Using the Fletcher-Munson curves of equal loudness, rank the following tones by decreasing loudness (1=loudest). Remember that the horizontal axis is marked as a logarithmic scale. The divisions between the far left and 100 represent 20, 30, 40, 50, 60, 70 ,80 and 90. The divisions between 100 and 1000 represent 200, 300, 400, 500, 600, 700, 800, and 900.
1. A 70dB tone at a frequency of 1000Hz
2. An 80dB tone at a frequency of 20Hz
3. A 70dB tone at a frequency of 10,000Hz
4. A 70dB tone at a frequency of 3,000Hz
For number 1, its right about at 70
For number 2, its about 81
For number 3, its about 75
For number 4, its about 72
So the order is, 2, 3, 4, 1 from loudest to softest
Using the Fletcher-Munson curves of equal loudness, rank the following tones by decreasing loudness (1=loudest). Remember...
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...
