THE CONTENT OF THIS AUSTRIAN STANDARD AGREES WITH ISO/DIS 3746-1976, AND DESCRIBES A PROCEDURE FOR DETERMINING THE NOISE OUTPUT FROM TECHNICAL NOISE SOURCES IN SITU. THE OUTPUT LEVEL OF THE NOISE SOURCE IS DETERMINED AS THE A-EVALUATED LEVEL FROM MEASUREMENTS OF THE A-EVALUATED SOUND LEVEL AT PRESCRIBED MEASURING POINTS (MICROPHONE POSITIONS). THIS PROCEDURE IS PARTICULARLY SUITABLE FOR DETERMINING THE NOISE EMISSION FROM STEADY NOISE SOURCES WHICH CANNOT BE MOVED INTO A PARTICULAR MEASURING ENVIRONMENT. IT SHOULD BE USED IN THOSE CASES IN WHICH AUSTRIAN STANDARDS S 5031 AND S 5034 CANNOT BE USED OR WOULD BE TOO COSTLY.
