Use the Fletcher-Munson curves of equal loudness to answer the following questions. Remember that the horizontal axis is marked as a logarithmic scale. The divisions between 100 and the far left represent 90, 80, 70, 60, 50, 40, 30, and 20. The divisions between 100 and 1000 represent 200, 300, 400, 500, 600, 700, 800, and 900.
What is the minimum threshold of hearing in intensity level (decibels) for a tone at 9000 Hz? (Do not enter units)
What is the loudness of a 65 db tone at 9000 Hz? (Enter the answer in phons. Do not enter units.)
What is the intensity level required for a 700 Hz tone to have a loudness of 20 phons?
Homework Answers
