Abstract [en]

Objective: The aim of the study was to investigate the noise exposure for different technical officials during a major badminton tournament.

Methods: Individual noise exposure for technical officials was measured during the 23rd BWF World Championship, 2017 in Glasgow, Scotland during all days of the tournament.

Results: Umpires and on-court-doctors had equivalent noise exposure, when working longer shifts, that exceeded the exposure limit according to the EU 2003/10/EC noise directive. Exposure limits regarding impulse sound was also exceeded during several work shifts during the tournament.

Conclusions: Technical officials are exposed to noise levels that exceed current occupational health leg-islation within the EU, and may therefore be at risk of developing hearing related disorders. It is of high importance for the organizers of sports events to reduce the noise exposure for the technical officials by scheduling shorter work periods, but also by providing individual hearing protectors.

Abstract [en]

The study included 12 preschool departments, with two teachers in six departments characterised by high levels of stress and burnout and two teachers in six departments characterised by low levels of stress and burnout. A total of 24 females with a mean age of 43.5 years participated in the study. The teachers rated stress, fatigue, work demands and work burnout using different questionnaires. Cortisol samples were collected at wake up, one hour after wake up, at 11:00 am and at 09:00 pm. An observation study was conducted to create an overview of the communication patterns between the children and the personnel during different time periods. Significant differences between the two groups of teachers were observed regarding the organisation of the work and family situation. The high-stress teachers had more communications from colleagues than low-stress teachers, spent more time on pedagogical planning and had young children at home. These results support the view that the organisation is a central factor regarding stress experienced by preschool teachers.

Abstract [en]

Studies have shown that preschool teachers often report having a troublesome working environment in terms of high noise levels. Noise annoyance is often reported from employees working under poor acoustical conditions. The aim of the study was to investigate whether there is an association between rated noise annoyance and actual noise exposure for Swedish preschool teachers. The study included 90 preschool teachers in Sweden. The average equivalent noise exposure was about 71 dBA and the average rated noise annoyance was about 65 on a 0-100mm scale. Rated noise annoyance was weakly associated with the sound exposure during a work week in the preschool (r = 0,23, P = 0,07). Analysis for differences in noise annoyance ratings between preschool teachers with different individual characteristics (hearing impairment, tinnitus, age, gender) revealed no statistical significant differences. However; teachers that worry about their hearing (t = -4,66, df = 86, P < 0,05) and teachers with a high degree of burnout (t = -2,88, df = 86, P < 0,05) reported more noise annoyance. Other factors besides noise levels need to be investigated to better explain what affects differences in rated noise annoyance at work among preschool teachers in Sweden.

Abstract [en]

During recent years in Sweden the number of complaints regarding hearing related disorders from employees working in the preschool (kindergarten) has increased. It is often assumed that the size of the child group is the crucial factor associated with the high noise levels. However, the association between the noise levels and the size of the child group is not fully understood. Further, it is likely that the gender balance and the age of the children have an effect on the noise levels in the preschools.

 

The aim of the study was to investigate the association between noise in the preschool and the constitution of the child group in terms of number of children, gender balance and the children’s age.

 

Noise levels were recorded at 34 preschool sites in Sweden using stationary sound level meters with an external microphone mounted in the ceiling in the dining room and the play halls at each site. Sound level measurements were carried out during 2-3 days in each room during the entire workday. Data regarding the constitution of the child group for every day was collected at the end of the week from the enrollment list.

Abstract [en]

Purpose

The aim of the study was to analyze the exposure effects of different types of noise measures carried out at preschools. The project was carried out as an intervention study.

Methods

The investigation included 89 employees at 17 preschools in the northern part of Sweden. Individual noise recordings and recordings in dining rooms and play halls were made at two departments in each preschool. The adverse effects on the employees were analyzed with validated questionnaires and saliva cortisol samples. Evaluations were made before and one year after the first measurement. Between the two measurements, measures had been taken to improve the sound environments at the preschools.

Results

The effects of the measures varied at lot, both with respect to the sound environments and health. Regarding acoustical measures, significant changes were seen for some of the variables analyzed. For most of the tested effects, the changes however were very small and non-significant. The effects of organizational measures on the objective and subjective noise values were in overall less pronounced.

Conclusion

Acoustical measures improved the subjectively rated sound environment more than organizational measures. This may be due to the high work effort needed to implement organizational measures. Even though the sound level was not lower, the personnel experienced improvements of the sound environment.

Abstract [en]

Use of noise dosimeter recordings in low sound level environments is often problematic due to the voice contribution from the carrier. The aim of the study was to find a microphone position with low speech contribution while still providing an accurate sound level recording. An experiment with different microphone positions was conducted in a low sound reverberation room. Two types of noise dosimeters were used (Brüel & Kjaer 4445 and Larson Davis Spark 706-Atex). In repeated measurements the carrier was instructed to read a text chapter during 60 seconds and at a speech of level about 60 dB(A), acquired by practice, with different background noise and noise levels. White noise and preschool noise was used at sound levels 50, 60, 70 and 80 dB(A). The voice contribution to the background noise level was then measured. Three microphone positions were tested; on the shoulder, above the ear and on the back of the head. The position with the microphone placed behind the head of the carrier had the lowest speech contribution, less than 2 dB(A) to the background noise at 70 dB(A). This compared to positions right above the ear 6 dB(A and on the shoulder 12 dB(A).

Abstract [en]

The aim of the study was to analyze the presence of stress-related health problems among preschool employees and the way in which these reactions are related to noise and other work parameters. The investigation included 101 employees at 17 preschools in Umeå County, located in northern Sweden. Individual noise recordings and recordings in dining rooms and play halls were made at two departments from each preschool. The adverse effects on the employees were analyzed by use of different validated questionnaires and by saliva cortisol samples. Stress and energy output were pronounced among the employees, and about 30% of the staff experienced strong burnout syndromes. Mental recovery after work was low, indicated by remaining high levels of stress after work. The burnout symptoms were associated with reduced sleep quality and morning sleepiness. Cortisol levels supported the conclusion about pronounced daily stress levels of the preschool employees.
