Do your students hang from the rafters? Do the other teachers on the hallway complain as you have the loudest classroom on the hallway? If your class appears to act more like a circus than students engaged in a learning environment, then you may want to change the way you go about bringing order to your classroom.
Personally, I do not think that learning can take place until your classroom is disciplined enough for that exchange of information to occur. I understand that sometimes teachers do activities in their classroom that encourage students to interact with other students, thus creating noise, etc. However, I am primarily referring to students who are out of control in a learning environment, one in which a teacher is attempting to instruct his or her students.
