Noise Control Safety Standards come into play when the generation of noise cannot be avoided and must be addressed in some manner. Common solutions include the use of silencers or enclosures/cabins. Noise control is vital to protecting the safety of workers, as well as the comfort levels of those outside the workplace but still close enough to be affected.
This information sheet discusses how noise measurement and control depend upon the individual characteristics of the prime mover, gear unit, and driven machine, as well as their combined effects in a particular acoustical environment. It indicates certain areas that might require special attention. This document is a revision of AGMA 299.01 to include updated references and a discussion of Fast Fourier Transform analysis.
This Standard provides guidance on noise and vibration control in respect to construction, demolition and maintenance sites. This Standard also provides guidance for the preparation of noise and vibration management plans, work method statements and environmental impact studies.
Sets outs requirements and guidance on the management of noise control in occupational settings and applies to all types of workplaces and to all types of sounds.
This International Standard deals with the practical selection of silencers for noise control in gaseous media. It specifies the acoustical and operational requirements which are to be agreed upon between the supplier or manufacturer and the user of a silencer. The basic principles of operation are described in this International Standard, but it is not a silencer design guide. The silencers described are suitable, among others, for attenuating system noise and preventing crosstalk in heating, ventilation and air-conditioning (HVAC) equipment; for preventing or reducing sound transmission through ventilation openings from rooms with high inside sound levels; for attenuating blow-off noise generated by high-pressure lines; for attenuating intake and exhaust noise generated by internal combustion engines; and for attenuating intake and outlet noise from fans, compressors and turbines. They are classified according to their types, performance characteristics and applications. Active and adaptive passive noise-control systems are not covered in detail in this International Standard.
This document defines the procedures for noise control of primarily open plants and the requirements on equipment suppliers for reporting and testing of noise. It is applicable to the following: — specification of procedures for noise control during engineering of a new plant and modification/extension of existing plants (construction and commissioning noise procedures are outside the scope of this document); — definition of responsibilities of parties involved, viz. “end-user”, “engineering contractor” and “equipment supplier”; — description of general procedures to arrive at noise requirements for individual equipment, based on overall noise requirements for the plant. Input to purchase specifications is presented i n REF Annex_sec_A \r \h Annex A . A schematic flowchart, reviewing the noise control process, is presented in REF Annex_sec_B \r \h Annex B 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000C00000041006E006E00650078005F007300650063005F0042000000 and a summary of action items is presented in REF Annex_sec_C \r \h Annex C 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000C00000041006E006E00650078005F007300650063005F0043000000 . An example of an equipment noise data sheet is presented in REF Annex_sec_E \r \h Annex E 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000C00000041006E006E00650078005F007300650063005F0045000000 .
This International Standard deals with the performance of enclosures and cabins designed for noise control. It outlines the acoustical and operational requirements which are to be agreed upon between the supplier or manufacturer and the user of such enclosures and cabins. This International Standard is applicable to two types of acoustic enclosures and cabins, as follows. Cabins for noise protection of operators: free-standing cabins and cabins attached to machines (e.g. vehicles, cranes). Free-standing enclosures covering or housing machines: enclosures with a fraction of acoustically untreated open area of less than 10 % of the total surface are the main subject of this International Standard. In this International Standard, emphasis is put on lightweight constructions. However, thick, massive structures as, for example, brick walls, are not excluded. Enclosures and cabins with more than 10 % open and untreated area belong to the category of partial enclosures. They are not the subject of this International Standard. A third type of enclosure, integrated enclosures which form a part of the machine and are firmly attached to it, is not the subject of this International Standard.
ISO 17624:2004 deals with the effectiveness of acoustical screens. It specifies the acoustical and operational requirements to be agreed upon between the supplier or manufacturer and the user of acoustical screens. ISO 17624:2004 is applicable to the following types of acoustical screens: free-standing acoustical screens for offices, service areas, exhibition areas, and similar rooms; acoustical screens integrated in the furniture of such rooms; portable and removable acoustical screens for workshops; fixed room partitions with more than 10 % of the connecting area open and acoustically untreated. Walls of partial acoustic enclosures and cabins which, together with the room boundary surfaces, also partition a room and provide more than 10 % open and acoustically untreated area, are also treated as acoustical screens. ISO 17624:2004 is not applicable to cabinet walls and similar multi-layer walls whose thickness exceeds 0,2 m, nor to banners and other types of suspended baffles.
