About This Chapter
Sound Waves & Hearing - Chapter Summary
The lessons in this chapter provide a concise, yet information-packed overview of sound waves and hearing. This chapter offers an opportunity to grasp how sound waves interact. You can also review treatment options for hearing impairment. After completing the chapter, you should be prepared to:
- Recall factors that affect the speed of sound waves
- Discuss the impact of constructive and destructive meeting of waves
- Explain pitch and volume in sound waves
- Describe how sound waves interact with your ear
- List causes of hearing impairment
Each lesson comes with a brief quiz to determine how much of the content you can remember. You can study all of the lessons or just focus on specific topics. Make the most of this resource by printing the quiz in worksheet form to study offline.
1. What is Sound? - Definition and Factors Affecting the Speed of Sound
Explore the minute workings of sound waves and how they travel. We'll discuss the main factors that affect the speed of sound waves, and we'll try some mathematical problems involving the wave equation.
2. How Sound Waves Interact: Definitions & Examples
Sound waves move through the air and hit your ear. If sound waves collide, they change the wave and ultimately how you hear the sound. How the wave changes depends on whether the waves meet constructively or destructively.
3. Pitch and Volume in Sound Waves
What do pitch and volume mean when talking about sound waves? Further your understanding of sound waves in this lesson as we explore the more familiar aspects of sound. We'll learn about pitch and volume and how they relate to sound wave parameters.
4. Mechanics of Hearing & How the Brain Processes Sound
How do our ears transform sound into signals that our brains can process? In this lesson, you'll cover properties of sound waves and how they interact with key parts of the ear.
5. What is Hearing Impairment? - Definition, Causes & Treatment
This video lesson discusses hearing impairment, from the different types and their causes to available treatment options. Following the lesson is a short quiz to test your knowledge.
