Course Description

All energy consuming systems emit acoustical sound, which give us information we need to know including danger. However, sound may also prevents us enjoying music or give us unpleasant feelings, as noise. Thus, it is very important to control sound or noise from various system. Objective of this silence amenity engineering course is to understand sound radiation theory and mechanism which is necessary to improve our acoustical environment.


Overall grading will be given based on student presentation (50%), and report (50%).

Course Goals

Objective of this silence amenity engineering course is to get basic understand of sound radiation theory and mechanism, which is necessary to control the noise.
