The sound coming out from the back

Hi, when I sit on the back seat of my 106 xr car, I get the sound out of the back
Generally, when you sit on the back and turn to the right, the sound is more after passing through the heights.
Thanks for your help in advance

My brother was in me, I do not know the same voice, left comes from the back, or as if right from the right, it might have changed in the car as if the car had gotten stuck, it should have changed.

But there are traces of knock in the rear right tire.
