 * PsychSim 5: THE AUDITORY SYSTEM **


 * Name: ___ Section:__ **

__**Date: **__

__This activity explores how we hear and how the physical nature of the sound wave determines the qualityof the sound experience. __

__**The Auditory System **__

__  What are the four tasks of the auditory system? __

__1. Pick up stimulus energy from the world around us. __

__2. Change that energy into a pattern of neural impulses. __

__3. Carry those impulses to the proper locations in the brain. __

__4. Process the information carried in the pattern of impulses so that the stimulus can be identified. __

__**Structure of the Ear **__

__  What are the three main regions of the ear and their associated parts? __

__1. Outer Ear – Pinna, Ear Canal and Eardrum. __

__2. Middler Ear – Ear Canal, Hammer, Anvil, Stirrup. __

__3. Inner Ear – Semicircular Canals, Audiotory Nerve, Cochlea __

__**The Sound Wave **__

__  <span style="font-family: 'Times-Roman','sans-serif';">How are sound waves like ocean waves? __

__<span style="font-family: 'Times-Roman','sans-serif';"> Sound waves are like ocean waves in the fact that it also has crests (peaks) and throughs (valleys). __

__  <span style="font-family: 'Times-Roman','sans-serif';">What are the three aspects of sound waves? __

__<span style="font-family: 'Times-Roman','sans-serif';">1. Frequency __

__<span style="font-family: 'Times-Roman','sans-serif';">2. Amplitude __

__<span style="font-family: 'Times-Roman','sans-serif';">3. Waveform __

__**<span style="font-family: 'Times-Bold','sans-serif';">Frequency: The Rate of Vibration **__

__  <span style="font-family: 'Times-Roman','sans-serif';">Which type of tuning fork would vibrate faster—a small, short one or a large, long one? Why? __

__<span style="font-family: 'Times-Roman','sans-serif';"> A short one because it produces a smaller sound wave. __

__  <span style="font-family: 'Times-Roman','sans-serif';">How is frequency measured and calculated? __

__<span style="font-family: 'Times-Roman','sans-serif';"> The number of times a wave goes up and down each second. __

__**<span style="font-family: 'Times-Bold','sans-serif';">Frequency, Amplitude, and Waveform **__

__  <span style="font-family: 'Times-Roman','sans-serif';">The frequency of a sound wave determines the __Pitch __of the sound we perceive.__

__  <span style="font-family: 'Times-Roman','sans-serif';">The amplitude of a sound wave determines the ____Loudness__ __of the sound we perceive.__

__  <span style="font-family: 'Times-Roman','sans-serif';">The waveform of a sound wave determines the ___Amplitude___ of the sound we perceive.
