How to make a PDF look grainy / aged / poorly photocopied?

I know the title sounds strange, but i am looking for a way to make a PDF look like it's photocopied from an old, worn out , piece of paper. Specificaly, for music scores. I have some original music compositions tha I wrote out in a scoring program, and I want to export the pdf, and use some program or AI to make it look like it's a photocopy of an old , worn out manuscript for a personal art project.
