One of the most common ways people circumvent the door slamming problem is to install pneumatic
Install hydraulic door closers
Hydraulic or Pneumatic door closers are a great way to prevent your door from slamming, and they can be used on both internal and external doors. These work by using either air or oil pressure to slowly close the door, rather than it being gravity that does it.
You could add those small felt circle pads (or small clear rubber bumpers for cabinets and drawers) to the door frame. I did that in my house, one in the top corner one right in the middle behind the door catch (hole for door latch/strike plate) and one in the lower corner just above the carpet.
Grab one or two felt pads and stick them inside the door frame. You can put them around the lock area, or spread them out closer to the top and bottom. The pads will catch the door before it hits the frame. While it won't completely silence the slam, it will quiet it, providing you some protection from the sound.
Attach a few felt pads to the edges of your door frame and both the top and bottom parts of the strike plate. The self-stick felt pads will provide soft padding against your door when it closes and prevent it from slamming shut. These are also a solution if you're trying to figure out how to make a door close quietly.
To make it more efficient at blocking noise, you need to add mass and close air gaps. To do so, there are many products available. These include acoustic door sweeps, gaskets and caulk. You can also add acoustic curtains and other materials to the door.
Slam Strips. Mounts to the Side of One Door, of a Double-Door Set-Up, to Stop the Other Door From Swinging in too Far.
If the hinges weren't installed properly or the screws are loose, the door may be out of plumb—or not level to the frame. To check this, open the door to a 90-degree angle from the frame and use a level on the side of the door. If the door is leaning, it may be causing the door to slam—as well as other issues.
The door-in-the-face technique is a compliance method commonly studied in social psychology. The persuader attempts to convince the respondent to comply by making a large request that the respondent will most likely turn down, much like a metaphorical slamming of a door in the respondent's face.
Consider using a door sweep (a.k.a. weather stripping)
Acting also as draught-excluder, a door sweep (sometimes called door seals or weather stripping) looks just like a brush that runs along the entirety of the bottom of the door to slow down its movement.
Doorstops are one of the hardest working, but least noticed pieces of hardware in your home. They protect your walls, cabinets, and furniture from being damaged by a swinging door, while also preventing your doorknobs from being scratched and dented.
Typically made from rubber or other soft materials, these small components are crucial in preventing doors from slamming loudly. The primary function of a door silencer is to provide a quieter closing action by cushioning the metal-to-metal or wood-to-wood contact that occurs when a door is closed.
Weather stripping fills the cracks and gaps around doors and windows, reducing the amount of air leaks and eliminating drafts or cold spots. Homeowners can save an average of 15% on heating and cooling costs by weather stripping their homes and adding insulation.
A spike strip (also referred to as a spike belt, road spikes, traffic spikes, tire shredders, stingers, stop sticks, by the trademark Stinger or formally known as a Tire Deflation Device or TDD) is a device or incident weapon used to impede or stop the movement of wheeled vehicles by puncturing their tires.
Chicken tenders (also known as chicken goujons, tendies, chicken strips, chicken fingers, or chicken fillets) are chicken meat prepared from the pectoralis minor muscles of the animal. These strips of white meat are located on either side of the breastbone, under the breast meat (pectoralis major).
Replace Door Hinges-
Replacing door hinges is a straightforward method to prevent doors from banging against walls. Opt for spring-loaded hinges, which automatically close the door gently, reducing the chances of it slamming.
Turn the screws clockwise to increase the force with which the door closes (or rotate counterclockwise to decrease it);
It is a kind of noise-cancellation system. It is done by adding layers of dampers to the doors of the vehicle in order to prevent the sound waves from entering the vehicle. This is a very handy feature and is quite pocket-friendly too, much like the modern-day car insurance online policies that you must get.
Door dampers catch closing doors before the thud. They then - softly and silently - close them completely. Whether the movement was triggered manually, or due to the wind or airflow.
