This Standard specifies methods for determining the sound pressure level range of auditory signals so that the users of consumer products, including people with agerelated hearing loss, can hear the signal properly in the presence of interfering sounds.
Auditory signals, in this Standard, refer to sounds with a fixed frequency (also called beep sounds) and do not include variable frequency sounds, melodic sounds, or voice guides.
This Standard is applicable to auditory signals which are heard in the room 1) at an approximate maximum distance of 4 m from the product, as long as no physical barrier exists between the product and the user. It is not applicable to auditory signals heard through a head receiver or earphones, or to those heard with the ear located very near to the sound source because of the interference of the head with sound propagation.
This Standard does not specify the sound pressure level of auditory signals regulated by other statutes, such as those for fire alarms, gas leakages and crime prevention, nor does it specify auditory signals particular to a communication tool such as telephones.
This Standard does not specify auditory danger signals for public or work areas which are covered in ISO 7731, ISO 8201, and ISO 11429.
Note 1) For auditory signals which are heard at a distance exceeding 4 m between the product and the user, or in the presence of a wall between the two, higher sound pressure level than those specified in this Standard may be needed.
NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 24501: 2010 Ergonomics-Accessibl
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
