Motorized road vehicles are the major source of noise; always responsible for creating annoyance among people. The present study is aimed to investigate the correlation between an-noyance level and different noise indices and its impact on residents/community in terms of an-noyance index. Noise and attitudinal response of local population were carried out at ten com-mercial road networks of the city. To define the noise annoyance quantitatively, a new point scale [i.e. Mean Dissatisfaction Score)(MDS)]has been used in the present study , a strong correlation
was observed between percentage highly annoyed and various noise indices.
