Transduction in psychology can be the process of converting energy into neural impulses, or electrical signals, that we perceive as reality. Sound waves enter the ear and get transformed (transduced) into neural impulses in our brains that we interpret as sound. The same thing applies for every form of energy that we can interpret, like heat, touch, and taste, or even the nasty look your mother-in-law is able to give you which is somehow the only freezing-cold physical sensation you can feel deep inside the thickest of bones.
