Ok got a good one for you all: I have a music warehouse where several bands play in different rooms. The owner wants to condition all the rooms and meet the city requirements for ventilation. He does not want to use Ptacs in the place due to cost. The big problem is he does not want there to be any sound between the rooms thru the air ducts. He has several inside rooms in a warehouse about 15x15 in size not far from each other, sound proof walls.
I wanted to put a rooftop unit to provide air into each room but the sound is going to resonate thru the duct system into the other rooms. Does anybody have a suggestion that I could do to solve this, have to have ventilation in each room due to occupancy of the room.
