Norme 94 décibels en 2011

Citation :

Le bruit... Préparez-vous à 94db!

On part le débat...

L'association des motocyclistes américains vient de légiférer sur le bruit acceptable pour les courses. 94db en 2011 pour tous. Je crois que les pros AMA et FIM seront déjà à 94db l'an prochain.

AMA Congress Convenes, Passes New Lower Sound Rules

PICKERINGTON, Ohio--The 2008 American Motorcyclist Association (AMA) Congress gathered October 9-11 to consider numerous issues affecting amateur motorcycle competition and recreational riding in the United States. Rule changes passed by AMA Congress included the regulation of motorcycle sound levels at competitive events, motocross class advancement and new event types for road riders.

In all, AMA Congress considered 83 rule proposals at the 2008 annual meeting, 47 of which were passed or amended for possible ratification by the AMA Board of Directors. In deference to the needs of local AMA organizers, the AMA and original equipment manufacturers, most rules adopted by the 2008 AMA Congress will not take effect before 2010, at the earliest.

Most notably, the 2008 AMA Congress passed a 94 dB(a) standard for all amateur and Pro-Am motocross and off-road competition, effective in 2011. The new standard will not apply to land-speed racing, speed trials or drag-racing events.

The new level mirrors both the 2009 standard for professional motocross and Supercross racing in the United States, as well as the level mandated by the FIM (Federation Internationale de Motocyclisme), which governs international motorcycle competition. Currently, sound limits for amateur motorcycle competition are 99 dB(a) for closed-course competition and 96 dB(a) for cross-country racing.

"Few issues contribute more to misunderstanding and prejudice against the motorcycling community than excessively loud motorcycles, and this measure addresses the issue head-on," said AMA President and CEO Rob Dingman. "This standard is already in place for professional and international competition, making this one of the most cost-effective and easy-to-implement solutions to the sound problem. That said, AMA Congress understands that amateur competitors may need more time to adopt this new standard and wisely established a reasonable deadline for compliance."

Also at the meeting, AMA Congress passed revised advancement procedures for amateur motocross racers, which are designed to be more equitable to C-class riders poised to advance to the B level.

On the road-riding side, the AMA Congress considered several proposals, including two that develop new types of events. One is the Bonus Hunt, which is part scavenger hunt and part road enduro. The other provides a more detailed procedure for the popular Vintage Motogiro event, which gives owners of vintage and antique motorcycles a chance to meet and show off their unique machines.
