Playing sound without displaying the graphic?

I'm trying to use Mathematica to set up a demo of 12 Shepard tones. 
(See Gray  and Glynn's _Exploring Mathematics with Mathematica_ for a
discussion.)   I'm creating a button palette with the 12 tones arrayed
in a rough ring  (it's ugly, but it works).  The problem is, each time
I play a tone, a  large block of output is created in the Notebook
front end (if it  matters, I'm using Mathematica on a Windows NT 4.0
machine).  When I play the  whole sequence of 12 tones, it means 12
blocks of wasted space, each  about 2 inches high in my configuration. 
All I want is to hear the  tones, and not to have to delete lots of
useless output cells.

I can make the waveform graph stop displaying by setting the Prolog to 
something, but the output cell is still generated.  I can't figure out 
how to muck around with $SoundDisplayFunction or any of the related 
internals.  Seems like I must be missing something obvious.  Is there 
some way I can play tones without eating up Notebook real estate for 
unneeded output cells?
