Acoustic Bubble & Droplet Model

Andy Farnell, Designing Sound (Ch 34: Water) & Marcel Minnaert's Cavity Equation

Tap or Click to Drop Dispatches instantaneous discrete droplet event (triggerBubble)

Physical Acoustic Parameters

Radius (Size) 4.0 mm

Depth 10 cm

Viscosity 0.35

Continuous Rate 0 drops/s

Volume 0.70

Acoustics Note: Natural bubble pitch is governed by Minnaert resonance: f₀ ≈ 3.26 / r (Hz). As the cavity forms and detaches, hydrostatic relaxation induces an authentic upward chirp f(t) = f₀(1 + αt) with viscous damping exp(-ηt).
