Extracted text: Table 1 below shows the threshold for hearing in the left ear of three students at the indicated range of frequencies. Draw the pure tone audiogram for the three students on a single graph with the scales as illustrated below. Comment on the reasons for the shape of the graph for student 2 and 3. Table 1 Pure tone audiogram of the left ear Student 1 Student 2 Student 3 Hearing Level (dB) Hz 125 -5 5 60 250 -5 10 55 500 5 60 1000 10 60 2000 -5 20 55 4000 -5 70 60 8000 40
