[QUOTE=119240;751648]I got the HP & loud BMW pipe - So where do I fit in?
Here a samples - [url]http://www.youtube.com/watch?v=MDja3aNzZhQ&feature=related[/url]
I pass inspection & have never been pulled over for the pipe - got it tested by local police 95 Dbs at 1/2 red line - I do carry the paper with me just in case :-)[/QUOTE]
At speed, ~40-mph, wind noise likely dominates what you are hearing (depends on type of fairing, helmet design and fit). The 95-db is what you are subjecting your stationary neighbors to.
Suggested sound level expose times for unprotected hearing is
85dB - 8hrs
95dB - 4hrs
100dB - 2 hours
110dB - 30 min
120dB - 7.5 min
It just a question of courtesy.
