As it became known, the solid and confident sound of closing the door of your car is developed by engineers who are engaged in psychoacoustics – the science that analyzes and reflects the perception of sounds by a person.

Although most people do not think about the sound that a vehicle door makes when closing, auto companies pay quite a lot of attention to it. The sound of doors closing in a car is created by engineers who make sure that it becomes “true”, that is, a solid pop without bouncing and other unpleasant noises. Specialists in psychoacoustics are trying to achieve this. The most successful result will be a closing door that emits a muffled bang, instilling confidence in the owner of the car, engineers believe. For this, materials are used that absorb unnecessary sounds.

Psychoacoustics studies show that high pitched sounds give people the impression of poor build quality, so the sound of closing a door should be as low as possible. In addition, the developers are carefully engaged in the selection of door seals, which also help to avoid chatter when closing and significantly soften the door contact with the body. Each company has its own kind of “sound engineer” involved in the development of sound-absorbing compounds that are applied to the inner surface of the door panel. Engineers are also working on the design of the door lock to avoid clanging when closing, or adding additional dampers.
