A Bit About Bostons. A cross between the English bulldog and the white English terrier, the Boston originated in Boston, Massachusetts in the late 19th century. Not larger than 25 pounds, the dog is muscular, alert and intelligent, and has an easygoing personality. That said, heart disease is the leading cause of death in this breed.
Many children are born deaf because of a genetic reason. Deafness can be passed down in families even though there appears to be no family history of deafness. Sometimes the gene involved may cause additional disabilities or health problems. Deafness can also be caused by complications during pregnancy. Illnesses such as rubella, cytomegalovirus (CMV), toxoplasmosis and herpes can cause a child to be born deaf.
This is why your ears pop. Sometimes people suffering from ETD get crackling noises in their ears or deafness. The deafness is usually temporary and is as a result of the normal flexible ear drum, or tympanic membrane, becoming stiff as a result of the increased pressure behind it. The ear drum is therefore unable to move when a sound wave hits it and so the sound is muffled when it is heard. The crackling is due to the mucus moving within the middle ear. It is the blockage of the Eustachian tube that causes pain in the ears when flying as the changes in air pressure make it difficult for the pressure across the ear drum to equalise. This causes the ear drum to be stretched, which is painful.
