When sound waves hit it, the skin vibrates. It moves the vibrations to the three tiny bones (called ossicles) in our ear. These little bones transfer the sound to the cochlea, which is full of fluid. The cochlea is part of our inner ear. It houses the Organ of Corti, which has sensory hair cells called stereocilia.

Sep 12, 2023 · Sound waves travel by making atoms and molecules shake or vibrate. They can move through solids, liquids, and gases. For example, when you hit a drum, it makes the drum’s surface vibrate. These vibrations move through the air as sound waves. When these waves get to our ears, they make our eardrums vibrate too.
Sound waves are vibrating energy that look like waves. The waves are made of microscopic building blocks called molecules. Sound waves travel back and forth through solids, liquids and gases to ...
Sound waves may travel through many mediums. These include air, water, and solid objects. Sound waves pass through mediums in all directions. Third, some kind of receiver, such as the ear of a person, picks up the sound waves. The ear changes the sound waves into signals that travel to the brain. The brain understands these signals as sound.

Volume. The volume of sound is the measure of loudness. To quantify volume we use decibels. The more decibels, the louder the sound is. A soft sound, like a whisper will measure around 15-20 decibels. A loud sound like a jet engine is more like 150 decibels. The threshold of pain occurs at around 130 decibels.
