The quantity, L W A,c (formerly called L W Ad) may be computed from the sum of L W A,m and K v.K v is the statistical adder for computing upper-limit of A-weighted sound power level.L p A,m is the mean A-weighted sound pressure level measured at the operator position (rounded to the nearest 0.5 dB).L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.05 B.Learn more Acoustic Performanceĭeclared noise emission values in accordance with ECMA-109 macOS Mojave brings new features inspired by its most powerful users, but designed for everyone. MacOS is the operating system that powers everything you do on a Mac.
