| Abstract(J) | 本論文は，R51-03試験に基づくStep 1と規制値等の既知データのみで構築可能なStep 2からなる車両音源モデルを提示し，M1/N1で検証して音響パワーレベル差0.5 dB以内を示し，将来予測・曝露評価に有効であることを示した。 Translation |
| Abstract(E) | We propose a two-step method to build vehicle sound source models for road-traffic noise prediction. Step 1 identifies a three-component model (tire/road, mechanical, dynamic) from R51-03 pass-by tests. Step 2 eliminates testing by combining regulatory pass-by levels with vehicle specifications, using PMR-based normalization and a regression to estimate time-averaged sound power during urban driving. Across M1, N1 vehicles, Step 2 agreed with Step 1 within 0.5 dB in mean Lw, demonstrating practicality for rapid updates under mixed regulatory cohorts and future fleet shifts. |
