Sound: Crash Course Physics

The video explores how sound cues shape our environment and delves into the nature of sound as a wave. It explains sound waves as longitudinal and pressure waves, and how they are detected by devices like microphones and eardrums. The video discusses pitch and frequency, including the human hearing range and ultrasonic and infrasonic sounds. It also covers the relationship between loudness and intensity, the use of decibels for measuring sound, and the Doppler effect's impact on sound perception.
