There is nothing you can do to your house to reduce the noise inside the house.
And the constant noise is very stressful and the stress may hurt your health.
Sometimes, a group of people who live near the airport will contact their political representatives and ask them to work with your group to make the airport close earlier or use other runways to reduce the noise.
If that is not possible, it may be best to sell your home (even if you lose some money).
Sometimes, losing money but gaining a peaceful life is the best choice.
Change your place.
