Sound into Signals

Sound vibrations can become electrical energy through the principle of electromagnetic induction, which means the creation of an electro-motive force (EMF) by way of a moving magnetic field around an electric conductor. Electromagnetic induction generates electrical current using a magnetic field. When a magnetic field and a conductor, such as a wire coil, move in relationship to one another, electromagnetic induction occurs.

The cochlea, which is the spiral cavity of the inner ear containing the organ of Corti, which produces nerve impulses in response to sound vibrations, is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain so you can hear music or sound in any situation

Figure 1 shows visuals of an animated ear and brain to people who need to see it but can’t hold it in their own hands. It shows what sound waves even look like, the ears and ear canal, the brain, and the different three sections of the ear, and the auditory transduction, which is Auditory transduction refers to the process of converting sound waves into electrical signals that can be processed by the brain. The auditory nerve carries these electrical signals from the ear to the brain.

Figure 2 shows a Flowchart that people can read and follow along with to get and understand how, where, and with the visuals in Figure 1 can make you understand your own ears and brains to hear and understand what the sound, music, movies, videos, etc are trying to say or try to explain in their own ways.
