“…Sound absorption capabilities of porous zeolite with macropores -which is a ceramic material fabricated by high-temperature sintering -were recently investigated by Cuiyun et al (2012). They measured acoustic absorption coefficient in the frequency range from 200 Hz to 4 kHz for 8 ceramic samples with various porosity, bulk density, flow resistivity, and thickness.…”

Recently, a new class of ceramic foams with porosity levels up to 90% has been developed as a result of the association of the gelcasting process and aeration of the ceramic suspension. This paper presents and discusses original results advertising sound absorbing capabilities of such foams. The authors manufactured three types of alumina foams in order to investigate three porosity levels, namely: 72, 88, and 90%. The microstructure of foams was examined and typical dimensions and average sizes of cells (pores) and cell-linking windows were found for each porosity case. Then, the acoustic absorption coefficient was measured in a wide frequency range for several samples of various thickness cut out from the foams. The results were discussed and compared with the acoustic absorption of typical polyurethane foams proving that the alumina foams with high porosity of 88-90% have excellent sound absorbing properties competitive with the quality of sound absorbing PU foams of higher porosity.

“…Despite the fact that passive measures, such as wall cladding panels with porous materials and resonators, address only the consequences but not the main causes of noise, these factors are often the only possible and viable solution. e ability of building materials to absorb sound waves typically depends on their sti ness, density, and porosity [5][6][7]. e function of the absorption coe cient exists in order to quantify the ability of materials to absorb sound waves at a speci c frequency.…”

Noise attenuation is a key contemporary issue associated with the protection of human health. In this study, the possibilities of affecting acoustic properties of plaster composites by the addition of short-fibre reinforcement are described. e improvement of attenuation abilities was first verified using a simple numerical model with a pure plaster followed by using a reinforced plaster.e model results revealed a mutual correlation between the fibre ratio and dissipated acoustic energy. Hence, typical plasters used in the building industry (e.g., plaster, lime cement, and cement) are used as the base materials of the tested composites. e reinforcing dispersion in the form of short fibres (basalt and glass) with a defined length was selected after evidence from previously reported studies and after the comparison of some other fibres with respect to the trade-off between the rendered mechanical properties and cost. Transfer functions of the tested samples were measured using an impedance tube with two microphones, followed by the calculation of the total acoustic absorption. On the other hand, cement and plaster materials exhibited a low damping ability, and the absorption could be considerably increased by the addition of fibres, especially in the area around 1 kHz. In contrast, the UM plaster exhibited good damping properties even without the dispersion, and the addition of improper fibres such as glass ones possibly worsened the properties. e acoustic attenuation of the plaster composites can be improved by the appropriate combination of the base material and fibre dispersion. However, it is not possible to generalise this improvement for all possible combinations.
