Database of domestic sounds for evaluation of auditory-signal audibility: JIS/TR S 0001

Abstract

A new Technical Report of Japanese Industrial Standard, JIS/TR S 0001, was made public in January 2002. This JIS/TR is a database for determining the acoustic properties of auditory signals used in consumer products; it consists of (1) graphical data of the frequency characteristics of domestic sounds, and (2) a library of recorded sounds on compact disc. The former can be used to graphically determine combinations of frequency and sound pressure level of auditory signals that are audible against domestic sounds. The latter is intended for use in a psychoacoustic experiment in which auditory signals are presented along with domestic sound(s) of the library; listeners are asked then to judge how they perceive the signals. The experiment can be carried out using either a loudspeaker or headphones. This JIS/TR will facilitate the development of suitable auditory signals for domestic appliances used under various noisy conditions and by a variety of users, including the elderly.
