Grooved Sound Absorption Panel adopts high density MDF. It can release interior noise, improve sound quality, and keep the wood decoration visal effect.
Grooved panel is composed by a lot of parallel Helmholts resonators. Changing size of narrow gap and rear cacity can control its resonance frequency. It can wider the absorptive band 2-3 times OCT by increasing porous sound absorptive material. All of Grooved panel gap size, hole diameter, hole depth are the result of accurate calculation. This is the main reason that Grooved panel has better sound absorption from 125Hz-4000Hz.
