Sound Radiation from a Grand Piano
Besides tonal partials the sound radiated from a grand piano contains noise components arising from the excitations of the normal modes of the sound board. The radiation characteristics in the different frequency regions are shown by measured sound spectra, sound-field analysis, and recorded tone samples. For the low components up to 200 Hz, the figure-eight-shaped radiation of the sound board is determined by its vibrational dipole character.
