The 1975-76 national study of railway noise in Great Britain combined a noise measurement program and a social survey of the reactions of nearby residents to railway noise. The study utilized a complex probability sample of 2010 addresses grouped in sets of 5 adjacent addresses into 403 compact segments in 75 areas each approximately one mile long. Each of the 403 clusters of dwelling units became a physical noise measurement site. At these sites a total of over 3500 analog recordings of train pass-bys were made. For each pass-by the A-weighted equivalent sound level (Leq) was measured from these recordings using a dosimeter. Other A-weighted noise measures were read from level recorder traces. These noise measures together with railway operating timetables were used in a complex computer program to construct 10 descriptors of the railway noise environment for each of the 403 noise measurement sites. The noise measurements were preceded by the social survey interviews. To date the railway noise data have been summarized with ten alternative environmental noise indices representing five concepts in noise index construction. The indices are evaluated in the paper in terms of the closeness of their relationship to annoyance.
