课程概况
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.
课程大纲
INTRODUCTION
RADIATION
You will be going to learn breathing sphere problem, then compare with the trembling sphere problem.
K-H Equation & Baffled Piston Problem
First, you will learn Kirchhoff-Helmholtz equation, then you will adapt into the baffled circular piston problem.
DIFFRACTION AND SCATTERING
Using Kirchhoff-Helmholtz equation that you have learned last week, you will apply into diffraction and scattering problem.
REVERBERATION PERIOD AND ITS DESIGN APPLICATION
Now you will learn very practical acoustical phenomenon. With reverberation period and Sabine's theorem, you will be able to design an acoustical room that satisfies given condition.
WAVE PROPAGATION IN SPACE / DUCT ACOUSTICS
For the last, you will learn Helmholtz Resonator and the phenomenon about the duct acoustics
