What does congenital hearing loss mean?

Congenital hearing loss refers to a type of hearing impairment that is present at birth, either due to genetic factors or complications during pregnancy or delivery. This condition can affect how an individual processes sound and can be varying in degree, ranging from mild to profound hearing loss. Understanding congenital hearing loss is crucial for early diagnosis and intervention, which can significantly improve communication abilities and overall quality of life.

The other options do not accurately define congenital hearing loss. Acquiring hearing loss before adulthood does not specify that the impairment exists from birth. Pseudohypacusis refers to a form of hearing loss that is not due to an actual auditory deficit but rather a behavioral or psychological component. Meniere's disease is a specific inner ear disorder that can affect balance and hearing, but it is typically not present at birth, rather it develops later in life. Thus, the choice indicating that congenital hearing loss is present at birth is the most accurate definition.
