This episode I describe how our ears and nervous system decode sound waves and gravity to allow us to hear and make sense of sounds. I also describe protocols for rapid learning of sound and other types of information. I discuss sound localization, doppler effects (sound motion), pitch perception and how we isolate sounds in noisy environments. I also review the scientific findings on binaural beats and white noise and how they can improve learning. Other topics and protocols include tinnitus, sea sickness, ear movement, ear growth and the science-supported ways we can all accelerate learning using "gap effects".   Thank you to our sponsors: ROKA - https://www.roka.com - code: huberman InsideTracker - https://www.insidetracker.com/huberman Headspace - https://www.headspace.com/specialoffer   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman   Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab Website - https://hubermanlab.com Neural Network - https://hubermanlab.com/neural-network   Links: Review on spacing effects and learning: https://bit.ly/3qM6bto  Micro-rest and accelerated learning: https://bit.ly/3hitXKM  Ear movement: https://bit.ly/2TrS9Bf  Ears making sounds, hormones: https://bit.ly/3yneKgV  Binaural beats: review and references: https://bit.ly/36fggFO  Timestamps: 00:00:00 Overview of Topics 00:02:20 Protocol: New Data for Rapid Learning  00:09:10 Introduction: Hearing & Balance  00:13:53 How We Perceive Sounds 00:21:56 Your Hearing Brain (Areas)   00:23:48 Localizing Sounds 00:28:00 Ear Movement: What It Means  00:33:00 Your Ears (Likely) Make Sounds: Role of Hormones, Sexual Orientation  00:35:30 Binaural Beats: Do They Work?  00:43:54 White Noise Can Enhance Learning & Dopamine 00:51:00 Headphones 00:55:51 White Noise During Development: Possibly Harmful 01:03:25 Remembering Information, The Cocktail Party Effect 01:12:55 How to Learn Information You Hear 01:18:10 Doppler 01:22:43 Tinnitus: What Has Been Found To Help? 01:30:40 Aging: How Big Are Your Ears? 01:35:00 Balance: Semi-Circular Canals 01:40:35 A Vestibular Experiment 01:43:15 Improve Your Sense of Balance 01:48:55 Accelerating Balance 01:51:55 Self-Generated Forward Motion 01:56:25 Dizzy versus Light-Headed 01:58:38 Motion Sickness Solution 02:01:23 Synthesis
