Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that prolonged exposure to environmental noise causes tinnitus?

Partly. One small occupational cohort of Nigerian generator technicians found prolonged noise exposure raised the odds of tinnitus, and a review notes tinnitus can result from noise exposure; however, a two-month mouse noise-exposure study found no tinnitus, and a systematic review of non-occupational noise identified no qualifying studies. The evidence covers only parts of the claim and points both ways.
