This study proposes a comprehensive noise abatement programme following the best practicable and economical option (BPEO) for implementation in metro city like Delhi for reducing annoyance and ill effects of traffic noise. It reviews potential applications of noise control barriers and vegetation for reducing road traffic noise and presents a design morphology and decision matrix using TOPSIS (Technique for order preference by similarity to ideal solution) approach for selection of appropriate sound barriers.
