Description
Specification: Total Size: 30 * 30 * 5cm (12″*12″*2″) Material: Polyurethane foam Color: Purple/Black Feature: Using polyurethane foam material. After special treatment device side triangular groove shape formed by the complex process of foaming silencer, sound-absorbing, sound insulation, shock absorption sponge materials. Its interior is full of small voids and semi-open pore structure can absorb a lot of energy incident on the acoustic attenuation of sound waves play a role, reducing chamber reflected sound interference and response, improve the purity of sound; noise sound-absorbing material is a high-performance product.
