Job - Silence your neighbour
My neighbour is very noisy and they don't decrease it no matter what. If someone can build the setup or come with their plan to achieve the goal, I can pay whatever you demand.
My neighbour has 3 loudspeakers and 2 big-box speakers. He uses an amplifier with a CD in it. He also uses few mics sometimes for his band to sing. they sometime sing for 24 straight hours.
Please help and advice.
