Indonesian users' active sound design preference for armored electric SUV interior

Abstract

This paper explores the potential of Active Sound Design (ASD) in the Indonesian electric vehicle (EV) market, where there are a projected 2 million EV users by 2030. While ASD is a crucial aspect in addressing the lack of engine sound in EV, it is still developing and mainly focused on certain regions. The ASD approach includes active noise control (ANC) to reduce unwanted noise inside the cabin and engine sound enhancement by inserting additional engine sound through the speakers. The study evaluates the original EV stimulus, ANC stimulus, and two ASD stimuli (ICE and futuristic) of an armored electric SUV using an audiovisual car cabin soundscape simulator. The results show that the ANC technology (improved EV with noise filter) is the most preferred stimulus with the highest comfort value perceived by the participants. These insights can help EV manufacturers optimize their sound design solutions for future EV productions in Indonesia.
