On a simple technique to measure the airborne noise in a car interior using substitution source

From various methods of measuring noise in a motor vehicle, a technique to separate the airborne and structure-borne noise is of interest as an important measure to improve the noise control treatment. This paper proposes a simple technique to measure the ontribution of the airborne noise in a v...
