   But how can I obtain a impulse response if I don't have anything that
   makes such a impulse. I could clap in my hands (not very reproduceable)
   or use two pieces of wood etc...

How about a gun? :-)  

Somewhere back in my memory I seem to think that when acoustic
professionals do this they use an electric spark.  Practically I guess
that would mean the largest capacitor in your collection, or burning
up a small piece of wire with the AC line or a 12-volt car battery.
(Hey, this is why you got into electronics in the first place!)
