I hope the 10am people don't go out after 6pm so that people with small children can get them to bed without being disturbed.
All our immediate neighbours have either children or grandchildren and the sound of footballs or trampolines or people enjoying their garden in the evening is part of living in a nice area where people have gardens that are used by the whole family. If you don't want to hear trampolines live in a flat (where you'll be longing for the neighbour's children to go outside early in the morning) or in the countryside (where the animals will keep you awake all night). Some noise is part of life and if you need silence outside until 10am then you are the problem, not the children enjoying their garden.
