Running Window Averaging
Running RMS level, or Leq, is the root mean square (RMS) value computed over the last N seconds, or the integration time. The single-shot, continuous, and block-by-block linear averaging are three special cases of running RMS level or Leq.
For single-shot linear averaging, the integration time is the acquisition time. For continuous linear averaging, the integration time is infinite. For block-by-block linear averaging, the integration time is the block duration time.
The following figure shows a running window averaging.
Older blocks containing older samples are dropped as you send new blocks of data to the measurement function.

A level measurement provides a quantitative description of the overall vibration acquired from a transducer. You can perform sound level and vibration level measurements with time-domain or even-angle signals.
