Noise level in dBA - The sound test standard is defined in a document called ISO/DIS 10302 or ANSI S12.11, the American National Standard for the Measurement of Noise Emitted by Small Air-Moving Devices. Sound is quantified in terms of sound pressure level, the magnitude (in dBA) of pressure fluctuation at some point in space.

Speed in RPM – the fan rotation speed measured by revolutions per minute.
