Visualize Noise Power
This model plots the noise power estimated by the Voice Activity Detector.
To explore this model, tune the Frequency (Hz) parameter of the Sine Wave block and observe the noise power estimate updated on the Array Plot block.
Zoom in on the Array Plot to verify that the Voice Activity Detector outputs a good estimate of the noise tone.
