hello, I finished my draft air bearing tonearm and I'm facing a problem of noise of air flow captured by the cartridge.
My air pump is totally soundproof, so it is not in question, to be on I did a test with a bottle of compressed air and noise (very slight) persists.
I must therefore reduce the noise at the holes on the arm ... my piercings have a diameter of 0.7 mm ... I saw that almost all the arms of this type have holes of 0.3 mm if I make a new tube drilled to 0.3 mm can that solve the problem? My pump at a rate of 40 liter per minute and delivers a variable pressure of 100-350 mbar, I can adjust the flow ....
It there any advice or experiences on this problem? ... Thank you for your response and suggestions!

Lost in translation?
Does your cartridge pick up the noise?
Then turn the holes away from the cartridge.
Or is it direct noise from the holes?
Playing with the flow can perhaps solve your problem as long as the arm keeps sliding

BTW 0.7 mm piercings are way to small for your avatar🙂

Hey!"earsandeyes"🙂 I thought to direct air diffusion holes 45 °?
..... I'll try to see ...? the "piercing" of my avatar ...... is not on the 0.7 ....sure !!😀

Hello Sourdingue!
I feel less alone now (it is at least two "Frenchy")
If I understand correctly, it hears the sounds of air in the tube and it goes back into the cell?? I made a lot of arm cushion of air (this is my hobby and I'm on a project now) and I had these worries at the beginning. It must be a reserve of air buffer capacity (tube drainage pipe) and above, fill the tube holder of foam to prevent flutter in the tube. The holes must be the smallest possible diameter for a maximum speed of air leaving the hole.
