This present contribution reports on the results of sound level measurements in a number of locations in the city of Vienna, Austria. Thereby, a primary objective was to determine the degree to which the measurement results agree with corresponding information in the E.N.D. (Environmental Noise Directive 2002/49/EC) maps. Moreover, the relationship between the low-frequency segment of the acoustical exposure to the broad-band data was investigated. The results point to traffic as the main source of urban noise exposure. END maps appear to provide a reasonable general overview of the urban noise circumstances. However, measurement result at individual locations can considerably deviated from END data. Numeric values of low-frequency sound level range were found to be generally higher than those of the broad-frequency levels. The results revealed also a strong correlation between measurement-based L50 and NR values.
