Acoustic study is the branch of physics that deals with the study of sound and its properties. This includes the study of the generation, transmission, and detection of sound waves, as well as their effects on the environment and living organisms. Acoustic study is used in a wide range of fields, including architectural acoustics, environmental acoustics, bioacoustics, and industrial acoustics. In architectural acoustics, it is used to predict and control sound levels in buildings, while in environmental acoustics, it is used to predict and manage noise pollution. In bioacoustics, it is used to study the behavior and communication of animals, and in industrial acoustics, it is used to optimize the design and performance of products such as speakers and mufflers. The study of acoustics is essential for understanding and mitigating the impact of sound on human health and well-being. CFD can be used to simulate and predict sound behavior in different environments and help in design of noise control measures.
