Sound pressure level is the physical intensity of a sound. The decibel level of a signal can be expressed as, L = 10 log (S / Sref) (1), S = signal - intensity or power level (signal unit), Sref = reference signal - intensity or power level (signal unit). Decibels represent the amplitude of a sound. If the whisper is 30 dB, the measure is 60 dB for everyday conversation, and the motorcycle motor is running 95 dB.
