A noise ordinance would be helpful.

The school at Wat Klang is surrounded by a six foot high concrete block fence topped with statues of animals; rabbits, lion, tigers, geese, etc. The back of the school, the window side, is about thirty feet from the fence. There is a busy street immediately outside the fence.
The street is filled with noisy tuk-tuks, motorcycles, trucks and worst of all trucks equipped with loudspeakers blaring. They are moving shops. Some are selling fruit, others meat, food, etc. The students are so accustomed to the din that they do not register any notice of the noise. But it makes it very difficult to hear students as they work to get English pronunciation.
