About the Course:The course teaches how vibrating structures radiate sound. The student intending to take the course must have a good background in vibrations of continuous systems (like plates and shells) and acoustics. The course involves mathematical derivations and physical explanations. The material and homeworks will involve solving problems from current journal papers.INTENDED AUDIENCE: PhD students onlyPREREQUISITES: A fundamental course in acoustics and a course in vibrations of continuous systems are definite pre-requisites.INDUSTRY SUPPORT: Automobile, refrigeration and air-conditioning, all types of manufacturing industries, ship and submarine building companies, aircraft industry, washing machine industry.
