Is the high decibel radio gymnastics every morning at school a nuisance and illegal?

Absolutely nuisance, I got married for the convenience of future children's school, bought a school district housing, the location of the school is particularly close, sometimes I do not work, probably from seven o'clock more than the beginning of the noise, feel so many years, only when the children's vacation to have a good rest, our downstairs aunts go to the school to let them reduce the decibel, but the school did not improve, so there is definitely a Disturbance of the people.
