Sound Insulation

Is the ability of building elements or structures to reduce sound transmission To compare sound insulation properties you need to take into account the area of the dividing partition/wall, as well as the volume and sound absorption properties of the receiving room. To do this, measurements are Normalized to a Reference…

Sound insulation

The capacity of a structure to prevent sound from reaching a receiving location. Sound energy is not necessarily absorbed; impedance mismatch, or reflection back toward the source, is often the principal mechanism.

Classe de Transmissão de Som (STC: sound transmission class)

Valor obtido através da classificação dos valores medidos de perda de transmissão de som de acordo com a norma ASTM E 413, “Classification for Sound Rating Insulations”. Fornece uma indicação rápida do desempenho de uma divisão relativamente a certos problemas comuns de isolamento sonoro. Para determinar a classe de tr…
