Voice handicap prevalence among healthcare workers in China and Indonesia
This study investigated the prevalence of voice disorders among healthcare workers in China and Indonesia. A questionnaire was administered to 721 healthcare workers, with 411 from China and 310 from Indonesia during the COVID-19 pandemic. The questionnaire assessed vocal-related symptoms, perceived voice handicap, frequently heard noise sources, and the quality of communications. The results revealed that the most frequently reported symptoms were ‘voice tiredness’ (20.5 %) and ‘clearing the throat’ (18.3 %). Specifically, 19.4 % of Chinese healthcare workers experienced voice-related symptoms, whereas only 6.3 % of Indonesians reported such symptoms. Longer working hours and working years were significantly associated with voice-related symptoms. Furthermore, the healthcare workers in China and Indonesia both reported mild (<30) voice disorders based on the Voice Handicap Index (VHI-30). Approximately one-fourth (23.8 %) of healthcare workers in China had VHI-30 scores exceeding 30, compared to only 7 % in Indonesia. The differences in vocal-related symptoms and voice handicap between the two countries were significant. Healthcare workers with 50–60 working hours per week exhibited higher scores than those working 40–50 h per week in both countries. Additionally, communication quality and the severity of voice problems for healthcare workers in China were worse than in Indonesia during the pandemic.
期刊介绍:
Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense.
Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems.
Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
