When a door is moved, if there is any "sticking"' in the hinge mechanism (or contact at the jamb), there may be a continuous "stick-and-release" action. This may result in mechanical vibration which will produce sound. Sound is the mechanical energy released through the air (and through the door, too) based on some kind of harmonic motion in the door's component parts, and stimulated by moving the door. Science explains what the sound is and how it was generated in this instance. Should we have a meter, science could allow us to measure the sound.
At times a creaking sound.
a door a frog
The cast of Creaking of the Door - 1996 includes: Todd Gorang as Son
A creaking sound usually is the shocks or struts. It is best to have a mechanic look it over to make sure.
