I faced a similar problem long time ago in another country where I had to repair a high pressure hose for Power steering, the new one was steel braided and was very loud, The original hose was fibre braided.

Is the original fibre braided hose availible anywhere?

When it comes to hydraulic parts it's best to buy OEM. Recent research at a large pump manufacturer showed that they could take an average of 5 dB(A) out of a standard power unit merely by changing the configuration of the hydraulic hose.
