Piano tones have partials whose frequencies are sharp relative to harmonic values. A listening test was conducted to determine the effect of inharmonicity on pitch for piano tones in the lowest three octaves of a piano. Nine real tones from the lowest three octaves of a piano were analyzed to obtain frequencies, relative amplitudes, and decay rates of their partials. Synthetic inharmonic tones ...

We analyzed the prosodic features of “anger,” “joy,” and “sadness” expressions in Noh farce (“Kyohgen”) speech depending on the degree of the emotions. The degrees were divided into the following four categories: “neutral,” “low,” “medium” and “high.” A male Noh comedian uttered 6 words that are phonetically similar with one another five times, and the parameters of the prosodic features in the...

measurement of magnitude and frequency of the voltage flicker is very important for monitoring andcontrolling voltage flicker efficiently to improve the network power quality. this paper presents twonew methods for measurement of flicker signal parameters using shuffled frog leaping algorithm(sfla) and imperialist competitive algorithm (ica). this paper estimates fundamental voltage andflicker ...
