Call Centers have worked hard to acoustic problems, continuous product development, material research done. But 6 of about 22 products identified and have achieved an acceptable sound absorption coefficients. With these products, MODPRO ® sound absorption coefficient of 0:45 (almost 50%) have achieved. A step further in this regard was not enough for the utility model patent and trademark have MODPRO ®.

  Sound insulation systems are produced in a structure different from known MODPRO ®. Insulators with the layered structure of a simple audio tone swallows more than doubled. Different places can be created with an unusual decorative appearance. Design will process the practical application of the other products as well as MOD, extensible and portable structure, a versatile, high-efficiency product.
