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.

Audibility evaluation of triangle-wave tones presented against domestic sounds: Comparison with the audibility of pure tones

“…Further details are described in [1]. Stimuli Background noises were typical sounds generated by the following electric appliances or by a person doing housework, which were adopted from a sound library [2]: (1) washing dishes at a sink and (2) a ventilation fan in the kitchen, (3) a washing machine, (4) a hair dryer, (5) running water from a shower in the bathroom, (6) a television set, and (7) a vacuum cleaner in the living room.…”

Audibility of pure tones presented against domestic sounds: Comparison of ratings between young and older adults for auditory-signal design

“…EXPERIMENT 2.1. Method Stimuli Seven domestic sounds were selected from a sound database and used as background noises [8,9]. They were typical sounds present in Japanese homes and were generated by the following electric appliances or by a person doing housework: (1) washing dishes in a kitchen sink, (2) a ventilation fan in the kitchen, (3) a clothes washing machine, (4) a hair dryer, (5) running water from a shower in a bathroom, (6) a television set, and (7) a vacuum cleaner in a living room.…”
