Non-usage of earplugs, alcohol and drug use, and the male sex are associated with a temporary threshold shift after music exposure at outdoor music festivals, a new study found. (JAMA Otolaryngol Head Neck Surg. 2018;144[6]:490.) This prospective analysis gathered data from a randomized, single-blind clinical trial conducted at a 4.5-hour outdoor music festival involving 51 volunteers in Amsterdam, the Netherlands. Mean threshold change across 3.0 and 4.0 kHz was 5.4 (5.7) dB for the right ear and 4.0 (6.1) dB for the left ear. Earplug use, quantity of alcohol use, drug use, and male sex were independently associated with hearing loss, with earplug use being the most important factor, which had an absolute difference of -6.0 dB in the left ear and -6.4 dB in the right ear. Unprotected participants reported significantly worse subjective hearing performance and tinnitus after the festival visit than did participants who used earplugs. The study authors said physicians should consider these factors to raise awareness about the combined risk of attending music festivals without using earplugs while consuming alcohol and/or drugs.
