What is Sound about?

Sound is a mechanical energy that travels as a pressure wave, involving compression and rarefaction of particles. The Doppler Effect describes the change in frequency as the sound source moves, while infrasonic sounds are below 20 Hz and ultrasonic sounds are above 20,000 Hz. Sound reflection creates echoes, which require a reflecting surface to be at least 17.2 meters away for clarity.
