AB  - Porous materials are frequently used in sound insulation applications. In building acoustics they are installed inside the separating constructions to absorb unwanted mid and high frequencies propagating through them. Although it is not required by UK Building Regulations, low frequency noise transferred through separating partitions is considered as a nuisance by occupants and could and should be addressed. A laboratory study had been conducted to investigate the effect of various types of porous materials that may be used for partition fillings on the sound absorption over low and mid frequencies. The results suggest that open pore materials could improve low frequency range of absorption while have no detrimental effect on mid frequency absorption level.
