Roadway noise - Wikipedia Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise which increases with higher vehicle speeds.

CAUSES AND SOURCES OF AUDIBLE NOISE IN ELECTRIC MOTORS James R. Hendershot, Jr. MAGNA PHYSICS DIV. TRIDELTA INDUSTRIES INC. 100 Homestead Ave. Hillsboro, OH 45133 ABSTRACT The increasing pollution caused by noise has prompted extensive efforts to either eliminate, sup- press, dampen or insulate the electro/magnetic Sound Power Pressure - Nidec Sound instruments measure only sound pressure; this pressure varies depending on the surroundings. To calculate sound pressure from sound power, one must consider all the variables that affect sound pressure. The relationship between sound power level (sound energy emitted by the motor and sound pressure (what is heard) at a specific location. A Short Guide On Motor Electrical Noise Reduction - Kerry D.
