Learning Objective:

To extend the basic concepts of acoustical analysis and specifically to study wave propagation, sound radiation, absorption and transmission in a manner directly relevant to noise control practice. Information of this sort is required to design effective noise control treatments.
 
  1. Extend fundamental concepts of acoustical analysis to engineers with an emphasis on the wave approach
  2. Study wave propagation, sound radiation, absorption and transmission
  3. Apply fundamental concepts to noise control practice
