PU egg foam-Sound Absorption
Specifications:
Polyurethane egg crate foam, also known as egg tray foam or peak sound-absorption foam, is a high-performance acoustic material made from polyurethane foam as the base substrate. It features a unique undulating wave-like surface design (similar to an egg crate structure). This three-dimensional structure effectively absorbs and disperses sound wave energy, significantly reducing noise and minimizing echo interference, thereby improving sound purity.
This product is widely used in architectural acoustics, industrial noise reduction, and professional audio fields, making it an ideal sound absorption solution for recording studios, audio-visual rooms, industrial equipment rooms, and commercial spaces.
