  • Measuring a frequency response of a guitar
    Šali, Samo ; Kopač, Janez, 1949-
    ǂA ǂmethod for measuring a frequency response function (FRF) of a classical guitar is presented. Instead of measuring a response signal on the guitar body, which is often performed in modal analysis ... of musical instruments, a sound pressure at 1 m from the impulsively excited guitar at the bridge was recorded. Under the given circumstances the measured FRF showed a high degree of linearity between 70 - 250 Hz as well as high value of the coherence function. The first resonant peak of FRF which corresponds to a normal radiating mode showed a significant correlation with the quality of six tones: The amplitude of this peak, which is presumably related to an interaction of both resonant boards and the air between them, was significantly higher for a good guitar. For this reason, and because of its simplicity, the described method presents a good starting point for guitar tone improvement by modifications of both resonant boards with braces.
