Abstract
Disclosed is a method for modifying the frequency response of a wooden article by exciting the article with acoustic energy. Frequency response is the measure of a system's spectrum response at the output due to a signal of varying frequency (but constant amplitude) at its input. The acoustic energy includes at least one excitation frequency, a composite broadband frequency component, or a combination thereof, which is preferably in the audible spectrum (20 to 20,000 Hz). The use of acoustic energy from the remote source provides non-contact excitation of the wooden article. In one embodiment, the acoustic energy is at least one sound wave which comprises at least one resonant frequency of the wooden article, at least one acoustic mode of the wooden article, at least one discrete frequency, a broadband frequency component, or any combination thereof.
