Learners might have learned the basic concepts of the acoustics from the ‘Introduction to Acoustics (Part 1).’ Now it is time to apply to the real situation and develop their own acoustical application. Learners will analyze the radiation, scattering, and diffraction phenomenon with the Kirchhoff –Helmholtz Equation. Then learners will design their own reverberation room or ducts that fulfill the condition they have set up.

provide the textbook, it really helps you to accomplish the course much easier!

Part 2 was excellent!It would be nice to have reference to the text book, and also sometimes the questions in the quizzes are hard to stand because of the language.

Reviewed on May 15, 2018

A great course overall to understand the basic theory of acoustics. I have some suggestions. Quizzes need to be improved with more questions. I thought the quizzes were too easy
