Air borne noise

The airborne noise of the engine is measured as a sound power level according to ISO 9614-2.
The results are presented with A-weighing in octave bands, reference level 1 pW. Two values
are given; a minimum value and a 90% value. The minimum value is the lowest measured
noise level. The 90% value indicates that 90% of all measured noise levels are below this
value.
