26、Consumer products, as defined in ISO 20282-1, include home electrical appliances, 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
27、 loss which occurs with ageing or because of interfering sounds in the surroundings. 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 Int
28、ernational Standard specifies methods for determining an appropriate sound 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 resu
29、lts of experiments in which people of all ages participated. Auditory signals 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, de
30、pending on the product type and its conditions of use. It does not apply 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. 4DIN EN ISO 24501:2011-04 EN ISO 24501:2010 (
31、E) 1 Scope This International 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
32、 this International 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 t
33、he product, as long 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
34、. This International 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 St
35、andard does not specify 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.

38、 product which incorporates the auditory signal to be designed EXAMPLE A cooling-fan noise. 5DIN EN ISO 24501:2011-04 EN ISO 24501:2010 (E) 3.2 living environment sound sound generated in the room where the consumer product which incorporates the auditory signal to be designed is used NOTE This incl
39、udes a sound generated by user behaviour (e.g. sound of water generated when washing dishes in a kitchen) or an actuation sound of some other product incorporating the auditory signal to be designed (e.g. actuation sound of a vacuum cleaner). 3.3 interfering sound product actuation sound or living e
40、nvironment 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 as an interfering sound at the measurement location EXAMPLE Outside traffic noise. 4 Symbols For the p
41、urposes 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 pressure level of interfering sound, in decibels, measured using the method specified in Annex B. LS,oct
42、level 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 sound pressure level, in decibels, of interfering sound at the same frequency band as LS,oct, measured
43、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 using the method specified in Annex A. LN,1/3octone-third-octave-band sound pressure level, in decibel
44、s, 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 pressure levels of auditory signals shall be determined following the procedure in 5.2 or 5.3, dependin
45、g 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 specified by application of the method. When the sound level is controllable by the user, the level shal
46、l 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 below the lower end specified by application of the method. An example of the record of measurement c
47、onditions 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. 6DIN EN ISO 24501:2011-04 EN ISO 24501:2010 (E) 5.2 When not considering the masking effect of an interfering sound 5.2.1 General For a case
48、 in which the masking effect of interfering sound can be ignored because its level is very low, only the users hearing-ability change which occurs with ageing is considered for setting the range of the sound pressure level of the auditory signal. The range of the sound pressure level shall be determined in accordance with either method using octave-band analysis or one-third-octave-band analysis, both of which are described in 5.2.2. For the methods for measuring the sound pressure level using octave-band ana
