   Hmm, the size of the observed image isn't directly related to   
   the nature of light waves emanating from them.  The closest analogy   
   I can think of is the following... when you get your vision tested,   
   you go from large letters down to small letters.  When you get   
   your hearing tested, you go from loud sounds to increasingly   
   quiet sounds (ignoring pitch and color blindness).  So by that   
   analogy, running the sound through an attenuator rather than   
   through an amplifier would be one thought.
