peaceful night

Can I have a peaceful night please? you guys have been practicing singing for the past few days and I haven't have a proper sleep before... when the exam started, midnight i hear people singing songs. I am frustrated at them but i can't do anything to them cause I think that is how they can release their stress... but please can you guys just give me one peaceful night? I am sick of hearing songs... my room gets hotter and hotter... and i just can't sleep with this temperature... please guys i need your cooperation
