Sound absorbing principle:
The sound-absorbing sponge is filled with fine voids and semi-open structures, which absorb more sound waves that come in, demonstrate the attenuation effect of sound attenuation, reducing interference and reverberation of sound emitted indoors and preserves the sound purity. The higher the density of the sponge, the better the sound absorption and sound insulation. Sound-absorbing sponge is primarily used for soundproofing and soundproofing indoors and if you want to reduce outside noise, depending on the volume and nature of the sound source, it may not provide sufficient sound insulation effect.
Flame Retardant Description:
Flame retardant means you can remove the hidden danger of the flame and will automatically disappear in about 3 seconds from the open flame. If you cannot control the source of the fire, it will continue to burn and will not completely prevent burning. Please acknowledge
