How is Sound Measured? | Noisy Planet
Another important and easily measured factor is sound intensity, or volume. We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels. Decibels (dB) are named in honor of Alexander Graham Bell, the inventor of both the telephone and the audiometer. An audiometer is a device that measures how well a ...
