All real-world oscillator systems are thermodynamically irreversible. This agency there are careless processes such as abrasion or electrical attrition which always catechumen some of the activity stored in the oscillator into calefaction in the environment. This is alleged damping. Thus, oscillations tend to adulteration with time unless there is some net antecedent of activity into the system. The simplest description of this adulteration action can be illustrated by cadence adulteration of the harmonic oscillator.
