Abstract
Vehicles with improved driving comfort are produced in order to be more competitive in the developing automotive sector. One of the parameters that affect driving comfort is the acoustic performance of the vehicle in the cabin. The most explicit sounds that affect the cabin area are road, wind, wheel, trim, and engine sounds. In this study, vibration accumulation on the body of the vehicle has been determined. Accordingly, the vehicle body has been improved with isolation, and sound assessment has been done inside the cabin. It has been determined that the acoustic performance is improved with the isolation improvements in the vehicle. Afterward, the effect of engine types, different body types for the same kind of engine, wheel rim effects, and engine mounts on the interior sound level is examined. In the examination of acoustic performance, it is determined that the articulation index is determinant rather than the sound level. The isolation effect on the vehicle body and the impact of the engine mounts are evaluated by the jury tests.
