20、ion People are surrounded by various consumer products: home electrical appliances, information and communication products, office-automation equipment, gas-heating equipment, toys, sanitary equipment, health-care products, cameras, etc. Auditory signals of such products must be designed so that the

21、 user can easily hear the signals in various circumstances where the product is normally used, and understand the objective and meaning of signalling. This International Standard has been developed for improving the usability and accessibility of auditory signals used in such consumer products, ther

22、eby improving the products themselves when they are used by all people, including those with visual impairments and older people with age-related hearing impairments. Older people include those aged 65 and above for whom age-related changes of hearing become obvious. The auditory-signal patterns spe

23、cified in this International Standard were selected based on results of experiments in which people of different age ranges and with different levels of visual impairment participated. Regarding the signals, it was confirmed that the purpose of signalling was easy for listeners to understand and tha

24、t the signals were not easily confused with signals in other signal categories. This International Standard adopts the principles of accessible design presented in ISO/IEC Guide 71 and amplified in ISO/TR 22411. DIN EN ISO 24500:2011-02 EN ISO 24500:2010 (E) 4 1 Scope This International Standard spe

25、cifies the auditory signals used as a means of feedback for operations or conditions of consumer products when used by a person with or without visual or auditory impairment. It is intended to be applied as appropriate to such products depending on the product type and its conditions of use. It is a

26、pplicable to auditory signals of a fixed frequency used in general applications (also called “beep sounds”), but not to variable frequency or melodic sounds. It does not specify fire or gas leak alarm sounds or crime prevention alarm sounds (determined by other laws and regulations), electronic chim

27、es, voice guides or other sounds particular to communication instruments such as telephones; nor is it applicable to auditory danger signals for public or work areas (covered in ISO 7731, ISO 8201, and ISO 11429). It is not applicable to machines and equipment used for professional work; nor does it

28、 specify the sound pressure levels of auditory signals from the consumer products. NOTE For the determination of these levels, taking into consideration accessible design, see ISO 24501. 2 Normative references The following referenced documents are indispensable for the application of this document.

29、 For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60050-801, International electrotechnical vocabulary Chapter 801: Acoustic and electroacoustics 3 Terms and definitions For the purpose

30、s of this document, the terms and definitions given in IEC 60050-801 and the following apply. 3.1 auditory signal sound emitted from a product for the purpose of conveying information to help the user to use the product correctly 3.2 operation action which the user performs, using a product for achi

31、eving a purpose DIN EN ISO 24500:2011-02 EN ISO 24500:2010 (E) 5 3.3 operation confirmation signal sound acknowledging the response of a product immediately after a users action to operate it NOTE Operation confirmation signals include reception and start signals, stop signals and starting position

32、signals. 3.3.1 reception and start signal auditory signal acknowledging receipt of a users action to start or operate the product 3.3.2 stop signal auditory signal acknowledging the users action to stop the operation of the product 3.3.3 starting position signal auditory signal announcing the refere

33、nce or starting position for the case in which the user makes a menu selection by repeatedly pushing a button 3.4 end signal sound announcing the completion of a product action 3.5 caution signal sound announcing that the product cannot function independently in normal operation (or state) NOTE 1 Ca

34、ution signals differ in purpose from auditory emergency signals and auditory warning signals. The latter two signals are used to notify people of a serious dangerous situation in public and work areas and are defined in ISO 7731. NOTE 2 The caution signal is classified into weak and strong caution s

35、ignals according to the degree of importance of the information. 3.5.1 weak caution signal auditory signal which attracts the attention of the user to operation mistakes and requests the users resetting of the product or assisting in the operation EXAMPLE An auditory signal of a washing machine anno

36、uncing that the lid is open. 3.5.2 strong caution signal auditory signal announcing the necessity of interrupting operation of the product and the user intervening to correct some abnormality before continuation of operation EXAMPLE An auditory signal of an electric oven announcing that it has stopp

37、ed heating because of overheating. 3.6 ON time time during which the signal continues to sound 3.7 OFF time time without sounding a signal 3.8 ON/OFF pattern sequence of ON times and OFF times that constitute a signal DIN EN ISO 24500:2011-02 EN ISO 24500:2010 (E) 6 4 General aspects of auditory sig

38、nals for products 4.1 User control of volume level The user should be able to adjust the volume level of auditory signals based on hearing ability, distance from the product, effects of ambient environmental sounds, etc. NOTE ISO 24501 describes detailed methods for setting and adjusting the sound p

39、ressure level of auditory signals in noise. 4.2 Repetition of caution signals Caution signals shall be repeated only as long as the cause of signalling exists. 4.3 Fundamental frequency of auditory signals The fundamental frequency of auditory signals should not be higher than 2,5 kHz. NOTE 1 The de

40、finition of “fundamental frequency” is given in IEC 60050-801. NOTE 2 Many older users with age-related hearing loss have difficulty hearing high-frequency tones. NOTE 3 Audibility of signals depends not only on their frequency, but also on their sound pressure level. ISO 24501 gives detailed method

41、s for setting and adjusting the sound pressure level of auditory signals. 4.4 Options for signal frequencies Products should provide several options for signal frequencies so that users with hearing impairments can select an audible signal. 4.5 Use of complex sound signals Products should provide a

42、complex sound signal (i.e. a signal with several harmonics, containing more than one frequency component). NOTE 1 The definition of “complex sound” is given in IEC 60050-801. NOTE 2 Complex sound signals are more likely to be heard than pure-tone-like signals by people with impaired hearing at some

43、frequencies. 4.6 Turning off auditory signals Except for caution signals, the user should be provided with a means to turn off auditory signals. 5 Temporal patterns of auditory signals 5.1 General Auditory signals are more abstract than spoken instructions. For this reason, temporal patterns of audi

44、tory signals should be designed so as to be understood without giving further instruction to the user, and not to be confused with other auditory signals used by the same product or those of another product used at the same time and place. DIN EN ISO 24500:2011-02 EN ISO 24500:2010 (E) 7 The tempora

45、l patterns of auditory signals presented in 5.2 to 5.4 shall be used for each signal category. NOTE A temporal pattern is a robust cue by means of which the user discriminates auditory signals from one another; it can therefore be used more effectively than other acoustic characteristics such as fre

46、quency or timbre. 5.2 Operation confirmation signals ON/OFF patterns in accordance with Table 1 shall be used for operation confirmation signals. Table 1 ON/OFF patterns of operation confirmation signals ON time OFF time Signal category s s Repetition Onomatopoeic description Pattern Reception and s

48、ignals may be used in a product if necessary. The patterns are presented in an arbitrary order, and any signal may be chosen from a signal category, as appropriate.
