SINAD

Okay kiddo, so have you ever heard of something called "sinad"?

Well, it's a measure of how good a sound system is at playing music or other sounds without adding any extra noise or distortion.

Think of it like this: when you listen to music on a really good sound system, it sounds clear and beautiful. But when you listen to music on a bad sound system, it might sound scratchy or muffled, like there's a lot of extra noise getting in the way.

Sinad is like a way of measuring how good a sound system is at avoiding that extra noise. The more sinad a sound system has, the better it is at playing sounds without adding any extra noise or distortion.

So if you want to enjoy your music or other sounds without any extra noise getting in the way, you want a sound system with a high sinad rating!
