Foreword
This translation has been made based on the original Japanese Industrial
Standard established by the Minister of Economy, Trade and Industry
through deliberations at the Japanese Industrial Standards Committee
according to the proposal of establishing a Japanese Industrial Standard
from National Institute of Advanced Industrial Science and Technology
(AIST)/National Institute of Technology and Evaluation, Conformity
Assessment Center (NITE), with a draft of Industrial Standard based
on the provision of Article 12 Clause 1 of the Industrial Standardization
Law.
Attention is drawn to the possibility that some parts of this Standard
may contlict with a patent right, application for a patent after opening
to the public, utility model right or application for registration of utility
model after opening to the public which have technical properties. The
relevant Minister and the ~Japanese Industrial Standards Committee
are not responsible for identi(ying the patent right, application for a
patent after opening to the public, utility model right or application for
registration of utility model after opening to the public which have the
said technical properties.

JAPANESE INDUSTRIAL STANDARD JIS S 0014 : 2003
Guidelines for the elderly and
people with disabilities-Auditory signals
on consumer products-Sound pressure
levels of signals for the elderly
and in noisy condition
Introduction At present consumers live their life surrounded by various consumer
products such as electrical and electronic appliances, information and telecommuni
cation devices, office automation equipment, gas or cooking and heating appliances,
toys, sanitary accommodations, and health appliances which use auditory signals. These
auditory signals may be indistinct due to a user's hypacusis which develops with ag
ing or jamming sounds. This Japanese Industrial Standard is issued as guidelines
(recommendations) when designing auditory signals which product users including
the elderly with hypacusis can hear properly in consideration of the presence of jam
ming sounds. When using this Standard, a specified item can be selected suitably for
the kind of product or other conditions. Furthermore, this Standard precludes the
equipment for special use such as use for facilities, business use and professional use.
1 Scope This Standard specifies the guidelines (recommendations) for designing
the range of sound pressure levels of auditory signals which the users of consumer
products, especially visually impaired persons, the elderly with a visual impairment
and hypacusis which develops with aging can hear properly in consideration of the
presence of jan1ming sounds. However, auditory signals regulated by other statutes
such as signals for fire alarms, signals for gas leakages, signals for crime prevention,
and auditory signals of an electronic chime and a voice guide, and auditory signals
peculiar to a communication tool such as telephones are excluded.
Remarks 1 "Auditory signals", in this Standard, refer to the sound heard in the
same room as that where the product is used or in the next room
not shut off by walls.
2 "Auditory signals", in this Standard, refer to the auditory signal gen
erally used of which the frequency is constant (also called a beep
sound).
3 This Standard should apply even when using a frequency changing
sound, a melody, etc.
4 Auditory signals heard through a head receiver or an earphone, and
auditory signals heard with the ear being located near the sound
source are excluded.
2 Normative references The following standards contain provisions which, through
reference in this Standard, constitute provisions of this Standard. The most recent
editions of the standards (including amendments) shall be applied.

3 Definitions For the purposes of this Standard the definitions shall be in accor
t
dance with JIS S 0013 and JIS Z 8106, and the following definitions shall apply:
a) jamming sound A product actuation sound or a living environment sound which
is likely to have the biggest effect on listening comprehension of auditory sig
nals to be designed.
b) product actuation sound A sound generated by actuation of a consumer prod
uct incorporating auditory signals to be designed.
c) living environment sound A sound generated in the room where a consumer
product incorporating auditory signals to be designed is used, or, in the next room
not shut off by walls, etc. This includes a sound generated by the behavior of a
consumer (for example, the sound of water generated when washing the dishes
in a kitchen), or an actuation sound of a product other than that incorporating
auditory signals to be designed (for example, the actuation sound of a cleaner).
d) background noise All sounds other than the sound to be measured (audi
tory signals or jamming sounds) at a measurement location.
Remarks: The sound not to be measured as jamming sound among living en
vironment sounds shall be background noise.
4 Symbols The symbols used in this Standard shall be as follows:
a) Ls,A: A-weighted sound pressure level of auditory signals (dB)
b) LN,A: A-weighted sound pressure level of jamming sound (dB)
c) Ls•oct: Level of frequency band which has the maximum value among octave
band pressure levels of auditory signals (dB)
d) LN, oct: Octave-band pressure level (dB) of jamming sound at the same frequency
band as Ls, oct
e) Ls, 1/3 oct: Level of frequency band which has the maximum value among third
octave-band pressure levels of auditory signals (dB)
f) LN, 1/3 oct: Third-octave-band pressure level (dB) of jamming sound at the same
frequency band as Ls, 1/3 oct
5 Measuring method of sound pressure level of auditory signals
5.1 Measuring device The measuring device shall be as follows:
PROTECTED BY COPYRIGHT

S 0014: 2003
a) For measurement, use a sound level meter specified in JIS C 1502, or a preci
sion sound level nleter specified in JIS C 1505 (hereafter referred to as "level
meters").
b) For performing octave-band analysis and third-octave-band analysis, use an ana
lyzer specified in JIS C 1513.
5.2 Measurement location The measurement location shall be as follows:
a) Perform the measurement in the room where the reflection of the face other
than that on which a product is installed is as small as possible.
b) Install a product on a table or a floor as robust as possible.
Remarks 1 When there is an installation method peculiar to a product, such
as hanging on a wall, etc., install according to the method.
2 In the case where the product used as hand-held or a remote con
trol device incorporating the sounding source is to be measured,
the product may be supported with a suitable holder instead of being
placed on the plane.
c) When measuring according to the method specified in 5.4 a) or 5.4 b), the back
ground noise shall be lower than the sound pressure level of the auditory sig
nal measured according to the method by not less than 10 dB.
5.3 Position of measurement point The position of the measurement point shall
be as follows:
a) Place a microphone towards the control unit of a product at the position which
corresponds to the head centre of a user when the user of the product is reach
ing for it to operate it. The distance between the microphone and the control
unit of the product at this time shall be 500 mm.
b) The position of measurement point shall be determined as shown in Fig. 1 ac
cording to the respective cases, such as, the case where the control unit is lo
cated at the front side of the product, where the contI'ol unit is located at the
upper part of product and where the control unit of product or the remote con
trol device is located on the wall, etc. However , when the position of measure
ment point shown in Fig. 1 differs largely from the head centre of the user at
the time of operation of the product due to the construction of the product, a
suitable position other than that shown in Fig. 1 may be determined as the mea
surement point.
