Engineering Acoustics

Course Description

The course introduces acoustics principles and uses extensive examples to instill techniques needed to leverage the knowledge for many applications. By such broad introduction, course participants are exposed to a variety of ways by which acoustics principles are encountered in engineering and science. The approach cultivates an expansive skillset for participants to apply the knowledge to new technical problems.

Students must have completed ME3260, or graduate standing, or received approval from Dr. Harne. 

Objectives 

  • Introduce fundamental concepts of acoustical system analysis and design
  • Understand linear wave propagation phenomena, including radiation, absorption, and transmission of sound from and through simple structures/materials and in enclosures/rooms, and understand human perception of these wave propagation behaviors
  • Acquire essential knowledge and skills to participate in fundamental practices of engineering noise control, architectural acoustics, and sound source modeling
  • Explore introductory aspects of diverse acoustics applications to understand underlying physics shared by all and how common strategies of analysis and design help identify acoustic system implementations with best performance and quality
