Sound intensity level (SIL) or acoustic intensity level is the level (a logarithmic quantity) of the intensity of a sound relative to a reference value. It is denoted LI, expressed in nepers, bels, or decibels, and defined by • I is the sound intensity; • I0 is the reference sound intensity; NettetThe sound intensity level L(x) in decibels of a rock music concert a distance x metres away from the stage is modelled by the equation L(x)= a+ bln(x) where a and b are real constants.
