We start with the environmental stimulus, the vibrations, being produced. Next, attend to this stimulus. The stimulus (the vibrations) then hit the receptors (the eardrum). Transduction occurs, creating an electrical signal that is sent to the brain, where it begins processing the signal. We then perceive the vibrations as sound; we hear it. After we perceive it, we recognize it, giving the sound meaning (this is affected by our experience). Lastly, we take action which changes the perception and starts the process over.
