Five kinds of loudness functions were examined to determine a suitable function for drawing equal-loudness-level contours based on experimental data. First, equal-loudness relations were measured between 125-Hz and 1-kHz pure tones from 70 phons down

The current international standard of the equal‐loudness level contours specified in ISO 226 is found to involve large errors, epecially for frequencies below 1 kHz. In the past 10 years, a series of experiments has been conducted for full revision

Some experiments on the loudness of impact sound were carried out, where the modelimpact sounds based on the actual ones were used as test stimuli. From these experiments, it is clarified that the reading of the sound pressure level through a circuit

The loudness of impact sounds with wide-band spectrum was investigated, and compared with that of the impact sound with tonal character. The stimuli used in this experiment were synthesized by amplitude modulation of pink noise or white noise. As the

This paper reports and discusses the results of the second stage of experiments of a round robin test on the evaluation of impact sounds. Two psychological attributes, loudness and noisiness, were dealt with in this study. The PSE's for both attribut

The purpose of the study is to investigate the loudness of impact sounds we often encounter in our daily life. About thirty samples were collected first, and then analyzed in prior to laboratory experiments. By taking the results of those analyses in

This paper reports and discusses the results of a round robin test in Japan for the loudness of impact sound, which aims to establish how to evaluate the loudness, the noisiness and the annoyance of impact sounds and to describe them. As impact sound
