Is it wind noise, road noise or engine noise?

Wind noise you can replace worn gaskets + add additional gaskets to certain areas, commonly sold on lelong and China online retailers. Not too pricy and easy to DIY.

Road noise no cheap way. 3+ year old car it's about time to look at your suspension bushings d. Pay attention to the bottom and top of each spring, there should be a piece of rubber. This one usually gets hard after awhile, cheap to replace but you need to remove the springs which is not easy. All 4 springs maybe take half a day for workshop, DIY can take a whole day. As your shock absorber get older also road noise will increase.

Currently doing soundproof on my car, everything diy. It's not expensive but alot of labour. If send to shop mark-up is generally high. Doors make the biggest difference (biggest flat sheet of metal on your car). But road noise is very hard to reduce. Easiest and quickest option is add additional layer of carpet.
