A s m r sound lets find out how we hear sound in the 1st place. Anatomically speaking we have an outer ear a middle ear and an inner ear and thats where we pick up the tourist signals in the form of vibrations in the cochlea to be precise. The cochlea is a bit like a spiral staircase that bassler membrane and hair cells make up the carpet. Its those cells that enable us to hear from behind notes. Notes sound fiber asians deflect the hair cells its like flattening the fibers of a carpet. That generates an electrical signal which is sent to the brain and we perceive a sound. Then stand up again and all ready for the next sound. The different pitches are registered in different parts of the cockpit. I know its are detected by the hairs at the bottom. Lower ones further up. And the lowest notes at the very top. Enabling us to hear a wide range of pitches. And their cells are very sensitive if theyre exposed to too much stress or for too long they can be damaged and move on the real sounds
