Details
This standard provides certain reference values to be used for acoustical and vibratory levels. Levels,
when used in this standard, refer to a descriptor of mathematical calculation in which a ratio is used. The
reference value is the denominator of that ratio. Reference values are stated in the International System
of Units (SI). The descriptor of most acoustical levels is the decibel, abbreviated "dB". Levels are equal to
ten times the common (base-10) logarithm (abbreviated lg) of an appropriate nondimensional ratio of a
variable quantity (in the numerator) to a reference value of the same kind (in the denominator). The
multiplier ten is used when the numerator is a power or power-like quantity (such as the time average of
the square of a time-varying sound pressure or vibration acceleration) or an energy-like quantity (such as
sound exposure).
