What percent of adults have experienced tinnitus for at least 3 months?

Tinnitus, characterized by the perception of phantom sound in the ears, is a common condition affecting a substantial portion of the population. Studies have shown varying prevalence rates depending on the criteria used for defining tinnitus and the population sampled. According to a comprehensive review published in JAMA Otolaryngology-Head & Neck Surgery in 2019:

- Approximately 10-15% of adults worldwide experience tinnitus.

- About 2-3% of adults experience chronic or persistent tinnitus that lasts for at least 3 months.

It's worth noting that these figures represent an average estimate across different studies, and the prevalence of tinnitus may vary among different regions and demographic groups. Additionally, subjective perception and reporting of tinnitus can influence prevalence rates.
