No we just want the shortest loudest sound we can get initially.  I will get it 
dialed in after some initial testing.  
The problem with the starter pistol is that I think the sound comes out of an 
area that is somewhat diffuse.  If we put a blank in a pistol then the sound 
should come from the barrel.

Starter pistol would be significantly louder and is pretty cheap to use if you 
need to do this often.   You can get .22 or .32 caliber blanks.   Don’t bother 
with the black powder blanks, they are harder to get and cost more.   The black 
powder only helps if you need visual verification of the shot before the noise 
reaches you (like the timer in a race).

I need to launch a large sound impulse down a pipe.  Thinking of a starter 
pistol.  Banging on the side of the pipe is not good enough.  

Need a loud pop that I can do over and over.  Whatever makes the noise need to 
be small.  

Not sure if there is a small loudspeaker that could produce an impulse sharp 
and loud enough.  

Do they still make cap pistols?  Not sure if toy caps would be loud enough or 
not.
