Simple model of a piano soundboard
Nicholas J. Giordano · The Journal of the Acoustical Society of America · 1997
The vibrational properties of a simple finite-element model of a piano soundboard are considered. The main focus is on the behavior of the mechanical impedance in the musically important frequency range ∼50–104 Hz. The model includes the effects of elastic anisotropy and the ribs. It is argued that the ribs are an essential ingredient for producing the behavior of the impedance which is observed experimentally.
