Configuration of Hearing Loss
The extent of hearing loss at various frequencies is called the configuration of hearing loss for an individual. For example, a hearing loss that occurs at high frequencies would be considered a "high-frequency loss". Its configuration would show insufficient hearing at the higher frequencies and adequate or acceptable hearing at the lower frequencies. The exact opposite can be said for someone experiencing poor hearing at lower frequencies. Some configurations are flat, indicating similar hearing loss for low and high tones.
Other Ways to Describe Hearing Loss
Bilateral versus unilateral. Bilateral hearing loss refers to impairment in both ears. Unilateral hearing loss refers to just one affected ear.
Symmetrical versus asymmetrical. Symmetrical hearing loss refers to the same or very similar degree and configuration of hearing loss in each ear. An asymmetrical hearing loss refers to a variation in the degree and configuration of loss in each ear.
Progressive versus sudden hearing loss. Progressive hearing loss refers to a continuous reduction in hearing ability. A sudden hearing loss refers to a rapid acute onset. It is recommended to receive immediate medical attention if this occurs.
Fluctuating versus stable hearing loss. Fluctuating hearing loss is generally an indication of conductive hearing loss caused by ear infection and fluid residing in the middle ear, but could also exist as other conditions.
