first you should have somone drive your car while your in the back seat and listen for the noise. if you think your door seals are leaking heres a few ideas:

put a light coating of baby powder on the seals and gently shut the doors while holding the door handle open (door wont latch, you dont want to compress the door seals anymore then if the doors were latched, in otherwords to slam it), open door and inpsect for "soft" areas in the seal where the powder looks different (lines not as thick etc).

nother trick, take a dollar bill and put it in the door seal. you should be able to pull it out with slight drag, not too much, but more then no drag. there will be a lot of opening and closing of the door for this lol.

put making tape over all the "seams". go around the door and drive and see if the noise is there. add it to the window seams and see if the noise is still there. in otherwords if you tape up EVERY seam the first time, you wont know what is leaking.

try those and see what happens. i recommend doing the tape thing first.
