The purpose of this portion of the project is to see how many wavelengths of a tone it takes for a human ear to recognize that it is a tone.
Subjects were played 3 related tones for five seconds each. Then they were played selected number of wavelengths of those tones and asked if they could identify them. The test tones began at 1 wavelength and got increasingly longer.
For the low range, the average was 9 wavelengths. For the middle range, it was 6. For the high range, it was 15.
Overall, the average number needed was 11 wavelengths.
