I bought this over at ebay for $30 and installed today.

Car Door Auto Noise Rubber Sealing Strip 2pcs Fit Hyundai 2012 2013 Santa FE DM | eBay

It is a set of rubber strip that goes in between door to seal and reduce outside noise. Installation is very simple and took me less than 10 minutes to get done. Do I feel the difference after the install? I'd like to think so but it is hard to tell, so I tested.

I ran a same course 4 times; twice without the strip, and twice with the strip installed, and measured noise level at idle, 40mph, and 70mph. AC was off and noise level was measured while I was running on cruise control. The road was isolated with minimal traffic to reduce possible interference from other cars. and... here is the result. They were fluctuating ±1~2 but I averaged.

Before:
0mph - 60dB
40mph - 73dB
70mph - 80dB

After the install:
0mph - 60dB
40mph - 72dB (Difference = 0.5~1)
70mph - 79dB (Difference = 1~1.5)

So yes, there definitely was a difference in number though it's not distinct. Maybe 0.5~1dB. Is it worth the money? I don't know honestly. It is your call :)

This is what I used to measure noise level. Can't say it is accurate but good enough for relative comparison :)

most of your noise will be coming the tires within the wheel wells, and noise entering from the cabin pressure release flaps.

if you want to really reduce the sound - start by spraying your wheel well splash guards. hit them with a bed liner style coating. the rest of the noise is wind hitting the windshield, grille, side view mirrors, and outside noise coming in from the pressure release flaps behind the rear bumper. door jamb weather stripping is really only to keep water out.

For $30, this hardly seems worth the effort.
agreed.

$30 could have gotten 23 songs from iTunes/Google Play to drown out any wind noise! lol

That's a good idea. Maybe I should look into undercoating and see how much it improves.
