Noise Effects and Management

More than 50 years have passed since the Tokaido Shinkansen railway, the first high-speed railway, opened in 1964. The network of Shinkansen lines has been continuously expanded in Japan: the Hokuriku and Hokkaido Shinkansen lines were partially opened in 2015 and 2016, respectively. To preserve the living environment and to protect human health, the Japanese government enacted the Environmental Quality Standards for Shinkansen Superexpress Railway Noise in 1975. Many social surveys on community response to Shinkansen railway noise and vibration have been conducted. A part of these surveys data have been accumulated in Socio-Acoustic Survey Data Archive. We reanalyzed data from seven social surveys along six Shinkansen lines carried out from 1995 to 2013. The number of response to the question of daily activities was from 5441 to 1997 samples. TV/radio listening disturbance was greater than other listening disturbances at the same noise level. The evaluation of awakening exceeded 10% above the night time noise level of about 45 dB. Through the comparison between the survey, it was indicated that the effect of differences in the number of train service per day.
