MODELLING OF HUMAN AUDITORY SYSTEM AND. HEARING DEFICIENCY' CLASSIFICATION

Abstract

Recognition of the recent growth of interest, in the study of human sensory systems, has prompted advanced coagulation of engineering principles and applications with human physiology and bio-•rnedicine. In a field as diffuse as biomedical engineer-ing the sensory processes, perhaps, find the latest areas of extensive research and deep study; the most important reason being that they are quite complicated. Their complexity is worth unraveling, if for no other reason than the fact that whatever we know about the or-1d is based on what we find out through the senses. The senses impose limits on what we know and they bias our understanding of the world. All the sensory information is analysed, changed, abstracted and finally stored in the form of. knowledge in the brain. A large portion of the brain--cortex, of our nervous system is devoted to audition. Recent researchers have commented that favourite sounds, melodies and speeches not only speed up recovery of hospitalized patients but also help to a great extent in, -evoking to st memories and, curing minor brain disorders. In ancient India special mantras and sutras were chanted to revive and improve concentration, cure all sorts of illness and purify the senses.'
