abstract = "The regulations for vehicle pass-by noise are getting ever more stringent and the maximum allowable pass-by noise level is set to continue decreasing over the coming years. This forces the vehicle OEMs to develop quieter vehicles with a reduction in the noise emitted by the dominant
sources which are the tires and the powertrain. For a sports vehicle with internal combustion engine, reducing the powertrain noise poses additional challenges as the customers for such vehicles have high expectations for both interior and exterior sound quality. Quieter powertrain designs
will then limit the opportunity to meet these requirements and to develop a brand image. Sound enhancement provides an answer to these challenges: additional sound is played through the vehicle speaker system to complement the quieter powertrain sound. The sound enhancement signature is dependent
on the vehicle operating conditions (speed, throttle, and engine RPM). The system may also provide different modes of operation like a sport or a quiet mode that the driver can choose from to adapt to changing needs when driving at night, on highway, during a daily commute, etc. During the
development of vehicles with such a sound enhancement system, the focus of the powertrain sound quality engineering is then switched to the design of the sound enhancement preferences. In this paper, we present the work we have performed together with our customer to define the sound enhancement
preferences for a sport vehicle. We explain how we used vehicle benchmarking to define potential strategies for sound enhancement and how we identified the customer preferences during a jury test. We then describe how we used the jury results to define several candidates for sound enhancements
that were then evaluated directly in the vehicle using a virtual NVH prototype evaluation system.",
