Phone mics generally aren't the best and might not accurately portray how loud it is in your apartment. You should consider picking up a cheap SPL meter like this and showing what it's reading in your video.
Check Amazon, there are a ton in the $15-30 range. From the descriptions, they are all pretty much the same, just different batter sizes/capacities. They all come calibrated from factory and are within +- 1.5 dB accurate and they have 0.1 dB resolution.
I just chose this one since it was cheap, got good reviews, and I have a lot of rechargeable AAA batteries on hand. Works really well for me.
