چکیده
Driver and passenger comfort is a major factor in the automotive industry and one important part of comfort in a vehicle represents sound quality. Sound quality can play an important role in the customer’s vehicle selection [1-3]. Furthermore, today, customers ask for more acoustical comfort and pleasant sounds [4,5]. For this reason, the development of high-quality sounds becomes more and more important [6,7] and can nowadays also be seen as an integral part of the brand strategy of many automotive manufacturers [3,8,9].
