Noise pollution has a significant impact on human health, leading to issues like hearing loss and stress. Research on developing efficient and cost-effective sound absorbing materials for vehicles, buildings, and large spaces is crucial, focusing on engineering materials solutions and tailored micro and nanostructures.Various materials and design strategies are reviewed, with a discussion on the synergistic effects of combining different constituents at different length scales for desired acoustic properties.
Noise pollution impacts the well-being of millions of people on a daily basis and can lead to serious health issues such as hearing loss and stress. Developing efficient yet cost-effective sound absorbing materials for noise reduction in vehicles, buildings and large spaces has become an important research area. The present review focuses on the latest developments in sound absorbing products based on engineering materials solutions as well as tailored micro and nanostructures. In addition, modelling techniques for simulating sound wave propagation through porous media are briefly introduced. Various materials such as polyurethane foam, thermoplastic foams, textile fabrics and composites are reviewed with different design strategies and structures ranging from foam structures to micro-perforated panels summarized and compared. The effect of different types of micro-and nanofillers, hierarchical and sandwich structures and synergistic effects of combining multiple constituents with structural designs at different length scales to achieve the desired acoustic properties are discussed. Mechanisms of each are analysed with the aim of exploring new strategies based on existing knowledge. Opportunities and obstacles are identified, while engineering applications ranging from automotive to built environment are reviewed, together with their desired properties and functions to shed light on future research directions towards advanced acoustic materials.
