What is sound-absorbing sponge?


1. Sound-absorbing sponge. The most common indoor soundproofing material is sound-absorbing sponge, which is suitable for noisy places such as ktv karaoke halls, recording studios, dance halls, and theaters. It is also moisture-proof and waterproof, but the sound-absorbing sponge also has its shortcomings, and its flame retardancy is not good.


2. Wave crest sound-absorbing sponge. It is a kind of sponge that has been specially processed by the equipment to form a concave-convex wave shape. It is filled with small voids and semi-open structure, which can absorb a large amount of injected sound wave energy and attenuate the sound wave.
