There are four main components of aural rehab.
Detection
Discrimination
Identification
Comprehension
Each of the four areas are "harder" than the previous, and when moving through training, one would start with detection and move eventually to comprehension.
But what are these four levels?
Detection:
Also called awareness, this category has to do with recognizing the presence or absence of sound.
Discrimination:
In this category, a person would be able to say if two sounds are the same, or different.
Recognition:
In the recognition, a person is able to identify what the sound or word is.
Comprehension:
When comprehending, a person is not only able to identify the sound, but understands what that sound means. For example, upon hearing the doorbell the person would know to get up and answer the door.
