We Might Use Spray Foam Insulation to Deaden the Sound of Our Band

Our band has definitely got to find a new place to practice. My dad won’t let us use the basement any more and the garage isn’t sound proof enough. The neighbors always complain if we get really wound up out there. Dad says that we need to find a place that has a layer of spray foam insulation to deaden the sound. I asked him if we could possibly spray some insulation into the basement or garage, but I’m not sure that he will bite. I told him that I just knew it would make enough difference. He might agree to let us stay in the garage if we are willing to do the work.
