Typical Sound Power Levels of Electrical & Mechanical Equipment

The following sound power levels for various rating of equipment are given for reference purpose only. Where practicable, the sound power level of the concerned equipment should be referred to the respective manufacturers (see table 11 to 14). Super low noise model of Electrical & Mechanical Systems on the market could be 6 to 9 dB(A) lower.
