Live in an apt. Style condo. The wall behind where we sit in the living room has the water pipes for our neighbours shower. Unfortunantly when the neighbours shower or bath it gets noisy. The section of wall is about 12 feet wide with 8 feet ceilings. What are some things i can do as far as insulation or other things to reduce noise of running water. Willing to rip out section of dryw all and redo if necessary.
