Helicopter Noise Emission research.
Guys,

I need a push in the right direction to find out specific information regarding the Db ratings of various helo types. Is anyone aware of links pertaining to research done on this previously?

I have no doubt there is lots out there but I would be very interested in the noise signatures of Bell 206L, 205, KA32, CH107, CH234 and Mil 26.

Please and thankyou.

Steve
