ISO 19029:2016规定了视觉障碍和失明者听觉引导信号的声音特征，以提供特定公共设施的位置和方向信息。公共设施包括火车站、机场、港口、公交总站、政府办公室、图书馆、社区中心、公园、学校、医院、剧院、大型超市及其厕所、楼梯等。 例如，作为一种听觉引导信号，火车站的检票口会发出一声蜂鸣声。行人，包括视力受损和失明的人，可以通过检测钟声的位置来知道检票口的位置。 注1:听觉引导信号也有助于视力正常的人。 ISO 19029:2016还规定了提供听觉引导信号的设备的设计或使用。 ISO 19029:2016未规定警报的特征，例如警报声或紧急信号。 注2:ISO 7731涵盖了听觉危险信号。 ISO 19029:2016未规定视觉障碍和失明者佩戴的个人移动设备发出的听觉引导信号的特征。

ISO 19029:2016 specifies the sound characteristics of auditory guiding signals for persons with seeing impairment and blindness to provide the location and direction information of particular public facilities. The public facilities include facilities such as railway stations, airports, ports, bus terminals, government offices, libraries, community centres, parks, schools, hospitals, theatres, large supermarkets, and its toilets, stairs, etc. EXAMPLE As an auditory guiding signal, a chime sound is emitted from the ticket gate of a railway station. Pedestrians, including persons with seeing impairment and blindness, are able to know the location of the ticket gate by detecting the location of the chime sound. NOTE 1 The auditory guiding signals are also helpful for sighted persons. ISO 19029:2016 also specifies the design or usage of the equipment that provides auditory guiding signals. ISO 19029:2016 does not specify the characteristics of the alerts, such as alarm sounds or emergency signals. NOTE 2 The auditory danger signals are covered by ISO 7731. ISO 19029:2016 does not specify the characteristics of auditory guiding signals coming from the personal mobile equipment that is worn by persons with seeing impairment and blindness.
