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
