What sounds are loud and what sounds are quiet?

The most general way to describe it is that amplitude is related to how loud or soft the sound is. Greater amplitude causes a louder sound. Frequency, how rapidly the waves come per second, is related to the pitch of the sound. The greater the frequency the higher the pitch. Amplitude is how high and low the waves appear to be when they are graphed. Frequency is the measurement between peaks of waves of a graphed sound. It is easiest to learn and understand these differences when you look at pure sine waves of sound, sound with no harmonics or overtones. The sounds you hear in the real world are more complicated than that, but the basic principles of amplitude and frequency still apply.
