Acoustics is the study of sound, how it is produced, transmitted, and received. It encompasses a wide range of topics including the physics of sound waves, the properties of different materials in relation to sound, and the application of sound in various fields such as music, communication, and medical imaging. Acoustics also includes the study of noise control and the design of spaces to optimize sound quality. Researchers in acoustics use a variety of tools and techniques, such as mathematical modeling, experimentation, and computer simulations, to study and manipulate sound waves for practical purposes.
