dcterms:description
Many researchers have tried to characterise the sound quality of violins by objective quality parameters. An experimental method described here is very similar to the technique of violin playing termed %22pizzicato%22. A violin is placed horizontally on two supports with its string down. Small mass hangs from its string in a standard playing position. After releasing, the transient response is picked up by a Brüel&Kjar 4374 accelerometer placed on the back plate opposite to the bridge. For the first set of measurements a measuring card ADSP2115 was used for recording signals; for the second set of measurement's a Brüel&Kjar 2825 PULSE. A number of tests proved the reproducibility of excitation end measurement. Several violins of different quality were measured. Data were processed in a system MATLAB. STFT and Wavelet Transform were used for calculation of frequency spectrum and wavelet map. Characteristics which could be important for a tonal quality of a violin have also been noted.
