The work of preparing International Standards is normally ca

21、rried out through ISO 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work

22、. 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 Directives, Part 2. The main task of technical committees is to prepare Intern

23、ational 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 member bodies casting a vote. Attention is drawn to the possibility that some of the

24、 elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 24501 was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 5, Ergonomics of the physical environment. Licensed Copy: Wang Bin, I

Consumer products, as defined in ISO 20282-1, include home electrical ap

26、pliances, information and telecommunication products, gas-heating equipment, toys, sanitary equipment, and health-care products, many of which use auditory signals. These auditory signals can be indistinct because of the hearing loss which occurs with ageing or because of interfering sounds in the s

27、urroundings. Also, with age, our visual ability declines gradually. Auditory signals with an appropriate sound level can assist product users with auditory or visual impairment in using the product correctly and safely. This International Standard specifies methods for determining an appropriate sou

28、nd level range of auditory signals, so that all product users, including people with age-related hearing loss, can hear them properly against interfering sounds. This sound level range specification was determined, based on results of experiments in which people of all ages participated. Auditory si

29、gnals whose sound pressure level is in that range are expected to be audible and comfortably loud for most users in the presence of interfering sounds. This International Standard should be applied as appropriate to products, depending on the product type and its conditions of use. It does not apply

30、 to machines and equipment used for professional work. This International Standard adopts the principles of accessible design given in ISO/IEC Guide 71 and amplified in ISO/TR 22411.

32、ternational Standard specifies methods for determining the sound pressure level range of auditory signals so that the users of consumer products, including people with age-related hearing loss, can hear the signal properly in the presence of interfering sounds. Auditory signals, in this Internationa

33、l Standard, refer to sounds with a fixed frequency (also called beep sounds) and do not include variable frequency sounds, melodic sounds, or voice guides. This International Standard is applicable to auditory signals which are heard at an approximate maximum distance of 4 m from the product, as lon

34、g as no physical barrier exists between the product and the user. It is not applicable to auditory signals heard through a head receiver or earphones, or to those heard with the ear located very near to the sound source because of the interference of the head with sound propagation. This Internation

35、al Standard does not specify the sound pressure level of auditory signals regulated by other statutes, such as those for fire alarms, gas leakages and crime prevention, nor does it specify auditory signals particular to a communication tool such as telephones. This International Standard does not sp

36、ecify auditory danger signals for public or work areas which are covered in ISO 7731, ISO 8201, and ISO 11429. 2 Normative references The following referenced standards are indispensable for the application of this document.

41、(e.g. actuation sound of a vacuum cleaner). 3.3 interfering sound product actuation sound or living environment sound which is likely to have the greatest effect on audibility of the auditory signal to be designed 3.4 ambient noise sound other than the sound to be measured as an auditory signal or a

42、s an interfering sound at the measurement location EXAMPLE Outside traffic noise. 4 Symbols For the purposes of this document, the following symbols apply. LS,AA-weighted sound pressure level of an auditory signal, in decibels, measured using the method specified in Annex A. LN,AA-weighted sound pre

43、ssure level of interfering sound, in decibels, measured using the method specified in Annex B. LS,octlevel of the frequency band, in decibels, which has the maximum value among octave-band sound pressure levels of auditory signals, measured using the method specified in Annex A. LN,octoctave-band so

44、und pressure level, in decibels, of interfering sound at the same frequency band as LS,oct, measured using the method specified in Annex B. LS,1/3octlevel of the frequency band, in decibels, which has the maximum value among one-third-octave-band sound pressure levels of auditory signals, measured u

45、sing the method specified in Annex A. LN,1/3octone-third-octave-band sound pressure level, in decibels, of interfering sound at the same frequency band as LS,1/3oct, measured using the method specified in Annex B. 5 Range of sound pressure levels of auditory signals 5.1 General The range of sound pr

46、essure levels of auditory signals shall be determined following the procedure in 5.2 or 5.3, depending on whether the masking effect of interfering sound is taken into consideration or not. When an auditory signal with a fixed sound level is used, the level shall be selected to fall in the range spe

47、cified by application of the method. When the sound level is controllable by the user, the level shall be variable to cover the entire range. NOTE It is important for designers to consider the implication of adjustable volume controls with respect to caution signals, if the adjustable range extends

48、below the lower end specified by application of the method. An example of the record of measurement conditions and results is shown in Annex C. Some examples of measurement and range setting of the sound pressure level of auditory signals are shown in Annex D. Licensed Copy: Wang Bin, ISO/EXCHANGE C
