Sudden sensorineural hearing loss (SSHL), commonly known as sudden deafness, occurs as an unexplained, rapid loss of hearing—usually in one ear—either at once or over several days. It should be considered a medical emergency. Anyone who experiences SSHL should visit a doctor immediately.

The human ear is the envy of even the most sophisticated acoustic engineer.
