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

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

Sound is a longitudinal wave that travels through various states of matter, like solids, and not through a vacuum. Discover the definition and factors affecting the speed of sound including nature of sound waves, mediums, and the wave equation.

Mechanics of Hearing & How the Brain Processes Sound

2. Mechanics of Hearing & How the Brain Processes Sound

The brain processes sound from the vibrations of sound waves against the components of the inner ear. Explore the mechanics and components of the ear and discover how they allow the brain to interpret vibrations in the air as different sounds.

Pitch and Volume in Sound Waves

3. Pitch and Volume in Sound Waves

In sound waves, pitch is the frequency of sound and volume is the intensity of sound. Explore the parameters of sound, the definitions of amplitude, intensity, and frequency, and the acoustic range.

What are Decibels? - Definition & Examples

4. What are Decibels? - Definition & Examples

Have you ever heard of decibels? Do you ever wonder what they are and how they are used? This lesson explains what decibels are and provides examples of how they are used.

The Doppler Effect: Definition, Examples & Applications

5. The Doppler Effect: Definition, Examples & Applications

The Doppler effect explains why a sound's pitch seems to change depending on whether it's coming towards you or moving away from you. This lesson investigates how the Doppler effect works, and how it can be applied to the behavior of both sound waves and light waves.
