Hi!
I'm sorry but your video won't prove anything if you're not talking. I'm just hearing all the background noise from your environment.
If I make a video in my home, then I will clearly hear the refrigerator 5 meters from where I record but once I start talking, my voice is clear and easy to hear.
The microphones will pick up your surrounding noise differently compared to your ears. Human hearing is very good at filtering out different background noise and you can do this with a microphone too but during video recording and video calls, it's set to pickup sounds coming from everywhere. It's by design.
