| Millions of individuals experience negative effects from noise pollution , and it can cause stress and major health problems. With the development of technology, we move toward a faster and more pleasant way of life, but this has its negatives as well. Due to contemporary urbanization and industrial developments, noise occupies one of the important positions among them. Therefore, it becomes imperative to efficiently regulate noise levels across all fields. A significant field of study is now focused on creating sound-absorbing materials that are effective and affordable for noise reduction in large spaces, buildings, and vehicles. This review tries to follow the most recent advancements and potential acoustic materials, spanning from environmentally benign natural materials(NMs) to man-made structures. This analysis largely concentrates on the most recent developments in acoustic materials, such as natural fibres, recycled materials(RMs), and metamaterials. Additionally, thermoplastic foams, textile fabrics, composite materials, and micro-perforated panels are covered. While reviewing technical applications such as automobile to built environment, opportunities and barriers are discovered. All of these acoustic materials have received a lot of attention currently and also support directions for the future. Additionally, it is discussed how the use of additive technology advances the creation of specialized acoustic structure designs. | ||||
