The electrification of powertrains in road vehicles renders new interior soundscapes. The large amount of harmonics that is present in such kind of noise and the wide frequency band they spread, make the design and attainment of sound quality targets a challenging task. This paper aims at proposing a set of numerical and experimental procedures to enhance the sound quality of pure-electric-driven powertrain-induced noise, as perceived in the passenger cavities of vehicles. Relevant frequency-domain sound quality metrics are concurrently optimized, giving rise to compromise solutions, which are attained via active control. Computer simulations of two active sound quality control algorithms, which are simultaneously applied over a realistic powertrain-induced noise, and the corresponding assessment of sound quality metrics, demonstrate that it is possible to design and implement such targets in pure-electric-driven, powertrain-induced noise, thus helping the designer to solve NVH issues related to these kind of periodic disturbances.
