Neighborhood boys disturbing with noises all day and night

We are living on rent in flat floor no 1 in Kalol, Gandhinagar district of Gujarat. Almost since 5 months neighborhood boys of different age came and sit on banch under our flat. It's very much near to the balcony of our room approx 3-4 steps. They sit there almost anytime during day and night. Make noises, crake jokes, playing music loudly on phone. After each and every 2 hours they come and do this all things. At Morning, afternoon, evening and also at late night. I have my 4 months old baby girl who continueslly cry because she couldn't sleep during day and night because of the noises the boys make. I have requested them many times but they told me they will do whatever they like and will not stop making noises. I have requested neighborhood elders also but they keep saying that they will not stop them and it's my problem not theirs and I have to endure the situation. Since I am living on rent they think that they can make me suffer. Many times I thought to call the police but I don't know the laws. Please let me know what should I do.
