Knowledge, attitudes, behaviors, and noise exposure of baristas

To examine the daily noise exposure of baristas working in cafes, and to measure their knowledge, attitudes, and behaviors regarding hearing conservation and perceptions of noise in their work environment. Design: Fifteen baristas from six cafes in Portland completed the Knowledge, Attitudes and Behaviors questionnaire, a sound disturbance survey, and a structured interview to document perceptions of noise in the work environment. To measure daily noise exposure, a subset of eight participants wore a personal dosimeter for three different work shifts. Study sample: A total of 11 females and four males, aged between 19 and 36 years old (mean: 26.3, SD: 4.6) recruited from independently owned cafes in the Portland metro area. Results: Dosimetry measurements revealed Leq measurements between 71 and 83 dBA, with noise doses ranging from 4% to 74%, indicating that baristas are not exposed to sound levels above the regulatory criterion. Questionnaire results indicated that baristas have low awareness about the hazards of noise, are not opposed to hearing conservation, and rarely use hearing protection when engaged in noisy activities. Conclusions: Baristas here lacked the pertinent education and motivation to commit to invaluable hearing conservation practices.
