✦ Synopsis

The changes in frequency response function (FRF) of a guitar top plate due to di!erent machining processes used to "nish the guitar tops were analyzed. The way of machining the tops had a measurable but hardly explainable e!ect on their FRF because of not well-separated frequency peaks. The additional measurements of FRF of di!erently machined square-shaped plates showed more clearly the in#uence of the machining process on the acoustic properties of a wooden board. Therefore, a general conclusion is that the machining process in#uences the acoustic properties of a wooden board. The reason for this in#uence lies in the di!erent surface shapes of di!erently machined boards.
