Audio system measurements are a way for us to know how good a speaker or audio system is. They help us to know how loud it can get, how much bass or treble it has, and how well it will sound when we are playing music on it. To measure these things, we use something called an Audio Analyzer. This is a special device that looks like a computer, but it's actually measuring sound. It records different frequencies and sound levels so we can see how the sound is doing. With the right measurements, we can figure out which system or speaker will give us the best sound.
