I understand...use R13.
Your explanation does raise another question. We are having the 6" walls and rafters of the winery insulated with polyurethane spray foam. Each of the contractors told us the open cell spray foam is an excellent sound barrier to help keep loud music or movies inside the building so as to not irritate the neighbors. By your explanation, their thinking is flawed?
