The Acoustic Cavity Helmholtz Resonator (A0 Peak near 275 Hz)
Air inside the soundbox acts as an acoustic spring while air plugs inside the f-holes act as oscillating masses, boosting low notes.
F-Hole Perimeter vs Area Conductance Kinetics
Elongated, fluted f-holes dramatically increase perimeter length, yielding higher air flow velocity than circular holes of equal area.
Soundpost Positioning and Plate Decoupling
The spruce soundpost wedges beneath the treble bridge foot, transforming bridge lateral rocking into vertical pumping of the back plate.
