This educational infographic explains how sound travels through compressions and rarefactions and introduces important wave properties such as frequency, amplitude, wavelength, and speed. It also shows how the human ear collects sound, how the eardrum and middle ear transmit vibrations, and how the cochlea converts them into electrical signals that the brain interprets as sound. 🧠👂 From speech and music to phone calls, radio, television, and public announcements, sound waves play an essential role in communication and everyday life. Sound connects us all! 🔊✨
