What is Sound? - Definition and Factors Affecting the Speed of Sound

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.

Mechanics of Hearing & How the Brain Processes Sound

2. 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.

Pitch and Volume in Sound Waves

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.

The Doppler Effect: Definition, Examples & Applications

4. The Doppler Effect: Definition, Examples & Applications

What is the Doppler effect? How does it affect our perceptions of sound and light? In this lesson, learn how traveling wave sources can change the way we observe sound and light waves. Explore the applications of the Doppler effect on shock waves, sonic booms, and the movements of distant galaxies.

How Sound Waves Interact: Definitions & Examples

5. 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.

Sound Quality: Definition, Differentiation & Noise

6. Sound Quality: Definition, Differentiation & Noise

How does your brain tell the difference between a note played by a guitar and the same note played by a piano? The answer has to do with sound quality, or timbre. Learn about the characteristics that your brain interprets to distinguish sounds.
