The Impact of Monthly Exposure to Loud Noise During Leisure Time on Risk of Tinnitus

https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/2533660
"The prevalence of tinnitus for those with monthly exposure to loud noise in leisure time was 17.1% compared with 7.4% for those without such exposure (odds ratio, 2.6; 95% CI, 2.3-2.9)."
So this means that the risk of T is 2.31 (17.1/7.4) times higher when you experience monthly exposure to loud noise during your leisure time.

"In addition to tinnitus variables, respondents were queried on noise exposure at work and during recreational time. When surveying work noise exposure, interviewers defined loud environments as those in which one must speak in a raised voice to be heard. In an effort to maintain uniformity, several particular recreational time activities, including the use of gardening and workshop tools, machinery, motorcycles and other motor engines, loud household appliances, MP3 players, and concert attendance, among others, were queried."

These results are based on the "analysis of responses from 75 764 US adults."
