Despite the fact that there are some studies on the acoustic behavior of different concrete material, it is necessary to systematize the current state of sound-insulation concrete composites and structures made of them. Lightweight porous materials absorb sound well, while heavyweight and hard materials reflect a significant portion of sound energy. Sound insulation is the sound transmission loss of the building partition. The absorption of sound in a porous material is related to the loss in energy wherein the incident noise energy converts to heat energy and some other energies due to vibration, friction, and air viscosity. Hence, there is a relationship between the incident energy and the absorbed, transmitted, or reflected energy. Usually, when a sound wave strikes or hits the surface of a building, the sound energy gets absorbed, transmitted, or reflected away. The most important step along this path is ensuring the acoustic well-being of residents through the optimal design of building envelopes. During the construction and operation of these buildings, it is necessary to ensure comfortable living conditions for people. Ĭoncrete is a widespread and cheap structural material for the construction of residential buildings of any volume and number of storeys. Sound waves reflections in a surrounded narrow thoroughfare. This literature study also provides a critical review on the type of concretes, the acoustic insulation of buildings and their components, the assessment of sound insulation of structures, as well as synopsizes the research development trends to generate comprehensive insights into the potential applications of AIC as applicable material to mitigate noise pollution for increase productivity, health, and well-being. To this end, this article reviews the noise and sound transmission in buildings, types of acoustic insulating materials, and the AIC properties. The sound absorption of acoustic insulation concrete (AIC) can be improved by forming open pores in concrete matrices by either using a porous aggregate or foam agent. It is found that the level of sound reflection in modified concrete is highly dependent on the type of aggregates, size and distribution of pores, and changes in concrete mix design constituents. Different types of concrete behave differently as a sound conductor especially dense mixtures are superior sound reflectors, and light ones are sound absorbers. In particular, this is to ensure comfortable living conditions for people in residential premises, including acoustic comfort. Concrete is the most common building material therefore, when designing structures, it is obligatory to consider all structural parameters and design characteristics such as acoustic properties.
