Sound Insulation Inversion to an Attached Room in Buildings

Article Preview

Abstract:

With respect to the higher sound insulation need of the buildings, the attached room may be considered to adopt. A calculation model is applied to predict the sound insulation of a specified attached room. Realistic sound insulation inversion, furthermore, is consistent with the procedure of engineering practice. By the artificial immune algorithm (AIA), the inverse sound insulation prediction model is developed, which adjust the insulation of each element (wall, door and window etc.) and sound absorption of the attached room. Under agreeing with the reasonable configuration of an attached building and meeting sound insulation requirement simultaneously, it was found that acoustic properties of each member within a whole attached room were obtained. As a consequence, the material and even the configuration of each wall can also be determined. It will be beneficial to building design.
