How your ears translate physical vibrations into electrical thoughts
In short: Discover the physics of sound, from how waves travel through different materials to the biological process of how your brain interprets noise.
Sound is a physical wave that moves through various media. While the frequency of a sound wave remains constant as it moves from one material to another, its wavelength changes in direct proportion to the speed of sound in that specific medium. Waves can also be manipulated through reflection, refraction, and absorption.
The human ear acts as a biological transducer. It captures physical vibrations and converts them into electrical signals that the brain can interpret as specific frequencies and intensities. For context, the human hearing range is generally recognized as 20 to 20,000 Hz.
