Timber Slat Acoustic Panel Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)

Parallel timber slats (solid or MDF) with gaps, backed by acoustic felt or mineral wool. The slats resonate at specific frequencies and sound passes through gaps to the absorber. Combines design aesthetics with mid-range absorption.
