How does energy change from acoustic to mechanical to hydraulic to electrochemical?
It sounds like you're talking about an ear?
The acoustic energy is a vibration in the air, which hits the eardrum, thus becoming mechanical energy, this travels through bones in the ear to the oval window. Behind the oval window it is filled with fluid, thus transferring to hydraulic energy as the fluid becomes in motion. This fluid presses on a membrane which transfers back to mechanic energy which hits many small hair cells lining the cochlea. the hair cells are attached to nerves. As the hair cells are pressed an electrical discharge takes place, thus converting the energy to electrochemical so the brain can process it.
