How does the speed of sound differ through solids, liquids and gases and how does differ to the speed of light?
Sound travels fastest through solids (5000m/s). This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it
Sound travels faster in liquids(1500m/s) than in gases(330m/s) because molecules are more tightly packed.

How are sound waves entering an ear, converted into electrical signals, and then sent to the brain?
-
The sound waves enter the ear and are directed to the eardrum through the ear canal. The eardrum then vibrates making the ossicles vibrate. These vibrations are then led to the cochlea which makes the liquid inside shake. This then travels through the ear canal where it is transformed into electrical impulses to reach the brain through the auditory nerve.
