The optimal cost/precision/effort way is to use RoomEQ Wizard freeware with your laptop. You can get away with RS meter for this but a better mic is advised.
This will give you measurements of swept tones (without resorting to pen-and-paper or spreadsheet entries) and will also provide lots of other info.
