I am sitting on double storey terrace house and facing surau, just 40 meter away from my door step. I have been struggle for year, every early morning awaken by the prayer sound from speaker.
I have been looking for a sound proof solution a year, but can't find any contrator/services/solution locally here in Penang.
I would be very much appreciate if anyone can share with me the contrator or service provider name here in Penang.
