13.811 is split into two segments: structural dynamics for the first half of the semester and acoustics for the second half.
NOTE: Only the acoustics component is available on this site. The structural dynamics component has not yet been incorporated into OCW.
The chapters referred to in the table below are from the text: Williams, E. G. Fourier Acoustics: Sound Radiation and Nearfield Acoustical Holography. Burlington, MA: Academic Press, 1999. ISBN: 9780127539607. (Background Reading: Section 1)
