Abstract An inventory of noise sources in these circuits was conducted at a number of steelworks. Measurements were made on the blast-furnace lines, on the agglomerating or coking units and on the oxygen supply system. The main sources of noise were fans and control valves, where sound levels often exceeded 85dB(A). Other external noise sources were identified, such as the air intakes of the fans and compressors (sound level above 85dB(A) at 1m). The piping was not an important source of radiation: the level of radiated sound was generally below that of ambient noise.
