About the Course

This course introduces acoustics by using the concept of impedance. The course starts with vibrations and waves, demonstrating how vibration can be envisaged as a kind of wave, mathematically and physically. They are realized by one-dimensional examples, which provide mathematically simplest but clear enough physical insights. Then the part 1 ends with explaining waves on a flat surface of discontinuity, demonstrating how propagation characteristics of waves change in space where there is a distributed impedance mismatch....

I heard something in this course which I have never heard before. The professor emphasizes on physical prospective of this course intentionally and this is very useful to describe the concept.

It is a very good course to introduce the basics of acoustics starting from one-dimensional cases to general 3D environments.

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.

Totally loved this course and learnt very keen to the concepts. Looking forward to pursue next course!

videos are so useful and informative. New concepts with live examples are so effective. Thanx

quite difficult to understand, had to reread and find sources from web to help (not too unusual). Really provides a good depth of mathematics and physical understanding of acoustics and some useful terminology and tricks.

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.

The course is really poor. Professor does not clarify passages and actually he uses a very peculiar approach to Acoustic (that is the impedance approach). Without a previous knowledge of the topic, the lessons are completely unclear. (a lot of math, that is fine! no problem with this. But many concepts are not explained, no mention on Fourier transform...). More over, it is clear that lessons come from a previous course and there are a lot of missing parts. I passed the final exam (no difficult) but overall really bad experience!

There're stuff that didn't get well enough, including the tests.

Hard to understand sometimes. The examples need to be better.

Terrible explanations, the professor is not clear and not methodical and is very boring. I will have to study acoustics again to actually learn it.

course, i enjoyed it very much, but be warned, you must have basic knowledge of basic phisics and math, understanding how derivatives work is esential. some people claim the teacher explains poorly, THIS SI UNTRUE explanations are very good but without understanding math and phisics you wont be able to follow so those who complain must grab a book first and git good. Also it has somwhat poor subtitles due to the writers sloppy work, some words apear out of context and some times an [INAUDIBLE] message apears, however I had no problems at all understanding professorYang-Hann Kim.

I am amazed by the depth of content covered in the course and the slow, methodical approach. The focus is more towards the practical aspects of Acoustics and Prof.Yang- Hann Kim manages to effortlessly connect formulas to intuition- this is indeed remarkable. The theoretical, math-intensive part is left for interested learners, which is also appreciable. I would recommend the course to anyone who is interested to get into Acoustics and would like to have a "feel around" before diving in-depth

Great course! It was well presented by the instructor in terms of developing concepts and mathematics, relating them to the real world, and then using simple, but effective, experiments to demonstrate concepts. The quizzes were good mix of questions addressing understanding of concepts and calculations relating to derived formulas.

The course gave me adequate knowledge about acoustic. Prof.Yang-Hann Kim delivered lectures in a good manner. The demonstrations between the lectures and examples are top level.

Thank you for sharing valuable knowledge.

This is a very informative course. It dives into the technicalities of Acoustics to the mathematics behind. I absolutely would recommend it to anyone who plans to get into the world of acoustic engineering.
