Introduction

### Course Review: Introduction to Acoustics (Part 2) on Coursera If you’ve completed "Introduction to Acoustics (Part 1)" and are looking to explore the practical applications of acoustics, then "Introduction to Acoustics (Part 2)" is the perfect sequel to your educational journey. This comprehensive course offers a deeper insight into acoustical concepts, guiding learners to apply their knowledge in real-world scenarios. #### Course Overview "Introduction to Acoustics (Part 2)" focuses on applying the foundational principles of acoustics to design and analyze various acoustic phenomena. Central to the course are advanced concepts such as the Kirchhoff-Helmholtz Equation, radiation, scattering, diffraction, and reverberation, which are crucial for anyone aspiring to work in fields related to sound engineering, architectural acoustics, or audio technology. #### What You Will Learn The course is laid out in a structured manner, progressing from fundamental concepts to complex applications: 1. **Radiation**: The course begins with the exploration of the breathing sphere problem, helping you understand sounds emitted from a spherical source and how it compares to the trembling sphere problem. This foundational understanding is critical as it sets the stage for analyzing sound radiation patterns. 2. **K-H Equation & Baffled Piston Problem**: You will delve into the Kirchhoff-Helmholtz equation, a pivotal concept in acoustics that describes how sound waves propagate in open systems. This week’s focus on the baffled circular piston problem provides valuable insights into practical noise reduction and sound control strategies. 3. **Diffraction and Scattering**: The course takes a hands-on approach to diffraction and scattering using the K-H equation established in the previous module. This section is particularly fascinating, demonstrating real-world applications like how sound waves interact with obstacles. 4. **Reverberation Period and Its Design Application**: Perhaps the most applicable section for future acoustical designers, students learn about reverberation time and how to leverage Sabine's theorem to design acoustic spaces effectively. By the end of this module, learners will be equipped to create acoustically optimized rooms. 5. **Wave Propagation in Space / Duct Acoustics**: In the final module, you will explore the Helmholtz Resonator and duct acoustics—a critical area in HVAC (Heating, Ventilation, and Air Conditioning) design and sound control in ducts. Understanding how sound behaves in these systems will provide you with the tools needed to address common acoustic challenges. #### Who Should Take This Course? This course is ideal for: - Acoustic engineers - Sound designers - Architects focusing on acoustics - Students in audio technology, physics, or engineering Whether you’re advancing your current knowledge or starting a career in acoustics, this course caters to both levels of learners. #### Recommendation If you are passionate about sound and its applications, I wholeheartedly recommend "Introduction to Acoustics (Part 2)."

Syllabus

INTRODUCTION

You will be going to learn breathing sphere problem, then compare with the trembling sphere problem.

First, you will learn Kirchhoff-Helmholtz equation, then you will adapt into the baffled circular piston problem.

Using Kirchhoff-Helmholtz equation that you have learned last week, you will apply into diffraction and scattering problem.

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.

For the last, you will learn Helmholtz Resonator and the phenomenon about the duct acoustics
