An extra 3db is twice the power[/QUOTE]
I was taught 6dB was double....
Anyway Hampton Downs hosted the classic and post-classic bikes this Labour Weekend. The pom bikes (and sidecars) were noticeably and painfully louder than their 70s Japanese racing counterparts. I would have thought that many of them were in the 100dB + zone so what is the policy at HD, and is there a hard and fast one?
I have never felt the need to put fingers in ears with American V8 cars at a few paces but these old Nortons, Triumphs etc would tweak your eardrums in pitlane as they roared down the straight or warmed up in pitlane. It was one time I would have liked noise restrictions to be enforced.
