TECHNIQUES TO REDUCE ROADWAY NOISE

■ Create    noise   barriers

■ Place limitations on  vehicle speeds

■ Introduce newer   roadway surface technologies

■ Limit times   for heavy-duty  vehicles

■ Create    computer-controlled traffic flow    devices that    reduce  braking and

acceleration,   and implement   changes in  tire    designs

TECHNIQUES TO REDUCE AIRCRAFT NOISE

■ Develop   quieter jet engines

■ Reschedule    takeoff and landing times

TECHNIQUES TO REDUCE INDUSTRIAL NOISE

■ Create    new technologies    in  industrial  equipment

■ Install   noise   barriers    in  the workplace

Residential noise, such as power tools, garden equipment, and loud
entertainment equipment, can be controlled through local laws and enforcement.

RELEVANT LAW
