Decay time

Decay time refers to the period it takes for a signal, sound, or energy to diminish to a certain level after it has been generated. For example, in audio or acoustics, it is the duration it takes for a sound to fade away after the source stops producing it. In other fields like physics or electronics, decay time describes how quickly a system returns to a resting state or how fast a stored energy dissipates. It is an important measure for understanding how long an effect or signal persists in a system.
