Ergonomics - Accessible design - Auditory signals for consumer products (ISO 24500:2010); German version EN ISO 24500:2010
This International Standard specifies the auditory signals used as a means to communicate information as feedback of operation or the condition of products when a user, even a person with visual impairment or an older person with impairments of vision and hearing, uses a consumer product. It does not specify fire alarm sounds, gas leak alarm sounds, or crime prevention alarm sounds, which are determined by other laws and regulations, nor does it specify electronic chimes, voice guides, and other sounds peculiar to communication instruments such as telephones. It is applicable to auditory signals of a fixed frequency used in general applications (also called beep sounds). NOTE It is also recommended that this document be used when variable frequency sounds or melodic sounds are used.*This standard specifies auditory signals used as a means of feedback via the operation or condition of products which shall be understood by users, even if they are blind or have severe visual impairments. It is applicable to auditory signals of a fixed frequency used in general applications and not to signals of a variable frequency. The target group are product designers who develop electronic and electrical objects for everyday use. By taking into account the standard it is ensured that the auditory signals of these appliances are also understood by a wide range of old and disabled people. It does not describe alarm and signal devices for fire, gas leak, or crime prevention, which are installed for legal reasons. The standard does not deal with electronic chimes, speech information systems or other communication devices, such as telephones. This standard does not deal with auditory danger signals for public or work areas which are covered by ISO 7731, ISO 8201 and ISO 11429. The Committee responsible for this standard is NA 023-00-02 GA "Gemeinschaftsarbeitsausschuss NAErg/NIA: Grundlagen zur barrierefreien Gestaltung/Accessibility" ("Joint Working Committee NAErg/NIA: Basics for barrier-free design/accessibility") at DIN.
