Hearing is not just the reception of the sound – it also involves the processing of the sensory input in the brain.
A spoken sentence reaches our ear in the form of sound waves: it is collected and bundled by the pinna, amplified via the eardrum and the ossicles, and it then stimulates the sensory cells in the cochlea. These cells send the impulses along the auditory nerve which conveys the impulses to the auditory center of the brain.
In the brain, the signals are recognized as words and their meaning understood.

Information and ideas:
This process should be explained step by step.
It may be useful to make a comparison with a dynamo:
The pedaling on a bicycle moves the dynamo on the wheel, and something happens. The impulse is passed on, a lamp lights up; what happens in the hearing process is similar, as an impulse is sent to the brain, and there, too, “a light” goes on.
