In this episode, Dr. Huberman describes how our ears and nervous system decode sound waves and gravity to allow us to hear and make sense of sounds. He also describes protocols for rapid learning of sound and other types of information. He discusses sound localization, doppler effects (sound motion), pitch perception and how we isolate sounds in noisy environments. Dr. Huberman also reviews the scientific findings on binaural beats and white noise and how they can improve learning. Other topics and protocols include tinnitus, seasickness, ear movement, ear growth and the science-supported ways we can all accelerate learning using “gap effects.”
