Hyundai tests vehicles on noise simulator

Korea based automotive major, Hyundai, is testing its vehicles on a Noise Vibration Harshness (NVH) simulator. The desktop NVH Simulator realistically simulates the noise and vibration of a vehicle through use of an interactive driving environment. The simulator has a computer, a steering wheel, pedals and two additional screens installed in an actual vehicle or mounted on a desk to give instant and realistic reproduction of noise and vibration effects. One screen shows a virtual road with all the bends, scenery, single lane roads etc. On the second screen, engineers can select and change specifications of the virtual vehicle such as engine type, gearbox, exhaust and wind noise ? all of which contribute towards the total sound from the vehicle. Thus the virtual, in-car testing allows automotive designers to experience first-hand the noise and vibration environment within vehicles, before they’ve been fully built. Upon completion of tests, the vehicles are modified to meet expected noise and vibration requirements.
