Strange Air Trap

[Falb, John]

Most likely it has to do with sound dampening. 
Just a guess.

Hi all,
  a mechanic friend of mine has asked me on several occasions if I could
explain a strange type of air trap that is on 80+ autos.  Today he asked
again.  Here are the particulars:
  1994 Chevy S10, 4.3L V6.  On the air intake tube, close to the radiator
support, there is a small opening on the top of the tube less than an inch
square, that leads to a large, molded, plastic buble.  This plastic buble is
empty and does not have anything attached.
  My guess is that it is some kind of air dampener.  
  Does any body know why?
