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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 15006 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 13, Ergonomics
applicable to road vehicles.
This second edition cancels and replaces the first edition (ISO 15006:2004), which has been technically revised.

Introduction
The driver and the vehicle are an integrated system that includes the environment, the primary vehicle controls,
the instrumentation, and the transport information and control systems (TICS). The driving task, and human
capabilities and limitations, are other primary factors. TICS are intended to support the driver’s primary task,
and therefore it is expected that the overall workload of the driver will not be negatively influenced, while
performance and comfort should be increased.
The multitude of information to be displayed to the driver through TICS may create the need to minimize visual
load and make more and better use of the auditory channel. This International Standard provides ergonomic
specifications for the design and installation of auditory displays presenting speech and tonal information while
driving. The aim of these specifications is to help designers to provide auditory signals which meet usability,
comfort and safety criteria.

INTERNATIONAL STANDARD ISO 15006:2011(E)
Road vehicles — Ergonomic aspects of transport information
and control systems — Specifications for in-vehicle auditory
presentation
1 Scope
This International Standard establishes ergonomic specifications for the presentation of auditory information
related to transport information and control systems (TICS) through speech or sounds. It applies primarily to
the use of auditory displays to the driver when the vehicle is in motion, but it may also be applied when the
vehicle is stationary. It presents a set of requirements and recommendations for in-vehicle auditory signals
from TICS, and provides characteristics and functional factors for maximizing auditory signal intelligibility and
utility while helping prevent auditory or mental overload.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
ambient auditory noise
auditory sensory stimulus bearing no informational relationship to the presence or completion on the immediate task
that surrounds the driver in the vehicle’s environment, including sound emanating from inside and outside the vehicle
3.2
audibility
degree to which an auditory signal can be heard by a person with normal hearing
3.3
auditory icon
auditory signal that represents an event or action
NOTE This auditory signal can be a synthesized sound that gives the impression of specific event or a recorded
sound from everyday life.
3.4
auditory signal
tone or verbal cues emitted by an in-vehicle device, which provide information to the driver or passengers
1) The German standard DIN 45631 is largely identical to ISO 532. In practice, references for calculating loudness
[8]
according to ISO 532 usually implement the code given in DIN 45631 .

3.5
broadband signal
complex sound whose acoustical energy is distributed over a wide range of frequencies
3.6
comprehensibility
characteristic of an auditory signal that enables the driver to understand its meaning in the context in which
it is provided
3.7
diffuse field
sound field in which the sound pressure level is the same everywhere and the flow of energy is equally probable
in all directions
3.8
distinguishability
characteristic of an auditory signal enabling the driver to perceive the differences between it and other audible
signals within the driving environment
NOTE Other audible signals include warning signals and signal noise, but exclude ambient noise.
3.9
free field
sound field with no reflective surfaces over the frequency range of interest
3.10
loudness
sensation (perception) that is most closely related to the sound amplitude of an acoustical stimulus
NOTE In this International Standard, loudness is expressed in units of sones.
3.11
main audible component
tonal component with the most energy in the auditory signal
3.12
narrowband signal
sound whose acoustical energy is distributed over a narrow range of frequencies
3.13
narrowband spectrum
spectrum with a frequency resolution of 10 Hz or less
3.14
safety criticality
severity of the likely event that can occur if the driver is unable to avoid a specific hazard
NOTE Four levels of criticality, based on occupant (or other road user) injury and vehicle damage, are defined by
ISO/TS 16951.
3.15
safety warning
auditory signal that is intended to prevent or mitigate injuries or vehicle damage
NOTE Navigation and route guidance instructions are not safety warnings even though they might also require the
driver to take an action within a short time period.
3.16
signal-to-noise ratio
SNR
ratio of signal specific loudness spectrum to noise specific loudness spectrum

3.17
sone
subjective unit of loudness, as perceived by a person with normal hearing, equal to the loudness of a 1 000 Hz
pure tone presented frontally with a sound pressure level of 40 dB, re 20 µPa.
NOTE 1 When measured in a free field, this definition for sone is sometimes designated as sone GF. For a diffuse
(rather than free) field, the designation is sone GD. A vehicle interior may be characterized as free field or diffuse field
depending on the location (e.g. instrument cluster, audio system speakers, turbulent noise on the windshield) and type of
sound (e.g. chime, road noise, and wind noise).
NOTE 2 The loudness of a sound that is judged by a listener to be n times that of a 1-sone tone is n sones.
3.18
sound pressure level
SPL
local pressure deviation from the ambient pressure caused by a sound
3.19
specific loudness spectrum
distribution of loudness over the frequency axis
3.20
time-critical signal
auditory signal that requires a driver response to an imminent event measurable within a limited number of seconds
NOTE The signal may or may not pertain to a warning event.
3.21
tonal signal
simple sound or mixture of simple sounds with fixed frequency content
NOTE 1 A simple sound is a sinusoidal signal with fixed or single frequency content.
NOTE 2 A tonal signal can be a continuous sound or intermittent sound.
3.22
unit of information
individual or group of auditory signals regarded as a structural or functional constituent of a message
4 Signal specifications
4.1 Spectrum
4.1.1 General
The recommended frequency range for in-vehicle auditory signals is 200 Hz to 8 000 Hz.
4.1.2 Tonal signals
For tonal signals, the main audible component should lie between 400 Hz and 2 000 Hz to protect against
[22]
decreased audibility due to age-related hearing loss .
A broadband signal or a mix of narrowband signals with distinctly separated centre frequencies should be used
to improve the signal location detection and driver attention direction.
EXAMPLE A mix of two narrowband signals, with the main audible component centred around 800 Hz, and the other
component centred around 3 000 Hz.
The urgency of a situation should be reflected by the character of the signal.

4.2 Signal levels
4.2.1 General
The selection of optimal sound amplitude is a matter of balancing listener comfort against signal audibility. The
latter is primarily a function of the signal-to-noise ratio (SNR) between the auditory signal and the ambient
auditory noise. It should be kept in mind that loudness depends on the level of the ambient auditory noise and
on the level of the auditory signal within a given frequency band. Therefore, loudness at a given SNR increases
with rising ambient auditory noise.
4.2.2 Measuring sound loudness
The method for measuring and evaluating the loudness of auditory signals shall be as described in Annex A.
[7]
Specific details of the method are given in DIN 45631 .
