Speech Perception in Geriatric Population
Abstract: Ageing is one of the characteristic features seen in organisms of the animal kingdom; after birth via ageing first the development and maturation take place which when progresses with time results in degeneration and ultimately ends with the end of the life cycle of the organism. As humans are no different; our maturation phase starts right after birth, which results in complete maturation by the time humans reach adulthood [1]. …
