Helmholtz Resonator Calculator — Frequently Asked Questions
Q1 What is end correction in a Helmholtz resonator? ▾
Acoustic mass extends slightly past the physical ends of the port tube; effective length L_eff ≈ L + 0.8 × d.
Q2 How does increasing cavity volume affect resonance? ▾
Larger volume acts like a softer acoustic spring, lowering resonant frequency.
