Об этом курсе: 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.
Для кого этот курс: This course is primary for the experts on the acoustics. Learners better take 'Introduction to the Acoustics Part 1' beforehand.
