Doors can slam shut due to a sudden change in air pressure caused by drafts, wind gusts, or closing windows. The force of air rushing past the door can cause it to close forcefully.
So let us take a closer look at the inquiry
Doors can slam shut due to a sudden change in air pressure caused by drafts, wind gusts, or closing windows. The force of air rushing past the door can cause it to close forcefully. However, let’s delve into this phenomenon in more detail.
Interestingly, an abrupt change in air pressure is responsible for various everyday occurrences, and slamming doors are no exception. When a door is left slightly ajar or a window is opened or closed rapidly, it creates a draft by displacing the air in the surrounding area. As a result, there is a sudden increase or decrease in air pressure inside and outside of the room.
This fluctuation in air pressure sets off a series of events that ultimately leads to the slamming of the door. When the pressure inside the room is higher than outside, the door tends to get pushed open. Conversely, if the pressure outside is greater, the door is forced to close. This is because the air tries to equalize the pressure on both sides, and the force generated pushes or pulls the door with significant strength.
As for the science behind the slamming, Bernoulli’s principle comes into play. According to this principle, an increase in the speed of a fluid (in this case, air) results in a decrease in pressure. As the wind or draft rushes past the partially open door, the air velocity increases, leading to lower pressure on the outside of the door. This discrepancy in pressure across the door causes it to move abruptly, resulting in a sudden slamming shut.
A quote from Arthur C. Clarke, a famous science fiction writer, further emphasizes the impact of air pressure on doors: “Any sufficiently advanced technology is indistinguishable from magic.” This concept of doors slamming shut due to seemingly mystical forces can indeed pique our curiosity and make us appreciate the underlying scientific principles at work.
Here are some intriguing facts related to doors and air pressure:
- The Guinness World Record for the loudest door slam is 129.6 dB, which was achieved in 2015. That’s louder than a rock concert!
- The speed at which a door slams shut can reach up to 10 mph, depending on the force of the air pressure change.
- Slamming doors can be a safety hazard, especially for children or pets who may get their fingers or paws caught in the door frame.
- In medieval times, castle doors were designed to be thick and heavy, making them resistant to slamming shut from prevailing winds.
Illustrating the various air pressure scenarios and their effects on doors can be done with a simple table:
Table: Air Pressure Scenarios and Door Movement
| Air Pressure Inside Room | Air Pressure Outside Room | Door Movement |
|---|---|---|
| Higher | Lower | Pushed open |
| Lower | Higher | Slammed shut |
Understanding the reasons behind door slamming can enable us to take preventive measures, such as using doorstops or adjusting window openings, to minimize the occurrence. So, the next time a door slams shut unexpectedly, you can appreciate the science behind it rather than considering it a mere inconvenience.

Kevin Starr from Lakhdar Security provides a comprehensive explanation on how to adjust a door closer. He breaks it down into four main adjustments: spring power, back check, closing speed, and latching speed. Starr advises using a screwdriver and an Allen wrench to make the necessary adjustments. It is crucial to work on the door while it is closed and the closing ring is non-operable. He suggests starting with 1/8 turns and periodically checking progress to evaluate if further adjustments are required. Additionally, Starr mentions that some adjustment screws may be labeled, while others may require referencing the diagram inside the closer.

Air Pressure The effect of displacing air requires more force because that air is contained. The more windows open the more force which exists. Opening a window means wind blows through and looks to find a path through the house. When it goes through and past a door it provides the force needed to slam it shut.
Doors slam shut due to pressure changes in areas near the door. When air moves from an area with high pressure to an area with low pressure, it can cause a door to slam shut. For instance, a window left open in the next room can cause an open door to slam shut. Another reason for a slamming door is an inadvertently heavy-handed household member who exerts more force than necessary to close it.
The most common reason has to do with pressure changes in areas near the door. Pressure changes occur when air moves from an area with high pressure, to an area with low pressure. For instance, a window left open in the next room can cause an open door to slam shut.
The obvious reason for a slamming door is an inadvertently heavy-handed household member who exerts more force than necessary to close it. But when a gentle touch leads to a loud noise, or the door slams when no one’s near it, there’s probably one of two culprits afoot.

But when a gentle touch leads to a loud noise, or the door slams when no one’s near it, there’s probably one of two culprits afoot.
Similarly one may ask, Why do INFJs slam doors?
The answer is: INFJs slam the door when they have been deeply wounded. They slam the door when they can no longer tolerate a person’s toxicity. They do it to protect themselves from further hurt.

To keep a comfortable temperature in a living space, it is rarely necessary to move so much air that doors slam shut. And what happens after the doors slam?
Just so, What causes a door to slam shut?
As a response to this: When air moves from a high-pressure area, i.e., your home, to a low-pressure area, i.e., outside your home, the pressure change can cause the air to slam your door shut. Faulty Door Hinges: Door hinges are meant to control how a door opens and closes.

Additionally, How do you stop a door from slamming? When everything is plumb, the door slamming should cease. Try a few felt pads. If slamming continues after adjusting the hinges, or the issue is caused by air pressure or cross breezes, try some of the self-stick felt pads normally used to keep décor from scratching furniture.
