LAeq, 6min of 55, 65 and 75 dB) and indoor (noise levels at LAeq, 6min of 35, 45 and 55 dB) conditions
was investigated in laboratory settings. In each experiment, 30 Japanese and 30 Chinese subjects were
requested to perform auditory (listening) and non-auditory (calculation) tasks while each noise was
presented for 6 minutes, and then to assess the disturbance caused by the noises using 5-point verbal
scales constructed by the ICBEN method. The results showed that though some railway bonus caused
by noise masking did exist for auditory task in the outdoor conditions, no railway bonus was found for
the other situations. On the contrary, in the indoor conditions, railway noise was evaluated to be a little
more disturbing to the activities than road traffic noise by the subjects in most cases. Though the
Japanese subjects appeared to be more sensitive to noises than the Chinese subjects, no systematic
difference was found between the two subject groups., https://www.jstage.jst.go.jp/article/ast/26/3/26_3_258/_article},
