人类工效学.无障碍设计.消费品用听觉信号

[中文适用范围]： 本国际标准规定了在有或没有视力或听力障碍的人使用消费品时，用作反馈其操作或状况的听觉信号。本标准旨在根据产品类型及其使用条件适当地应用于此类产品。本标准适用于一般应用中使用的固定频率听觉信号（也称为“蜂鸣声”），但不适用于变频或旋律声音。本标准未规定火灾或煤气泄漏警报声或预防犯罪警报声（由其他法律法规确定）、电子铃声、语音指南或电话等通讯工具特有的其他声音；本标准也不适用于公共或工作区域的听觉危险信号（涵盖在 ISO 7731、ISO 8201 和 ISO 11429 中）。本标准不适用于用于专业工作的机器和设备；本标准也没有规定消费品听觉信号的声压级。注：要确定这些级别，并考虑到无障碍设计，请参见 ISO 24501。 [外文原描述]： ISO 24500:2010 specifies 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 applicable 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 chimes, 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 specify the sound pressure levels of auditory signals from the consumer products (for the determination of these levels, taking into consideration accessible design, see ISO 24501).
