Abstract
Disclosed is a method for modifying the frequency response of a wood panel within an acoustical structure such as a studio or concert hall. The modification is imparted by exciting the wood paneling with acoustic energy. Frequency response is the measure of a system's spectrum response at the output to a signal of varying frequency (but constant amplitude) at its input. The acoustic energy includes at least one excitation frequency, 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 wood paneling. In one embodiment, the acoustic energy is at least one sound wave which comprises at least one resonant frequency of the wood paneling, at least one acoustic mode of the wood paneling, at least one discrete broadband frequency, a composite frequency (including multiple broadband frequencies, white noise and pink noise) or any combination thereof.
