The Receptive Transducer for Aural Communication is the ear. It is the Perceptual processes, however, that enable us to hear.
The receptive transducer, that converts sound waves back into electro-chemical impulses, is the ear.
As remarkable as the ear is (and we will talk about it in depth later), it is nothing more than a transducer. It simply changes energy form.
Hence we do not really hear with our ears. That is an even a more complex process left to the devices of the brain itself. That is basically the realm of perception.
Perception is the structuring and organizing of those impulses that have been transduced.
It is the interpretation of those impulse patterns by the brain which become the NOW of our existence.
It is a bundle of neurological processes that work together to give us the experiences of sight, sound and touch.
We will be talking in detail about many of these process later, but let me give one example now.
