S2-4 Acoustical Transducers

The course is held in the 1st and 2nd period of 2011. Most literature consists of excerpts from (unfortunately) rather expensive books, so they will be provided to you in terms of xeroxes at least one day before each lecture, except if from Kinsler et al.'s "Fundamentals of Acoustics" (4th ed.) since you are expected to have that book already.

Unless otherwise announced, the dates, topics and literature will follow the schedule below.
