Internal noise
The noise in the cabin is also improved in order to increase pilot and passengers comfort.
Measures have been realised on a standard aircraft and give the following mean levels :
81.3 dB SIL4

in hover inside ground effect
86.1 dB SIL4 in cruise flight at 120 kts

The method of sound level measurement used is Speech Interference Level (dB SIL4). This is the arithmetic
average of 4 octave (0.5, 1.0, 2.0 and 4.0 kHz) levels specified in dBlin (linear decibels). This particular set of
octaves corresponds to the human voice frequency range and thus allows to evaluate the interference with
passenger communication.
