Binaural Audio: The Power of Sound Illusions

The video tutorial introduces the concept of audible allusion, encouraging viewers to close their eyes and use headphones for an immersive experience. It explains binaural audio, where two similar frequencies create a third sound, known as a binaural beat, which affects brainwave activity. The tutorial concludes with a fact about Harvard's brain bank, which stores over 7,000 human brains for research.
