Abstract

U ovom radu prikazan je problem buke u urbanim sredinama s naglaskom na buku od cestovnog prometa. Pokazano je kako se većim udjelom električnih vozila ta buka može značajno smanjiti. Međutim, u tom slučaju javlja se problem nedovoljne čujnosti električnih vozila koji se odražava na sigurnost pješaka u prometu. Prema dosadašnjim istraživanjima vidljivo je da bi se problem riješio dodavanjem zvuka pri niskim brzinama. Obzirom da većina ljudi zvuk motora s unutarnjim izgaranjem smatra najprihvatljivijim zvukom za električne automobile, provedeno je slušno ispitivanje sa sedam različitih zvukova motora s unutarnjim izgaranjem. Najbolje ocijenjeni zvukovi isprobani su na sustavu ugrađenom u stvarno električno vozilo.

Abstract (english)

This paper provides an insight into the problem of noise in urban areas, specifically traffic noise. It is shown that the increased share of electric vehicles can significantly reduce trafic noise. However, the proposed solution leads to the problem of insufficient loudness of electric vehicles, jeopardising pedestrian safety. According to previous studies, the above-mentioned safety issue can be solved by adding artificial sound to electric vehicles. The sound of internal combustion engine is shown to be the most appropriate for electric vehicles. Therefore, in this paper, an aural test is performed on 36 subjects in a laboratory in order to show which of the seven recorded ICE motor sounds would be most suitable. The best rated sounds have been tested on the sound system of a real electric vehicle.
