Acoustics is a branch of the science of physics that focuses on waves of sound as they interact with objects, people and structures. Students may learn about amplifying sound waves, diminishing or abating noise using scientific methods or the use of underwater acoustics.

Master-level studies involve specialized study in a field of research or an area of professional practice. Earning a master’s degree demonstrates a higher level of mastery of the subject.
Earning a master’s degree can take anywhere from a year to three or four years. Before you can graduate, you usually must write and defend a thesis, a long paper that is the culmination of your specialized research.
