Chapter 45.3, Problem 3R

Summary Introduction

To explain:

The action potential caused in different acoustic neurons due to different frequencies of pressure waves in air.

Introduction:

The outer ear acts as a funnel to conduct different frequencies of pressure waves through to the eardrum. The pressure waves cause vibrations in the eardrum. These vibrations created by the different frequencies of pressure waves are carried from one part of the other, finally reaching the different acoustic neurons present in the inner ear.
