WebAug 22, 2024 · The higher the frequency, the higher the pitch of the sound. You can measure the frequency of a sound wave by counting the number of complete waves that pass a certain point in a certain amount of time. For example, if you count 20 waves in one second, the frequency of the sound is 20 Hz. To measure the frequency of a sound, you need a … WebYou need to use about 10 watts to make them agree it now sounds twice as loud. So we use decibels (dB) to measure loudness: +10 dB means 10× the intensity. +20 dB means 100× …
