Why Do Open Car Windows Make Noise?

Why Do Open Car Windows Make Noise?

According to Erie Insurance, the phenomenon where the slow-moving air inside the cabin clashes with the fast-moving wind outside the vehicle is known as Helmholtz Resonance. This results in a loud noise as the two pockets of air compress and decompress.

Wind buffeting occurs when the air inside the car thumps against the faster-moving air outside the window when just one window or the sunroof/moonroof is open. This is due to the compression and decompression of the two bodies of air when they clash.

When a single window is opened at speed in a car, causing wind throb or buffeting, the noise stops when a second window is rolled down. This phenomenon is known as Helmholtz Resonance, which is the same principle that causes a bottle to hum when blown into.

Is the noise from open car windows caused by wind resistance?

The second factor contributing to increased noise in cars is wind resistance. The sound of wind moving around and through the car can significantly raise the overall noise level. Wind noise is a frequently encountered issue for car owners and drivers, especially when the vehicle is in motion. Understanding the causes of these noises can aid in finding solutions to reduce them.

How does the shape of the car window affect the noise level when open?

When the hole in the window is too large, the velocity of the escaping air is insufficient to significantly impact the direction of the wind passing over the edge. Consequently, it does not create a build-up of resonance. Therefore, the window must be open only to an extent that allows for the energy needed to initiate resonance, while ensuring that it does not decrease the Q (quality factor) of the car.
