Why do different roads/streets have different noise volumes?

2.15K views

I’ve had to make this 80mile trip consistently that is 90% on interstate highways. I will listen to a podcast with my volume around 25. Then once I get on the interstate I will raise to 28-30 because I’ll be doing 70. I noticed there are some portions of road that I just dont hear the podcast anymore. Lasting 2-3 miles, sounding like when on a plane that is taxiing and getting ready to lift off. Then the next chunk is smooth and quiet.

The topography of the road changes, and what you hear are your wheels against the surface of the road.
