The management and control of modern automated productions evidence the elevated role of the auditory system as one of the distant sensor communication systems. The present study informs about the auditory adaptation and fatigue at the end of the working shift of 385 operators at control boards in "Kremikovtzi" State Company. The results of the monitoring of the dynamic changes show significant changes, expressed in aggravation of the auditory fatigue manifestation by moderate to significant disturbance of the adaptation-recovery processes. The analysis established a significant positive correlation between the changes in auditory fatigue and the duration of service. The frequencies of the speech range are preserved for a long time. The elevated auditory fatigue is observed in the injured hearing band 4,000 Hz, followed by 6,000 Hz and continuous dissemination to the middle frequencies of the speech band-2,000 and 1,000 Hz. The results of the study of the adaptation-recovery processes are characterised by statistically significant reliability, single direction and reproducibility and can be applied as informative criteria for assessment of the auditory health risk.

Revista Brasileira de Enfermagem 2018To measure the response time of health professionals before sound alarm activation and the implications for patient safety. (Observational Study)
Observational Study
OBJECTIVE
To measure the response time of health professionals before sound alarm activation and the implications for patient safety.
METHOD
This is a quantitative and observational research conducted in an Adult Intensive Care Unit of a teaching hospital. Three researchers conducted non-participant observations for seven hours. Data collection occurred simultaneously in 20 beds during the morning shift. When listening the alarm activation, the researchers turned on the stopwatches and recorded the motive, the response time and the professional conduct. During collection, the unit had 90% of beds occupied and teams were complete.
RESULT
We verified that from the 103 equipment activated, 66.03% of alarms fatigued. Nursing was the professional category that most provided care (31.06%) and the multi-parameter monitor was the device that alarmed the most (66.09%).
CONCLUSION
Results corroborate the absence or delay of the response of teams, suggesting that relevant alarms might have been underestimated, compromising patient safety.

OBJECTIVE
There is a lack of research on effects of occupational noise exposure in traditionally female-dominated workplaces. Therefore, the aim of this study was to assess risk of noise-induced hearing-related symptoms among obstetrics personnel.
DESIGN
A cross-sectional study was performed at an obstetric ward in Sweden including a questionnaire among all employees and sound level measurements in 61 work shifts at the same ward.
PARTICIPANTS
115 female employees responded to a questionnaire (72% of all 160 employees invited).
MAIN OUTCOME MEASURES
Self-reported hearing-related symptoms in relation to calculated occupational noise exposure dose and measured sound levels.
RESULTS
Sound levels exceeded the 80 dB LAeq limit for protection of hearing in 46% of the measured work shifts. One or more hearing-related symptoms were reported by 55% of the personnel. In logistic regression models, a significant association was found between occupational noise exposure dose and tinnitus (OR=1.04, 95% CI 1.00 to 1.09) and sound-induced auditory fatigue (OR=1.04, 95% CI 1.00 to 1.07). Work-related stress and noise annoyance at work were reported by almost half of the personnel. Sound-induced auditory fatigue was associated with work-related stress and noise annoyance at work, although stress slightly missed significance in a multivariable model. No significant interactions were found.
CONCLUSIONS
This study presents new results showing that obstetrics personnel are at risk of noise-induced hearing-related symptoms. Current exposure levels at the workplace are high and occupational noise exposure dose has significant effects on tinnitus and sound-induced auditory fatigue among the personnel. These results indicate that preventative action regarding noise exposure is required in obstetrics care and that risk assessments may be needed in previously unstudied non-industrial communication-intense sound environments.

Comparative Study
The present study was designed to explore psychoacoustic correlates of susceptibility to auditory fatigue. Fifty-six normal-hearing subjects were given two monaural auditory fatigue tests. The high-frequency test consisted of a 3-min exposure to a 110 dB SPL, 2 kHz pure tone, with temporary threshold shift (TTS) measured at 4 kHz. The low-frequency test consisted of a 3-min exposure to a 115 dB SPL, 500 Hz pure tone, with TTS measured at 1 kHz. Amount of TTS and TTS recovery time were compared with performance on a test battery consisting of: (1) masking level differences; (2) brief-tone audiometry; (3) speech discrimination in noise; and (4) the threshold of octave masking test. A small negative correlation was found between amount of TTS and results of the threshold of octave masking test and the results of brief-tone audiometry. Subjects with larger amounts of TTS tended to have lower thresholds of octave masking and flattened threshold-duration functions.

The purpose of this article is to describe the impact of an evidence-based alarm management strategy on patient safety. An alarm management program reduced alarms up to 30%. Evaluation of patients on continuous cardiac monitoring showed a 3.5% decrease in census. This alarm management strategy has the potential to save $136 500 and 841 hours of registered nurses' time per year. No patient harm occurred during the 2-year project.
