Psychoacoustic Modeling of Similar Sinusoids

1. Plot the initial signal.
   
2. Calculate the power spectrum of a single frame.
   
3. Locate the tone maskers. Note that only one tone is found since the two sinusoids are so near each other.
   
4. Locate the noise maskers.
   
5. Eliminate any maskers that are weaker than another masker within one critical bandwidth.
   
   
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.
