shower pipes noisy

The second story shower makes loud noise as soon as it it used. There is some sound produced when the water is used, but the loudness is really ramped up when the shower head is turned on. The sound does come frome the pipes (which one?)and sounds like a jet engine. The deafening noise can be heard throughout house, loud enough to alter conversations. Can this be caused by air cavitation in the pipes? If so how is it eliminated?

If the shower control valve is a two-handle type, it may be a loose washer on one side or both. The flow of water causes the washer to flutter as water flows past.

To fix it, and/or check it, turn off the main water valve, and remove the stems on both the hot and cold, and check that the washers are held tightly in place. Replace the washers while you're at it.

There is a single control knob. Pull for on, push for off, left hot .... does this have the same loose washer issue?

No.

But it could be some obstruction that's lodged against a port in the control valve or elsewhere in the pipes. You might dislodge it:

If you have access to an air compressor, hook it up at the shower head connection, shut of the main water, and open the outside faucets, and then blow back thru the system.
