Those interested in becoming financial advisors will make the decision to either go independent by establishing an investment advisory firm of their own, or to pursue employment as investment adviser representatives (IARs) with an existing investment advisory firm.
How hearing works. When these sound waves reach the ear, they travel down the ear canal and hit the eardrum, making it vibrate. Three tiny bones in the middle ear link the vibrating eardrum to a tiny bone structure in the inner ear called the cochlea. The cochlea is filled with liquid that carries the vibrations to thousands of tiny hair cells. The movement in the fluid causes the cells to carry a message to the nerve that is connected to the brain, which turns the signals into what you hear.
Hearing pathway: sound Â» ear Â» nerve of hearing Â» brain. 1  The cochlea is a biological microphone. 2  Its job is to turn the mechanical vibrations of sound into electrical signals in the nerve of hearing.  The electrical signals â digital â are then sent up into the brain, where you hear things.
