[Better Sound Absorption] The acoustic panels feature a pyramid structure, creating multiple sound diffusion channels. With a thickness of 2 inches, the acoustic foam effectively absorbs and dissipates sound energy, helping to reduce reverb, flutter echoes, acoustic reflections, and unwanted noise. [100% Polyurethane, SGS Safety Certified] Made from 100% polyurethane without added fillers, these acoustic panels ensure consistent quality and performance. The foam has passed SGS safety testing, confirming it is non-toxic and safe for use in home and professional environments. [Multi-Use Application] Suitable for small to medium-sized rooms, these panels are ideal for use in home theaters, recording studios, offices, and places of worship, where they help minimize noise and improve sound clarity. [Fire Safety Compliance] The acoustic foam meets U.S. fire safety standards. It is flame resistant and will self-extinguish upon removal of ignition source, forming a protective char layer to help prevent flame spread.
