Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, gov

28、ernmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC

29、 Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the membe

EN ISO 9921:2003vIntroduction The aim of standardization in the field of the ergonomic assessment of speech-communication is to recommend the levels of speech-communication qualit

32、y required for conveying comprehensive messages in different applications. The quality of speech communication is assessed for the following cases: warning of hazard; warning of danger; information messages for work places, public areas, meeting rooms, and auditoria. For some applications, direct co

33、mmunication between humans is considered while, in others, the use of electro-acoustic systems (e.g. PA systems) or personal communication equipment (e.g. telephone, intercom) will be the most convenient means of informing and instructing or exchanging information. The use of auditory warning symbol

34、s other than speech is not included in this International Standard but is covered by ISO 7731. Acoustical danger and warning signals are in general omni-directional and therefore may be universal in many situations. Auditory warnings are of great benefit in situations where smoke, darkness or other

35、obstructions interfere with visual warnings. It is essential that, in the case of verbal messages, a sufficient level of intelligibility is achieved, in the coverage area. If this cannot be achieved, non-voice warning signals (see ISO 7731, IEC 60849 and 4 in the Bibliography) or visual warning sign

36、als (see ISO 11429) may be preferable. If acoustical signals are too loud, hearing damage or environmental problems may occur (e.g. noise nuisance to dwellings near railway platforms, road traffic, airports, etc.). Good design can minimize these negative aspects. In addition, prediction methods with

37、 sufficient accuracy are useful for consultants, suppliers and end-users and may thus reduce costs of necessary adjustments after installation of a system. The communications might be directly between humans, through public address or intercom systems or by pre-recorded messages. In general, text-to

38、-speech systems are not recommended because of the low intelligibility of these systems. It is recognized that, in a general-purpose document, simple to apply and easily available tools for prediction and assessment should be described, as well as more sophisticated advanced technological methodolog

EN ISO 9921:2003INTENRATIONAL TSANDADR IS:1299 O3002(E)I SO 3002 All irhgts seredevr 1Ergonomics Assessment of speech communication 1 Scope This International Standard specifies the requirements for the performance of speech communication for verbal alert and danger signals, information message

40、s, and speech communication in general. Methods to predict and to assess the subjective and objective performance in practical applications are described and examples are given. In order to obtain optimal performance in a specific application, three stages can be considered: a) specification of the

41、application and definition of the corresponding performance criteria; b) design of a communication system and prediction of the performance; c) assessment of the performance for in situ conditions. The use of auditory warning signals other than speech is not included in this International Standard b
