Abstract
A stringed instrument with a compliantly suspended sound board allows for deeper, richer sound in s smaller sized instrument. The compliant suspension of the sound board allows for greater acoustic excursions at the edges of the sound board. The resonance set up between the compliance of the sound suspension and the mass of the sound board may be placed below and near the Helmholtz resonance of the instrument to effectively create a broader, lower-frequency Helmholtz resonance than would typically be achievable in instruments of similar size.

An ASISST, comprising:
- a. A plurality of strings strung in tension;
- b. A sound board compliantly suspended from a rigid surrounding structure by a compliant suspension;
- c. Mechanical coupling between said strings and said compliantly suspended sound board.
A guitar comprising a neck, a body, strings, a ported sound board, a bridge, and a compliant suspension, said strings being coupled to said sound board through said bridge, and said compliant suspension attaching circumferentially to said sound board and coupling said sound board compliantly to said body.
