The singing is pretty loud. First of all, not to mention the singing is not good, even with this volume to play records for people who do not want to listen to the people are considered a nuisance, not to mention that I'm a rather inaccessible to the people can hear a lot of out of tune, broken sound. At the same time, I've asked students who have meetings in the office building and play games in the dorms, and they can all hear it, that's the premise.
My school is relatively small, usually only one playground at night, that playground is connected to three dormitory buildings and a student, guide office building. Every Friday and Saturday (in fact, sometimes mid-week), there will be people dragging the stereo open loud singing in the playground. The playground is also a lot of running, or chatting with sisters, couples, or memorizing vocabulary, telephone students.
