Abstract

This paper describes new experimental results on equal-loudness level contours and the minimum audible sound field (MAF) as well as a supplementary consideration on experimental procedures. Our equal-loudness level contours for 20 phon or greater are close to those obtained by Fletcher and Munson rather than to those by Robinson and Dadson. On the other hand, the minimum audible sound field reported herein is similar to that in ISO 226 which was obtained by Robinson and Dadson. Supplementary experiments to clarify the discrepancies among various research studies suggested that the experimental condition, e.g., whether the level of the standard tone or the level of the test tone is varied, could be a possible cause to explain a part of the discrepancies.
