课程名称:声学导论(第二部分) 课程概述:学习者在“声学导论(第一部分)”中可能已经掌握了声学的基本概念。现在是时候将这些知识应用于实际情况,并开发自己的声学应用。学习者将利用基尔霍夫-赫尔姆霍兹方程分析辐射、散射和衍射现象,并设计符合设定条件的混响室或风道。 课程大纲: - **引言**:介绍课程的基本内容和目标。 - **辐射**:学习呼吸球问题,并与颤动球问题进行比较。 - **基尔霍夫-赫尔姆霍兹方程及有隔音板的活塞问题**:首先学习基尔霍夫-赫尔姆霍兹方程,然后将其应用到有隔音板的圆形活塞问题中。 - **衍射与散射**:使用上周学习的基尔霍夫-赫尔姆霍兹方程,应用于衍射和散射问题。 - **混响时间及其设计应用**:学习混响时间这一实用的声学现象。通过萨宾定理,学习者将能够设计出符合特定条件的声学房间。 - **空间中的波传播 / 风道声学**:最后,学习亥姆霍兹共鸣器及风道声学现象。 该课程旨在提升学习者的声学分析能力和实际设计技能,使其能够在实际应用中解决声学相关问题。
Name:INTRODUCTION
Description:
Name:RADIATION
Description:You will be going to learn breathing sphere problem, then compare with the trembling sphere problem.
Name:K-H Equation & Baffled Piston Problem
Description:First, you will learn Kirchhoff-Helmholtz equation, then you will adapt into the baffled circular piston problem.
Name:DIFFRACTION AND SCATTERING
Description:Using Kirchhoff-Helmholtz equation that you have learned last week, you will apply into diffraction and scattering problem.
Name:REVERBERATION PERIOD AND ITS DESIGN APPLICATION
Description: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.
Name:WAVE PROPAGATION IN SPACE / DUCT ACOUSTICS
Description:For the last, you will learn Helmholtz Resonator and the phenomenon about the duct acoustics
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.
