Abstract
A method for evaluating noise of a glass run of an automobile door includes: detecting oscillation of the door glass by a sensor for the door glass and then storing the oscillation as an oscillatory wave form of the door glass and detecting oscillation of the frame by a sensor for the frame and then storing the oscillation as an oscillatory wave form of the frame, with the glass run coupling to the automobile door; synthesizing the oscillatory wave form of the door glass and the oscillatory wave form of the frame, picking out relative oscillation of the door glass in relation to the frame and storing the relative oscillation as a synthesized oscillatory wave form; making oscillation corresponding to the synthesized oscillatory wave form by an oscillator and oscillating the door glass with the automobile stopped; and detecting sound of the oscillation by a microphone.
