In conclusion, our results show that, the sound radiation test, which is not affected by inter-performer variability while still being comparable to performing the instrument, can be used as an objective measurement method to determine the tone quality of the instruments. For each instrument, the correlation coefficients of the curves obtained from the two methods varied from 0,76 to 0,92 depending on the frequency range, thus it was concluded that there is a high degree of similarity. Both methods of analysis, which were tested on different types of instruments, were found to be important in determining the sound characteristics of the instruments. In order to take the hearing system’s working principles into account in the calculations, and to perform statistical analysis, 1/3 octave band correction was applied to the graphs obtained from the test results. In addition, the long-term average spectra of the sounds, which were obtained from the instruments performed in a chromatic play, were measured and the results of the two analytical methods were compared. Seven different oud, tanbur and kanun resonances were determined by the sound radiation analysis based on the impact test, which can be done without performing (playing) the instruments. Based on this analysis, sound radiation and long-term average spectrum measurements were applied to the Turkish music instruments oud, tanbur and kanun.
Abstract – In this study, the vibration and sound analysis methods, which are used to investigate the acoustic properties of stringed instruments, were investigated. BAGLAMA / SAZ (long-necked): The most commonly used string folk instrument in Turkey, the balama has seven strings divided into courses of two, two and three.
