PS a pluged up drain does not make noise, just a real mess. What it can do if plugged up in the past is back up and plug up the vents.

Like bubbling toilets and drains gurgling, sometimes when the line is really full and close to coming out in a tub or, shower and the level goes back down it can make a toilet seem to flush as well.
If you do decide to call a real plumber make sure that he cleans drains too so you at least have a 50/50 shot at having him be able to fix your problem.
