Which field of study focuses on sound and its interaction with objects of various shapes and materials?

The field that focuses on sound and its interaction with objects of various shapes and materials is acoustics. Acoustics examines how sound waves are produced, transmitted, and received, as well as how they interact with different environments and materials. This includes studying phenomena such as echo, resonance, and sound absorption, which are essential for applications in architecture, audio engineering, and even medical imaging. Acoustics encompasses both the physical properties of sound and its practical implications in various fields, making it a distinct area of study.

Dynamics, in contrast, primarily deals with the forces and motion of objects rather than sound specifically. Kinetics focuses on the relationship between the motion of objects and the forces acting upon them, and thermodynamics studies the relationships between heat, energy, and work in physical systems. These fields do not encompass the specific interactions and properties of sound waves as acoustics does.
