
