Eg. The purpose is to make the world heritage logo (layer 3) matched with outer mottled look circle (layer 1).

Step 1. Add a layer mask.

Step 2. Filter -> Render -> Fibers

Adjust the variance and strength according to your wanted effect.

Step 3. If you found the result is not ideal, then try another step. Image -> Adjustments -> levels

Adjust these 2 anchors to mix and match.

Step 4. Unlink this layer mask to adjust the effect position.

Tips: for pure text pattern, you may try different clouds filter. But the wired thing is the outcome effect may not look the same each time when you apply this filter.
