MATHEMATICAL MODEL ON HEARING MECHANISM (STATISTICS PROJECT TOPICS AND MATERIALS)

 

ABSTRACT

In this thesis, we present a mathematical model that describes the fluid motion in the inner ear and the behaviour of the basilar membrane for such motion. The equation of the fluid motion in the inner ear was solved using the potential flow theory since the fluid is considered to be incompressible. The obtained solutions show that the velocity potentials of both chambers are the same.

 

CHAPTER ONE

1.1 INTRODUCTION

Hearing is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous matter.

In humans and other animals, hearing is performed primarily by the auditory system. Mechanical waves in form of vibrations are detected by the ear and transduced into nerve impulses that are perceived by the brain.

The ear is one of the major senses in the body and like vision, is important for distance warning and communication. It can be used to alert, to communicate pleasure and fear. It is a conscious appreciation of vibration perceived as sound. In order to do this, the desired signal has to reach the higher parts of the brain. The function of the ear is to convert physical vibration into an encoded nervous impulse. Like a microphone the ear is stimulated by vibration. In the microphone, the vibration is transduced into an electrical signal, while in the ear into a nervous impulse which in turn is then processed by the central auditory pathways of the brain…..
