if you're really going to measure db, get a real SPL meter and a good one.
phone + apps can vary over 15dB right off. 3dB is twice the sound level, not 10dB. then add the phone's pre-programmed audio software that calibrates max performance of that mic in that housing, add multi-array setup phones that actually CANCEL noise outside the polar pattern you got basically a super biased reading of your cabin.
kinda like measuing horse power via your butt.
