How to stop a door from slamming

The slamming of a door is both airborne noise (the sound of the actual door hitting the door frame) and impact noise, (the vibrations which can often be felt through the whole structure of the building). Airborne noise travels through the air and is picked up as noise, such as people talking, TV noise, music, cars and pets, e.g. dogs barking. Impact noise is the actual physical impact on buildings and solid materials, which generate soundwaves. The likes of footfall, furniture moving and in this instance, doors banging. 

However, there is a very quick and easy solution to stopping the noise created by a slamming door. This is to simply slow down the closing of the door with soft door close systems, (think back to the hydraulic hinges on doors when you were at school). Not something you'd particularly want on show within your home, althought there are domestic products on the maket whereby the soft close systems are integrated within the door and hidden from view.
