| Summary: | This study explores acoustic material design strategies to address environmental noise transition due to increased electric vehicle (EV) usage in Bandung, focusing on Tugu Simpang Lima Office Building. The main objectives are to assess day- night noise levels in the office, identify differences in equivalent daytime noise levels produced by EVs and internal combustion engine (ICE) vehicles through simulations, and formulate acoustic material design strategies while evaluating the need for material standard updates to ensure effective noise reduction in EV- dominated traffic environments. The method includes direct noise level measurements at the study site, analysis of noise emissions from single vehicle sources, and software-based simulations to evaluate noise impacts from 100% ICE, 50% ICE + 50% EV, and 100% EV scenarios. Various materials, such as single- pane glass, double-pane glass, laminated glass, brick + plaster, and concrete, are evaluated based on daytime noise levels (Ls) simulations to determine optimal noise reduction design strategies. The study's noise maps results indicate that the transition from ICE to EV traffic significantly reduces noise levels in the office lobby, with noise levels decreasing from 71.2 dB(A) for 100% ICE vehicles to 65.8 dB(A) for 100% EVs, showing a 5.4 dB(A) reduction. In Scenario 2, noise levels further decrease to 55.3 dB(A) for F route and 63.7 dB(A) for A+D route with 100% EV, a reduction of 15.9 dB(A) and 7.5 dB(A) respectively compared to 100% ICE. The material design strategy simulations show that thinner materials can be used without compromising acoustic insulation quality when traffic consists predominantly of EVs.
