Annoyance reactions due to railway noise

Social survey studies to assess the presence of general annoyance were made in different areas exposed to railway noise. The results show that an increase in the number of passing trains increases annoyance up to a certain level, after which a levelling off takes place. Hence, there is no real annoyance in areas exposed to a maximum of 50 train passages/24 hours until the noise level reaches above 85 dB(A). If, on the other hand, train passages are 60 or more, annoyance increases according to the dB(A) level.
