"NettetThe loudness of sound is generally measured in terms of decibels (dB). On the decibel scale, a doubling of noise energy results in an increase of 3dB. A change of 3dB has been defined as the minimum that is perceptible under normal conditions, while a change of 10dB corresponds to roughly a doubling or halving of loudness. " - How sound measured
