Use Audiogram #2: If masked air conduction testing was needed to test 4000 Hz the right ear, what would the initial masking level be according to the Plateau Method? Assume the patient wore insert headphones during the testing. (Choose One)

Use Audiogram 4: What level would you anticipate the patient’s SRT would be in the left ear? (Choose closest answer)

What best defines the term Threshold? (Choose one) 

Use Audiogram #3 True or False: Bone conduction results in this test (Audiogram 3) represent best bone conduction thresholds with the bone oscillator placed on the left.

A low pass filter does which of the following? (Choose One)

What does Air Conduction testing help us understand? (Choose all that apply) 

Which word type has two syllables of equal stress? (Choose one)

True or False: Standardized audiometric testing became available around World War I.

Use Audiogram #4: True or False: A “no response” symbol indicates that the patient could not hear the stimulus even at the amplitude limits of the testing equipment.

For this multi-part free response question, you may use the text box below to type in your answers if no equations, diagrams, or illustrations are involved. Otherwise, please write down your answer on blank papers.  You have 10 minutes after you have completed this Honorlock exam to scan your handwritten answer (or take photos) and upload into Canvas (responding to the assignment “Exam 1 Supplement”). Make sure you label the individual parts clearly. FRQ1: Electron conduction in metals (13 points) The temperature dependence of the electrical resistivity of Cu is shown in the figure below. From the figure, we can identify three temperature ranges where the resistivity show strikingly different temperature dependencies: (i) at T < 4 K, the resistivity is nearly temperature independent (i.e.,
