That is normal: The Eustachian tube is a tube that links the nasopharynx (throat) to the middle ear. Under normal circumstances, the human Eustachian tube is closed, but it can open to let a small amount of air through to prevent damage by equalizing pressure between the middle ear and the atmosphere. When you build up pressure in the mouth, it can also force air into the middle ear, causing the crackling sound
