I have a venturi system I use for both veneering and vacuum pot work.
The venturi is nice for less noise as you point out, It only runs when there is a demand.
Of course the airflow makes noise just like using your air hose to blow stuff off (full flow)
These are rated in CFM requirement and you can find a variety where one should match up with your compressors capability. You should have an accumulator on the vacuum side (I use two 10" sections of 3" pvc arranged like SCUBA tanks). I probably would not use a venturi if there is significant leakage expected just because I have the sound of my compressor kicking off every so often.
Advantage over a pump is they can be very fast.
