Swooshing noise as car drives near obstacles

    Car Noise
In summary, when driving with windows open, the sound you hear is caused by the continuous stream of air hitting your face. However, when driving past an obstacle like a tree, the swooshing noise is caused by the car's own motor and air turbulence noise being reflected back to the driver, creating a doppler effect. This is especially noticeable when driving next to a wall. If the airflow is interacting noticeably with the tree, it may be wise to back off a bit.

As you drive with your windows open you can hear a sound due to some continuous stream of air that is hitting your face, or whatever. But why is it then, that when you drive past by some obstacle, like a tree, you hear a swooshing noise? What is causing this?

Typically you're hearing tire, mechanical, and maybe some aero noise being reflected back to you. It's especially obvious when you drive next to a wall.

If you're driving close enough to a tree that your airflow is interacting noticeably with the tree, then you may want to back off a bit. :smile:

Very well put. I laughed.

You finally hear how noisy your car is.
 

1. What causes the swooshing noise as a car drives near obstacles?

The swooshing noise is caused by the air passing through the gaps between the car and the obstacles, creating turbulence and generating the sound.

2. Is the swooshing noise normal or does it indicate a problem with the car?

The swooshing noise is normal and does not indicate any problems with the car. It is a result of the aerodynamics of the car and the air flow around it.

3. Can the swooshing noise be reduced or eliminated?

The swooshing noise can be reduced by keeping the car clean and free of any debris or dirt that may create more turbulence. However, it cannot be completely eliminated as it is a natural occurrence during driving.

4. Does the swooshing noise affect the performance of the car?

No, the swooshing noise does not affect the performance of the car in any way. It is simply a byproduct of the car's design and does not impact its functionality.

5. Are there any safety concerns related to the swooshing noise?

No, there are no safety concerns related to the swooshing noise. It is a common occurrence and does not affect the safety of the car or its passengers.
