With the advent and proliferation of computer technology, many design companies are creating and using computer modeling to determine noise control requirements for extensive installations such as petrochemical plants, cogeneration facilities, compressor stations, etc. However, in order to be effective these programs require correct input data on source characteristics such as source strength, frequency characteristics, directional characteristics, and temporal variations. This paper discusses the relative merits of the current methodologies used to obtain this data including manufactured supplied data, laboratory measurement methodologies, and field measurement methodologies. Current testing standard are also reviewed.
