Equal-loudness-level contours for pure tones.
Equal-loudness-level contours provide the foundation for theoretical and practical analyses of intensity-frequency characteristics of auditory systems. Since 1956 equal-loudness-level contours based on the free-field measurements of Robinson and Dadson [Br. J. Appl. Phys. 7, 166-181 (1956)] have been widely accepted. However, in 1987 some questions about the general applicability of these conto...
متن کاملObtaining equal loudness contours from Weber fractions
An empirical equation from Riesz's classic study on difference thresholds is treated in a new manner. Reformulating the expression for the Weber fraction allows one to account for the shape of the loudness function at different frequencies. Furthermore, the emerging loudness function unifies both the commonly used power and logarithmic laws of sensation. In principle, equal loudness contours ca...
متن کاملEqual-loudness Contours at High Frequencies
Interfrequency loudness matches were obtained for 12 pairs of frequencies from 1 to 16 kHz over a range of sensation levels (SL) from 4-to-100 dB. At 10 kHz and below, a linear matching function with a slope of 1.0 provides a good account of the data. In contrast, loudness-matching functions at higher frequencies are curvilinear in shape. Moreover, the regional slope values are both level and f...
متن کاملSpeech Logarithm Filtering Equal − Loudness Curve Power −
Most speech parameter estimation techniques are easily innuenced by the frequency response of the communication channel. We have developed a technique that is more robust to such steady-state spectral factors in speech. The approach is conceptually simple and computationally eecient. The new method is described, and experimental results are reported, showing a signiicant advantage for the propo...
متن کاملPrecise and Full-range Determination of Two-dimensional Equal Loudness Contours
The equal-loudness contours describe the frequency characteristic of sensitivity of our auditory system. A set of the equal-loudness contours based on British data measured in mid-1950 was standardized as ISO 226. However, several research results reported in mid-1980 showed that the set of equal-loudness contours in ISO 226 contained a large error. We, therefore, carried out this project to de...
