I have heard something similar to short burst of noise only once in
my 80 CD collection, that was when I brought home Frida's "Somethings
Going On Around Here" CD.  I looked very carefully at the substrate
containing the digipits and noticed some bubbles in the vinyl covering
about a half inch span toward the outside of the disc (the noise occured
during the last song).  I attribute the noise to the inability of the
error correction logic to handle the high number of errors that were
occurring.  Note that on my Sony CDP101 the sound of the noise was
also muted.  In any event, the disc was obviously defective so I returned
it for another which works just fine.  I recommend that you try your
discs on the same model of CD player at your stereo dealer and see if
the same noises persist.  Also look at the substrate with a magnifying
glass to check for any obvious defects, remember, CDs play from the
inside to the outside of the disc.
