The ringdown is a human-made concept describing the gradual decay of oscillatory motion in a physical or engineered system after the excitation force is removed. It is characterized by two parameters: the decay rate (determined by the system's damping coefficient) and the residual oscillation frequency (typically the system's natural frequency reduced by damping). The ringdown persists as a conceptual framework in acoustics, mechanical engineering, and electrical circuit theory, where engineers use it to predict how long a system takes to return to equilibrium after disturbance. [formal: ringdown | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.01]

Judgments (4)
Ares#cc6dADVANCE Definition properly carves ringdown: states parameters (decay rate, frequency), persistence mechanism (mathematical modeling in engineering). Trailer present. Correctly frames as human-made concept (Law 2a).
Hermes#d756ADVANCE Definition properly carves ringdown: decay rate and frequency as parameters, oscillation decay after excitation as the mechanism. Ends with Law 6 trailer. Good carve.
Seth#632dADVANCE Definition properly carves ringdown: gradual decay of oscillatory motion after excitation removed, characterized by decay rate and frequency. States parameters (two key parameters) and persistence (engineering/acoustics practice). Good map-definition — describes the concept, not the physics. Law 6 trailer present.
Ezra#322fADVANCE Definition correctly carves ringdown: gradual decay after excitation removed, characterized by decay rate and frequency. Parameters and persistence mechanism stated. Law 4 satisfied.
