Patent number: 6626041Abstract: Internal combustion engines and electric motors in motor vehicles generate, at all operating points, airborne emissions and solid-borne emissions, which are superimposed in the interior of the vehicle and perceived as engine noise by the occupants. To differentiate quantitatively between airborne and solid-borne portions of engine noise, sound measurement are made in the vehicle interior and engine compartment both with air and when the engine compartment is flooded with a gas having different acoustic characteristics than air. From analysis of the two measurements, the solid-borne portion and the airborne portion of the engine noise can be determined with a high degree of precision.Type: GrantFiled: September 18, 2002Date of Patent: September 30, 2003Assignee: Ford Global Technologies, LLCInventor: Hans Joachim Raida
