Pilot testing of S.I.R.E.N-Safety Instruction to Reduce Exposure of Noise and hearing loss: Preliminary findings of firefighters' feedback

Background: Noise-induced hearing loss (NIHL) is a significant occupational injury for firefighters (FFs) who are exposed to intermittent noise on the job. Reducing NIHL among FFs is important to reduce morbidity and mortality as well as improve quality of life and work safety. The purpose of this study is to evaluate the usability of a theory-driven, tailored, and internet-based hearing protection intervention called S.I.R.E.N that was designed to prevent NIHL. Methods: The SIREN program was developed by a multidisciplinary team from industrial hygiene, occupational medicine and nursing, hearing science, and computer engineering. A pilot field test was conducted with a small group of FFs (N=14, mean age= 43years, 100% male) in the San Francisco Bay Area and users' feedback were summarized by qualitative and quantative methods. Results:The majority (93%) reported the program was well organized and easy to use (86%). About 80% said logging on to the SIREN program was easy and 86% reported no problem using the computer. About 72% reported their computer/internet skills were above average and liked getting the training by computer. About 86% indicated that the training was effective. Several positive features reported by the participants included logical progression, interesting and motivating multimedia program, and easy to use. Conclusion: This pilot test confirmed that the internet-based SIREN program's usefulness and smooth operation for FFs without any major technical and logistical issues. Based on the favorable feedback and successful field testing, a full scale implementation of the SIREN is planned.
