Always retain a copy of your correspondence with the noise creator and any reply. Remember, the noise might be the result of a misunderstanding. If the noise creator understands your position, he or she might modify their behavior or activity to suit you. If the noise creator is a business or a bone fide activity then approach the person who is in charge. This might be the licensee of a public house.
Profitable businesses are sometimes very sensitive to public complaints.
It can have some impact on their public image. Some businesses are answerable to the authorities. Some have to be licensed to operate. So it might be wise to remind the person in charge that there are higher bodies, including the board of directors, that you can complain to. Make sure all your evidence is presentable.
