Why does my car shake at freeway speeds?
Have a tire shop inspect your tires and replace any that are dangerously worn or uneven. Another potential cause of a shaking, vibrating car at freeway speeds are worn suspension bushings, such as ball joints and control arm bushings.
Why does my car vibrate at 65 mph?
There are multiple problems that can cause a car to vibrate at speeds of 65 mph and above. The best solution is to methodically go through the problem areas that could cause this condition. If the suspension on your vehicle is out of alignment, it may cause the wheels to vibrate at certain speeds.
What causes low pitch rumble at 20 miles per hour?

How does highway traffic noise decrease with distance?
highway traffic noise decreases at a lower rate of about 3 dB for each doubling of distance. Considering only the cylindri-cal divergence phenomenon, this means that a highway traf-fic noise level of 75 dBA at 50 feet will reduce to 72 dBA at 100 feet and 69 dBA at 200 feet, a typical setback for homes adjacent to a highway.
What’s the road noise like at 70 mph?
Taking foot off gas at 70mph and coasting down to 30mph. Same as usual (loud buzz until I get around 60mph, then seems like road noise that gets quieter as I slow down). 10.

What is the sound level of a highway?
Considering only the cylindri- cal divergence phenomenon, this means that a highway traf- fic noise level of 75 dBA at 50 feet will reduce to 72 dBA at 100 feet and 69 dBA at 200 feet, a typical setback for homes adjacent to a highway. Of course, other phenomena will also influence the received sound level.
