audio telescope?
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.
