Traffic vibration is mainly due to heavy trucks passing at relatively high speed on a road with an uneven surface profile.
Why is my car making a humming noise?
Especially if you don’t rotate the tires on time, the difference in treadwear could cause road vibrations and humming noises. If the sound gets even worse at a higher speed, tires are probably the cause of this problem. While getting a new set of tires might be expensive as well, it’s still much better than having to deal with mechanical repairs.
What is the main source of noise in a car?
As illustrated in the figure above, noise increases with vehicle speed. This figure also shows that at speeds above approximately 50km/h tyre noise becomes the dominant source of noise. At speeds less than 50km/h both vehicle (engine) noise and tyre noise contribute to the noise heard from the road.
How does road unevenness affect free field vibrations?
The dynamic component is induced by the road unevenness that subjects the vehicle to vertical oscillations. It depends on road unevenness, vehicle’s characteristics and vehicle’s speed. When the vehicle speed is low, as compared to the wave velocities in the soil, the contribution of the static component to the free field vibrations is negligible.

Do cars start slower in the winter?
Car batteries produce less electrical current when it’s cold, due to the chemical reaction being slower than on a warm day. Cold batteries simply don’t produce the same amount of power as warm batteries, and this effect can lead to starting issues.
Why is my car not starting in cold weather?
The starter motor therefore has less energy to work with when it tries to start the engine, and this causes the engine to crank slowly. All three of these problems can make it impossible to start an engine in really cold weather. People either keep their cars in heated garages or use “block heaters” to get around these problems.
Why does my car crank slower in the winter?
A lot of cars just tend to crank slower in the winter because the cold temperatures weaken the battery and because the oil’s a little thicker at cold temperatures, making the engine harder to turn over. It’s 100% normal, and nothing to worry about.
Can you start a car in the winter?
It’s much more difficult to start a cold car with a mostly-empty tank, so do yourself a favor and gas up often in the winter before letting the car sit. Replace your windshield wipers and wiper fluid. Wiper blades crack in the cold and become much less effective, which can be dangerous in inclement weather.
What happens if you run a cold engine?
The temperature of a cold engine also does cause vaporized fuel to condense on the cylinder walls which limits the amount of combustible fuel within the cylinder at the time of the spark. But that effect rapidly goes away once the engine is running and the cylinder walls begin to heat up.
