This International Standard is the frame standard introducing the basic group, ISO 11201, ISO 11202, stations and other specified positions. It gives guidance for: — facilitating the writing of noise test codes; — providing physical explanations of this noise emission quantity compared to other noise quantities (see 4.1 to 4.3); — comparing the different measurement methods offered by the group (see Table 1); — facilitating the choice of the most appropriate method(s) in typical practical situations (Clause 6). This International Standard is largely based on flow charts and tables. Case studies are described. The guidance given applies to airborne sound only. It is for use in noise testing, in general, and in the preparation of noise test codes, in particular. A standardized noise test code is intended to select standards from the ISO 11201, ISO 11202, ISO 11203, which give detailed requirements on mounting and operating conditions for the particular family, as well as the location of the work station(s) and other specified positions as prescribed in these International Standards. The data so obtained can be used for the declaration and verification of emission sound pressure levels, e.g. as specified in ISO 4871.[3]

This SAE Recommended Practice sets forth the instrumentation, environment, and test procedures to be used in measuring the silencer system effectiveness in reducing intake or exhaust sound level of internal combustion engines. The system shall include the intake or exhaust silencer, related piping, and components. This procedure is intended for engine-dynamometer testing and is not necessarily applicable to vehicle testing (see Appendix A). The effect of the exhaust or intake system on the sound level of the overall machine must be determined using other procedures. This procedure may be successively applied to various silencer configurations to determine r

This SAE Recommended Practice sets forth the equipment, environment, and test procedures to be used in measuring sound levels of engines. The purpose is to provide a uniform method of measuring the maximum acoustical radiation from the exterior surfaces of an engine under representative engine operating conditions. The measured sound levels will be useful in development of engines, comparison of engines, and installation of engines in various applications. The correlation of the measured engine sound levels to the various application sound levels will have to be developed.

This International Standard specifies the essential characteristics of a test surface intended to be used for measuring vehicle and tyre or road noise emissions. The surface design given in this International Standard — produces consistent levels of tyre or road sound emission under a wide range of operating conditions including those appropriate to vehicle sound testing, — minimizes inter-site variation, — provides minor absorption of the vehicle sound sources, and — is consistent with road-building practice. NOTE For the purposes of this International Standard, the terms noise and sound are used interchangeably.
