The Nanjiang Industrial Park, which is located near the north branch of the Peal River, has many metals machining, plating factories. The sound environment around Nanjiang Industrial park was investiaged to assess the noise impacts to the surrounding areas. Result showed that the noise from the Industrial Park had certain impacts to the surrounding areas. During construction period, the noise had exceeded the national standard and had certain impacts to the surrounding villages and primary schools with the maximum impact at night. During operation period, noise level in three villages and one primary school had exceeded the national standard 2 and 1 respectively. The percentage of exceeding the national standard were 7.5%~17.2% in daytime, and 19.2%~33.3% at night.
