NV real estate investing question

[Eric Wu]

I am currently in escrow for a rental property in Las Vegas.  My 1st one.   

The property I am buying is west of 15FWY, 1.5 miles  Allegiant stadium, away from the airport.   I just realized we can hear and see commercial plane in and out of the airport.  the flight path is not directly above us but I can see it standing outside and hear the noise....It's not that loud but nonetheless, i can hear it and see the airplane if I look up.

Then I went back to see the seller disclosure and air plane noise was not disclosed.  My question is aren't they suppose to disclose that?
