Psychoacoustic Modeling of Separated Sinusoids

1. Plot the initial signal.
   
2. Calculate the power spectrum of a single frame.
   
3. Locate the tone maskers. Note that the tones are very far apart.
   
4. Locate the noise maskers.
   
5. Eliminate any maskers that are weaker than another masker within one critical bandwidth. Because the tones are far apart, there should be no maskers eliminated.
   
   
6. Calculate the thresholds resulting from each tone and noise masker.
   
   
7. Sum the thresholds along with the absolute threshold of hearing to find the final global threshold.
