| dB |
Term representing a ratio of two quantities; one being the way sound is measured and the other being a reference sound level that corresponds to the fainter sounds heard by the human ear. The greater the dB, the higher the sound. If the dB is changed by about 10 units or more, the sound seems twice as loud.
