Differences that matter

Do I weigh less after a haircut?

Logically, I have less mass so indeed, I must weigh less—though the resolution of my scale isn't fine enough to measure the difference.

And therein lies a problem. On the one hand, I can see the change that has occured, yet I cannot measure it. If I were to use a different measurement method, like a measurement caliper recording the length of my hair, then it'd be a snap.

Which brings me to an interesting juncture. Intellectually we can agree it is not possible to hear the difference between 0.01% THD and 0.001% THD, yet changes to a circuit that reduce THD by this factor of 10 are almost always audible.

Which means, of course, we're measuring the wrong thing. Instead of looking at the results that sonically matter—let's imagine slew rate changes—we can begin to use our measurement equipment to design sonically superior products.

We just need to know where to look.
