Module 1 - Physical Acoustics

Intro :: Acoustics :: Vibration :: Waves :: Resonance

Vibrating Systems Physical systems that vibrate will do so at one or more unique frequencies. In this chapter you will learn about simple harmonic motion, vibrating systems, complex vibrating systems, and you will be introduced to vibration in musical instruments. To successfully complete this chapter you should... Read chapter 2 in your text book (pages 19 - 32). Carefully study the important concepts. Be able to determine the frequency of vibration for simple harmonic motion of different systems. Be able to describe the motion of complex vibrating systems as harmonic or non-harmonic. Important Concepts Simple harmonic motion Mass-spring system Pendulum Spring of air Helmholtz resonator Multiple mass systems Degrees of freedom Vibrational modes Vibrating bodies Vibrating strings Vibrating membrane Vibrating bar Vibrating plate Air-filled pipe Modes Complex vibration Animations Mass-String (SWF) Mass-Spring (SWF) Pendulum (SWF)
