Signal to Noise

In physics, the SNR – signal to noise ratio is the basically the power of signal (the information we want) divided by the power of noise (the information we don’t want).

In our business and personal lives, maybe the same principle applies. And therein lies a challenge.

The signal we look for – things that are meaningful to us – the art, relationships, meaning and the contribution we can make, amongst many others, is pretty much a constant. when we have clarity of purpose, when we are loved, we don’t go round saying I need more of it. These things are not consumables.

On the other hand, the noise in amongst which we look for signal has increased exponentially. The ability to communicate , social media, advertising, a drive to consume, and spam in all it’s forms has changed our signal to noise rations out of all proportion in the last twenty years. When we don’t understand that, we can lose signal altogether in trying to deal with the noise.

But there’s an upside. Without noise, we wouldn’t be able to identify signal. It provides the contrast, the background that allows us to separate one from the other.

But we have to give signal a chance. Processes to get rid of noise are all very well, but they may just take signal with them. Penzias and Wilson in 1964 tried for three years to get rid of background noise in their experiments, only to find that it contained the information that would win them a Nobel Prize.

To separate signal from noise we need to give it space. Time out. An opportunity to reflect. The time to discuss with others without an agenda – time to let our brilliant brains do what they do best – make connections that computers can’t. As yet, digital devices process brilliantly, but don’t wonder about things.

It’s Sunday. Use it to advantage.

Have a great week ahead.
