Which term is used to describe hearing loss that occurs gradually over time?

The term that describes hearing loss that occurs gradually over time is "progressive." This type of hearing loss typically develops slowly and can often go unnoticed in the early stages as individuals may adapt their listening habits without realizing that their hearing is deteriorating. Progressive hearing loss can be associated with various factors, including age-related changes, long-term exposure to loud noises, or certain medical conditions.

In contrast, "sudden" refers to hearing loss that occurs quickly, often over a matter of hours or days, which is significantly different from the gradual nature of progressive loss. "Acute" generally indicates a severe but short-term occurrence, while "temporary" suggests a reversible condition that is not permanent, both of which do not align with the gradual decline associated with progressive hearing loss. Understanding these distinctions is vital for identifying the nature and potential treatment of hearing impairments.
