Psychoacoustic Modeling of Similar Sinusoids
- Plot the initial signal.
- Calculate the power spectrum of a single frame.
- Locate the tone maskers. Note that only one tone is found since the two sinusoids are so near each other.
- Locate the noise maskers.
- Eliminate any maskers that are weaker than another masker within one critical bandwidth.
- Calculate the thresholds resulting from each tone and noise masker.
- Sum the thresholds along with the absolute threshold of hearing to find the final global threshold.
