When My neighbor use water pump, I feel low frequency noise in room.
I think the noise come from sound wave,maybe add some resonance but I cannot feel vibration when I touch wall.
I try to talk with neighbor,before that I would like to record the noise as proof.
I have questions as below:
1.How to distinguish the noise,is that sound wave or resonance?
2.As I have only iphone and mono sound recorder,is that possible to record low frequency noise?

Thanks in advance.

Find a spectrum analyzer app for your phone. It might identify the frequency you are sensing.

You need to record the output of an accelerometer. Phyphox on your phone might work well enough. Good for the price...

I would suggest that you talk to your neighbor right away. Explain the situation, ask them to turn on the pump and come over to your place for a moment. Listening to the noise "live" will be the only way to get a perspective how noticeable and potentially annoying it is.
