PSYCHOACOUSTICS ILLUSTRATE YOUR ESSAY WITH SPECIFIC EXAMPLES

Summary

In order to improve compression of audio files the psychoacoustic nature of the ear has been researched in considerable depth.  The ear is only capable of hearing acoustic pressure variations in the range of 20Hz to 20 kHz with the threshold of hearing varying depending upon the frequency. 

Conclusion

The psychoacoustic nature of the ear has been identified which stems primarily from the frequency filtering nature of the cochlea.  This filtering enables both simultaneous and temporal masking. An auditory signal can be made inaudible due the effects of another, more intense sound that occurs either before, during or afterwards. These properties can be researched experimentally to understand the exact characteristics of hearing to generate computer algorithms of these masking models.  These algorithms can then be used to compress audio data by eliminating sounds which are inaudible in order to maximize storage capacity.
