In Response To: Capt. Patrick /Noise reduction (AL C.)

Al,

Not sure, but at cruise, you had to shout to one another to be heard over the noise...

The main source of "noise bleed" on Ricky's B31 was the Vetus vents installed directly into both the engine boxes and the side panels. With the side air installed, the Vetus vents were blocked off with sound insulation. Further reduction was accomplished by restructuring the way the that the engine boxes sat onto the deck & the addition of more sound insulation.

I think Ricky may have told me that he measured the initial intensity at around 72dB.

Best regards,

Patrick
