Piercing sound-absorbing board sound-absorbing principle is the helmholtz resonance sound absorption principle.
Is the use of the special structure of material, let the incident acoustic oscillations in the big piece at the end of the cavity, the sound waves with partition and the cavity bottom collision, and collision between acoustic, sound energy consumption, thus until the effect of sound absorption.
The structural sound-absorbing characteristics of piercing sound-absorbing board, similar to the warm water bottle sound-absorbing principle in our life.
