end corrections using 1/4 wave resonator
Hmm, ok. But surely at the closed end the pressure is a maximum and the speed zero? Wouldn't this be the best place to put the mic'?- blacko2k

end corrections using 1/4 wave resonator
Ok thanks, any pointers on where it can be moved to so that this set-up will work?- blacko2k

end corrections using 1/4 wave resonator
Hi, thanks for the reply, I've attached a quick computer sketch as i dont have a scanner unfortunately. If this isnt clear I'll try uploading a photo. Im sending a white noise source down the tube and attempting to use the red region in the image as a quarter wave resonator (as it is an...- blacko2k

end corrections using 1/4 wave resonator
Hi guys, Im investigating the magnitude of the end corrections of perforate pipes in the context of automotive exhaust silencers. Unfortunately I've hit problems quite early on: When investigating the natural frequency of my 1/4 wave resonator - initially with no perf pipe at all - the resonant...- blacko2k
