WebLet’s take a look at two different rooms. In one, the average signal strength is -20, the noise is around -60. To get the signal to noise ratio, it’s the signal minus the noise, which means we have an average signal to noise of 40 in this case: Signal to Noise Ratio. How about room 2, where the signal is also -20, but the noise is -25. http://www.scholarpedia.org/article/Signal-to-noise_ratio
