Nuisance noise

Between the times of 5 pm to 9 pm most evenings, and the weekends. When the instructor is teaching taekwondo to students, we have him shouting and screaming at the top of his voice, We also then have kids screaming and shouting back to him. blowing a whistle during lessons, which is causing stress This becomes very annoying very quickly And as summer approaches they have the shutter door open, which just magnifies the noise they produce straight in our direction,as we live directly opposite We have now put up with this for a three years now and getting to a point where it's affecting our mental health. It reducers the amount of time we can sit in our front garden after work and try to relax, we have to shut the windows so to muffle noise. Why should we have to suffer, what have I done to deserve this Why should we have to listen to this noise pollution, when I just want to relax after a hard day's work
