Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction
When the persons with seeing impairment and blindness walk and travel independently, the auditory
guiding signals in public facilities for mobility assistance are very beneficial for them to know the
location (i.e. direction and distance).
This International Standard provides the guidelines of sound characteristics and specifications of
sound equipment of the auditory guiding signals in public facilities for mobility assistance of mainly the
persons with seeing impairment and blindness. The provided sound characteristics and specifications
of sound equipment enable the user to detect the sound location correctly even in the noisy environment.
This International Standard is useful for the sound designers who design the auditory guiding signals
in public facilities, and the designers who plan the public facilities.

INTERNATIONAL STANDARD ISO 19029:2016(E)
Accessible design — Auditory guiding signals in public
facilities
1 Scope
This International Standard 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 pers
