I’ve always heard that the decibel scale for hearing is logarithmic, and I’ve recently learned that our eyes view and compare objects logarithmically as well. How exactly does this process work, and is it different between the eyes and the ears?

Hearing occurs when your ear drum vibrates from a sound. When a sound occurs, the drum vibrates with it. When two identical sounds play, the drum vibrates more intensely. When 10 identical sounds play, the drum vibrates twice as intensely compared to a single sound.
Your eyes perceive light waves similar to the way your ears hear sound waves. One difference between these body parts is that your eyes have different mechanisms to alter or interpret the light waves before it reaches your brain. Light is scattered or focused through your clear jelly lens. The amount of light let in is controlled the black hole called the pupil. Then the cones and rods interpret this signal to build an image.
Sound is mainly interpreted by the intensity of air pressure in the drum.
