How loud is a door shutting?

The loudness of a door shutting can vary widely depending on several factors, such as the type of door, the material it's made from, and how forcefully it is closed. Generally, the sound level can range from about 50 to 80 decibels. A typical interior door might produce a sound around 60 decibels, while a solid exterior door could reach 70 decibels or more. For comparison, 60 decibels is similar to normal conversation, while 70 decibels is akin to a vacuum cleaner.
