It still a little confusing. The lecturer does not express the concept really clear. And there is lack of tons knowledge about how to get a solution of wave propagation.

Although this course is not designed especially for MOOC, you can still have a general idea of Acoustics. I want to take the Part 2 as well. Thanks for the effort made by KAIST.

The course uses videos with powerpoint displays within the video. Often the contents of the Powerpoint is not visually clear (ie too small to make out). You cannot download these powerpoints. My last straw was when I encountered a powerpoint (lecture 1 part 2 around 16:45 mins) when the video skips a section of the powerpoint slide. This meant that there is a reference to an equation which one has not seen. This is not just frustrating, but incredibly poor production. In maths/physics references to equations, eg Z, is meaningless unless you know what Z is!! Furthermore the lecturer refers to his textboook where " ... the derivation of the equation is shown" - the book incidentally is over GBP50! Don't waste your time on this risible course. Either find another decent MOOC from someone else or buy a book.

Interesante curso para entender qué se esconde detrás de las fórmulas

I recommend this course if you want to learn acoustics. I enjoyed this course.

Very informative and useful. The Teaching methodology is impressive.

Great course.
