Acoustics. Recommended practice for the design of low-noise machinery and equipment - Planning Ingestion-build-46800 • State timing1 Scope This International Technical Report is an aid to understanding the basic concepts of noise control in machinery and equipment. The recommended practice presented here is intended to assist the designer at any design stage to control the noise of the final product. Methodical development of products was chosen as a basis for the structure of this document (see Clause 4). The list of design rules given in this International Technical Report is
