Motorcycle Noise

For many communities excessive sound from motorcycles and other vehicles is a problem.  This website is intended to give resources for vehicle noise control.  The growing popularity of motorcycles, both on road and off road, and recreational vehicles such as ATV’s and watercraft, have necessitated attention on minimizing the unwanted sound from these vehicles.

DPS Technical is very involved in helping to minimize unwanted sound or nuisance noise from vehicles. We are internationally recognized for our efforts to minimize the disturbance from unwanted vehicle sound and our activities to study, educate, and assist in regulation enforcement programs.

We are well qualified to perform vehicle sound measurement for vehicle manufacturers, muffler manufacturers and to perform field sound measurements in communities and at recreational facilities such as racetracks or off highway riding areas.  We frequently work in close association with our clients’ acoustical teams in developing methods for noise control.

DPS Technical has a recognized training curriculum for vehicle sound measurement for civilians to assist in sporting event vehicle sound reduction for sporting regulation enforcement.

DPS Technical. has a recognized training program for land managers and the law enforcement community.  This training program often qualifies for POST training credit. (More specific details are available on our vehicle noise control dedicated website.)
