Acoustic waves are mechanical vibrations that propagate through a medium, typically air or water, as a series of compressions and rarefactions. These waves are generated by the vibration of a source, such as a speaker or a musical instrument. Acoustic waves are used in a variety of applications, including sound transmission, medical imaging (such as ultrasound), and communication systems. Researchers study acoustic waves to better understand their properties, behavior, and interactions with different materials and structures. This research area encompasses both theoretical modeling and experimental studies to explore the generation, propagation, and manipulation of acoustic waves in various environments.
