just knock door and ask them be polite lo... if they wanna to be rude, then nothing can be do...

like opposite my house's indian neighbour, previously having praying quite oftenly and his house have a small temple... and they start the events, visitor coming in, and the neighbour become "bomoh" or "monkey king", scream there scream here, fly there fly here... especially the screaming sound caused the ignorance to all the neighbour and other neighbour's children starting to shout with the "bomoh" together... i took a short video clip how the neighbour scream and scream... but now started dont have such events anymore, so temporarily i just forget it 1st... if have the events again will record it down, wait till i felt the most ignorance feeling kicking in i will report to police with video clip and request them to dismantle the small temple from our neighbourhood
