A musician is walking home alone late one night and is startled when a dog in a yard to his left barks unexpectedly. Respond to each of the following regard- ing the musician's ability to hear the bark. sTrace the path that the sound waves travel as they enter the ear and pro- ceed to the receptor cells for hearing. sTrace the path that the neural impulses created by the bark travel from the receptor cells into the brain. sUsing two theories of pitch percep- tion, explain how the brain might process the pitch of the dog's bark. sExplain how the musician would know that the bark originated to his left even without seeing the dog.
