Course Objectives
• To understand the principles of acoustics covering generation, propagation and radiation of sound • To learn techniques for measurement and reduction of noise
Course outline
• Wave motion in strings, bars, beams and plates • Acoustic wave equation • Sound generation and radiation • Reflection and transmission of acoustic waves • Human response to noise and noise criteria • Sound measurement and instrumentation • Sound in enclosed spaces • Sound absorption • Acoustic enclosures and barriers • Sound propagation in ducts; mufflers • Vibration control
Venue for the practical class: Instrumentation and control lab (II-355) Books:
1) Fundamentals of Acoustics (John Wiley & Sons; 4th Edition (2000)), Lawrence E. Kinsler, Austin R. Frey, Alan B. Coppens, James V. Sanders 2) Noise and vibration control engg: principles and applications, I. Ver and L. Beranek Wiley, 2006
Evaluation Scheme:
Major: 40%, Two minors: 20%+20%, Assignments, Quizzes and Practical: 20% Attendance Policy:
Attendance will be calculated with 1P for every lecture attended and 1P for every practical attended. A minimum of 75% combined attendance in lectures and practical is required. If attendance of a student is <75% but >60% then the grade of the student will be reduced by two grades. If the attendance is <60% then the student will be awarded an F grade irrespective of his/her total marks in the course.
