The aim of the course is to provide the students with a basic understanding of the Acoustic. Both of indoor and outdoor acoustic wave propagations will be discussed. Several various examples of application of acoustic analysis of mediums in engineering applications will be presented. This is essentially useful for the graduate students who want to deal with multidisciplinary design fields. They need to develop and apply their abilities in several various fields including of mathematical and physical background of acoustics, computer programming and specific application in every field from hearing acoustics to structural acoustics, vibroacoustics and acoustic of music instruments. The students will be provided with a comprehensive formulation derivation.Then several important topics and definition will be presented. Finally some applied problems will be discussed.
