ACOUSTICS AS A COURSE IN THE UNDERGRADUATE PHYSICS CURRICULUM Farhat Surve Dept. of Physics, Nowrosjee Wadia College, Pune, MS, India

Three year BSc physics degree at UoP The problem: missing employability factor The solution: reorientation and incorporation of electives Acoustics - the working elective Organization and features Accreditation and growth

Three year BSc physics degree at UoP

The problem: missing employability factor

The solution: reorientation and incorporation of electives

Acoustics - the working elective

Organization and features

Accreditation and growth

Why electives? The goal Student must possess at least one skill-set in case of a post-BSc exit for employment Incorporate employment assisting content: develop modules depending upon the skills sought after by employers Content for acoustics was driven by industry: tasks for which consultancy was being sought at EARL

Acoustics as an elective Pilot course run at the final year BSc level- 1991, accepted by the BoS at UoP in 1992 Revised every four years thereafter Incorporated modules with emphasis on experimentation underlying theory and design Central to the course is the study of applied acoustics supported by simultaneous studies in electronics and computational physics
