The desired parameters and calculation methods for the acoustic insulation of roof and facade cladding materials can be determined at the design stage.
A portion of the acoustic wave striking a surface is reflected, some are absorbed, and the rest is transmitted. Reflection, absorption, and transmission rates depend on the surface's shape, the material's sound absorption coefficient, and the sound's frequency.
