Anatomy and Physiology of Hearing

/in /by

Upon viewing the video on the Anatomy and Physiology of Hearing (the link can be found in Lessons – Week Two), describe the structure of the ear, focusing on the role that each component plays in transmitting the vibrations that enter the outer ear to the auditory receptors in the inner ear. Then, discuss the basic difference between determining the location of a sound source in the brain and determining the location of the visual object in the brain. Lastly, discuss the somewhat surprising outcome of research on hearing loss in urban versus rural environments, and the physiological explanation behind it. Support your belief and use specific examples. MINIMUM 300 WORDS

Introduction

Topics to be covered include:

  • The components of sound and how they interact
  • The function of the cochlea
  • Localization of sound

In this lesson, we will learn more about sound and the auditory systems that sound waves pass through as they are transmuted to signals the brain can understand. Sound travels as vibrations through the outer and middle ears before it is transmuted to electrical signals in the inner ear. We will also look at how we are able to identify where a sound came from, and how sound hits each of our ears.
