Based on investigation of built highway noise barriers in Jiangsu province, the effect of several factors, including equivalent frequency, traffic flow, etc, on insertion loss of highway noise barriers were analyzed, and the revision was carried out. The results show that the sound source model reflecting characteristic of traffic noise is the key to assess acoustic performance of noise barrier. Meanwhile, there were some construction defects on a few of noise barriers, leading to sound leakage and poor acoustic performance.
