22、al standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internatio
23、nal organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. IS0 collabo- rates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Drat International Standards adopted by the technical commit
24、tees are cir- culated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Intemational Standard IS0 11690-1 was prepared by Technical Committee ISOTTC 43, Acoustics, Subcommittee SC 1 , Noise. IS0 11690 con
25、sists of the following parts, under the general title Acous- tics - Recommended practice for the design of low-noise workplaces containing machinery: - Part 1: Noise control strategies - Part 2: Noise control measures - Part 3: Sound propagation and noise prediction in workrooms Part 1 is the centra
26、l document in the series. Patts 2 and 3 give additional technical and explanatoty information. It is therefore recommended to start with part 1.

27、ion Most of the existing Intemational Standards prepared in ISOTTC 43/SC 1 specify methods for measurement and/or evaluation of noise. The final objective of IS0 11690, however, is noise reduction. A number of noise control measures are offered. However, in order to be effective, the most appropriat
28、e noise control measure) should be chosen for a given situation. It is important when non-acoustic engineers are involved in noise control practice for these engineers to have a basic knowledge of noise emission and propagation characteristics and to understand the basic principles of noise control.
29、 To assist in the development of noise control in the workplace, it is essen- tial that the information contained in these recommended practices is dis- seminated through Intemational Standards. In order to reduce noise as a hazard in the workplace, individual countries have produced national legisl
30、ation. Generally, such national legislation requires noise control measures to be carried out in order to achieve the lowest reasonable levels of noise emission, noise immission and noise ex- posure, taking into account: - known available measures; - - - the state of the art regarding technical prog
31、ress; the treatment of noise at source; appropriate planning, procurement and installation of machines and equipment. This part of IS0 11690, together with the two other parts in the series, out- lines procedures to be considered when dealing with noise control at workplaces, within workrooms and in
32、 the open. These recommended prac- tices give in relatively simple terms the basic information necessary for all parties involved in noise control in workplaces and in the design of low- noise workplaces to promote the understanding of the desired noise control requirements. The purpose of the IS0 1
33、1 690 series is to bridge the gap between existing literature on noise control and the practical implementation of noise control measures. In principle, the series applies to all workplaces and its main function is: - to provide simple, brief information on some aspects of noise control in workplace
34、s; - to act as a guide to help in the understanding of requirements in stan- dards, directives, text books, manuals, reports and other specialized technical documents: iv STDSBSI BS EN IS0 LLb7O-1-ENGL 1997 Lb24bb9 Ob3512b 7b3 EN IS0 11690-1 : 1996 - to provide assistance in decision making when ass
35、essing the various measures available. The IS0 11690 series should be useful to persons such as plant person- nel, health and safety officers, engineers, managers, staff in planning and purchasing departments, architects and suppliers of plants, machines and equipment. However, the above-mentioned p
36、arties should keep in mind that adherence to the recommendations of the IS0 11690 series is not all that is necessary to create a safe workplace. The effects of noise on health, well-being and human activity are many. By giving guidelines for noise control strategies and measures, the IS0 11690 seri
37、es aims at a reduction of the impact of noise on human beings at workplaces. Assessment of the impact of noise on human beings is dealt with in other documents.

39、and noise exposure). It is applicable to all types of workplaces and ali types of sources of sound which are met in workplaces, including human activities. It includes those important strategies to adopt when buying a new machine or equipment. This part of IS0 11690 deals only with audible sound. -
