I could hear them from every point of my cell , at the top where security was high , on the right , in front of me behind me , at the bottom , and now unfortunately on left as well . I guess it was a problem that I had , but little noises bothered me . The vents did n't make anything easier . There was one on the left side of the room and one on the ceiling .

I would here too much background noise .
