The experience of the vehicle sound is increasingly an important factor, which significantly influences the driver's contentment. This aspect is covered by the NVH section of the car manufacturers. The NVH quality of vehicles has been a very vital task for acoustic engineers for more than 20 years. However, up to now they have not been developing target sounds, but have rather only been working on 'symptoms'. Of course, the process of troubleshooting and the elimination of disturbing noise components is indispensable. However, does the avoidance of unwanted noise phenomena mean that the remaining sound is adequate and ideal for the respective vehicle? Sound and vibration must not be only considered as disturbing elements regarding the NVH-comfort; they can be used to develop an acoustical and vibrational environment which influences the customer's contentment positively. The creation of sounds which give the impression of high product quality helps manufacturers to stand out against their competitors and to meet the increasing demands of the customers. Sound quality considerations and target sound development require multi-dimensional approaches integrating new and interdisciplinary methods. The presented approach in connection with a sound simulation system installed in a drivable vehicle allows the determination of target sounds. The advantages of EVE approach in connection with the mobile sound simulation system are - Development of the most marketable products - Fast implementation and efficient testing of new sounds with respect to the vehicle's target sound - Target sound development based on the most convincing evaluation data - Easy verification of new products with respect to the readiness for market, even for non-acoustic aspects. The test design of EVE is flexible; the procedure of free evaluations of vehicle noise while the test person is driving can be extended to benchmarking tests and interactive sound design. The implication of such test design extensions have to be studied elaborately in order to avoid bias effects and artefacts caused by new test designs. Furthermore, the sample has to be selected carefully with respect to the intended target group in order to guarantee the external validity and the possibilty of generalizing the test results. EVE in connection with the presented mobile driving simulator reliably guarantees the determination of target sounds with high external validity because of the authentic test environment and test situation.
