Equalization
Equalization (medicine)
Equalization (pronounced: ee-kwuh-luh-zey-shuhn) is a term used in various fields of medicine, particularly in audiology and barotrauma. It refers to the process of balancing pressure in different parts of the body, such as the ear or sinus cavities, to prevent discomfort or damage.
Etymology
The term 'equalization' originates from the Latin word 'aequalis', meaning 'equal', and the suffix '-ization', which denotes an action or process. In the medical context, it refers to the process of making pressures equal.
In Audiology
In audiology, equalization refers to the process of adjusting the balance between frequency components within an electronic signal. This is often done to compensate for the unequal frequency response of the human ear, allowing for a more accurate representation of sound.
In Barotrauma
In the context of barotrauma, equalization is the process of balancing the pressure in the ear or sinus cavities with the external pressure. This is often necessary when diving or flying, as rapid changes in external pressure can cause discomfort or damage if not equalized.
