We administered the Dangerous Decibels hearing-health intervention to nightclub staff to test its efficacy. In a single group, repeated measures were taken before training, a week after training and at 3£¿months after training. A nightclub in the city of Auckland, New Zealand. We delivered training to 20 people who work in nightclubs: bar staff, disc jockeys (DJs), security staff and police. We assessed supports and barriers towards hearing-health behaviour, knowledge, attitudes and self-reported behaviour at the three time points. The ratio of supports to barriers for good hearing-health behaviour improved 1£¿week after training and continued to improve at 3£¿months. Participants¡¯ knowledge increased after training and was maintained 3£¿months later. Attitudes and self-reported behaviour did not change. The continued improvement in supports-to-barriers ratio at 3£¿months post-training has not been observed previously and may reflect a change in participants¡¯ thinking as a result of the intervention. The lack of change in self-reported behaviour implies that the effect of acculturation to loud music in nightclubs was not wholly overcome %K Dangerous Decibels %K ecological model %K noise %K New Zealand %K nightclubs %K noise-induced hearing loss %K prevention %U https://journals.sagepub.com/doi/full/10.1177/0017896918800516
