What can 35 years and over 700,000 measurements tell us about noise exposure in the mining industry?

Roberts, B. et al. (2017) International Journal of Audiology. 56(Supp.1) pp. 4-12


Objective: To analyse over 700,000 cross-sectional measurements from the Mine Safety and Health Administration (MHSA) and develop statistical models to predict noise exposure for a worker.

Conclusion: Overall noise levels in mines have been decreasing. However, this decrease has not been uniform across all mining sectors. The exposure predictions from the model will be useful to help predict hearing loss in workers in the mining industry.

Working with Randolph-Sheppard Entrepreneurs Who Are Deafblind: A Qualitative Analysis

Hierholzer, A.C. & Bybee, J. (2017) Journal of Visual Impairment & Blindness. 111(1) pp. 61-71


Introduction: The purpose of the study was to explore challenges facing deafblind entrepreneurs and the staff who work with them through the Randolph-Sheppard Business Enterprise Program.

Discussion: Entrepreneurs and staff agreed that many challenges relating to deafblindness can be overcome with creativity and determination. One important approach for improving communication is proactively informing customers about the entrepreneur’s deafblindness and describing communication strategies. Further research to determine the extent of hearing loss among entrepreneurs in the Randolph-Sheppard program would be beneficial. Implications for practitioners: Individuals with deafblindness have demonstrated the ability to take part in the workplace, but challenges remain. Staff who work with these entrepreneurs need to help them address their unique communication needs in a proactive, positive manner.

Objective: The present study reports on the application of a Swedish translation of the audiologist occupational stress questionnaire (AOSQ) on audiologists working in Sweden. The relations between AOSQ scores and perceived effort, perceived rewards, coping strategies at work, demographic variables such as salary, education length, practise length, and practice type were tested.

Design: A cross-sectional e-mail survey using the AOSQ, effort-reward imbalance questionnaire, and demographic questions.

Study sample: Four-hundred and four Swedish licensed audiologists working with clients.

Results: The Swedish AOSQ translation demonstrated high inter-item correlations and high internal consistency. Several stress factors were identified: time spent at work, accountability, leadership at the workplace, paperwork and practice demands, equipment and clinical protocols, own health concerns, and job control. The outcome on the complete AOSQ questionnaire was related to perceived effort, perceived rewards, coping strategies at work, and age.

Conclusions: The Swedish AOSQ translation seems to provide a valid measure of occupational stress among audiologists.
