WebHow Decibel Levels Are Measured. To measure the noise level of different sounds, we use a measurement unit called the decibel (dB). It represents a sound’s intensity. To measure a sound’s frequency, we use the hertz (Hz). Each time a sound’s decibel level increases by 10, its intensity multiplies by 10.
