I seem to remember either Vertiflite or The Journal of the American Helicopter Society carrying a comprehensive feature on comparative helicopter noise levels about 3 or 4 years ago. You might want to try contacting the American Helicopter Society's publications team - I'm sure they'll know which back issue you need.
