“…In daycare centers and schools, children's voices produce considerable levels of noise; the equivalent noise levels (Leq) measured over 8 hours were 80.1 dB (A) near the teachers' ears and 70.87 dB (A) in the classroom. The Lmax was 112.55 dB (A) near the teachers' ears and 103.77 dB (A) in the classroom 7 .…”

Summary Aim: To evaluate the sound pressure level to which preschool students are exposed. Method: This was a prospective, quantitative, nonexperimental, and descriptive study. To achieve the aim of the study we used an audio dosimeter. The sound pressure level (SPL) measurements were obtained for 2 age based classrooms. Preschool I and II. The measurements were obtained over 4 days in 8-hour sessions, totaling 1920 minutes. Results: Compared with established standards, the SPL measured ranged from 40.6 dB (A) to 105.8 dB (A). The frequency spectrum of the SPL was concentrated in the frequency range between 500 Hz and 4000 Hz. The older children produced higher SPLs than the younger ones, and the levels varied according to the activity performed. Painting and writing were the quietest activities, while free activities period and games were the noisiest. Conclusion: The SPLs measured at the preschool were higher and exceeded the maximum permitted level according to the reference standards. Therefore, the implementation of actions that aim to minimize the negative impact of noise in this environment is essential.

“…Existing means to reduce the physical strain experienced as a result of work-related factors and improve the working posture in this occupation have yet to be evaluated and validated. In addition to the physical stress levels, various studies indicate that preschool teachers are also exposed to high psychological stress levels (Eysel-Gosepath et al 2010;Rudow 2004). As complaints regarding excessive stress in the preschool workplace are being increasingly reported (Darius et al 2013), this is a current and key topic that will only become exacerbated with time as the number of children entering preschool increases (Darius et al 2013;Grant, Habes, and Tepper 1995).…”

The comparative analysis of postural and biomechanical parameters of preschool teachers pre- and post-intervention within the ErgoKiTa study

The ErgoKiTa study aimed to determine the musculoskeletal strain of preschool teachers and to identify and evaluate suitable prevention measures to reduce this strain. A comprehensive work analysis using objective and subjective methods was performed to determine the present work situation in preschools in Germany, and the results were used to derive suitable intervention measures. The musculoskeletal strain was determined by means of a comprehensive analysis of postures, forces and movements using the CUELA system and calculated as cumulative shift workloads. The intervention measures were evaluated in a pre- and post-intervention assessment for 12 participants. Significant alterations in the duration of postures were determined, specifically for the daily duration of knee-straining postures as well as the degree of trunk flexion between 60° and 90°, which were reduced from 8.4 to 3.1% and from 3.7 to 2.4%, respectively, following the intervention. Practitioner Summary: Research has shown that preschool teachers are at risk of developing musculoskeletal disorders. The effects of a situation-orientated and behaviour-orientated intervention approach were assessed with regard to awkward working postures. Significant alterations in the duration of postures following the intervention were found, specifically for knee-straining postures.

“…Eysel-Gosepath et al reported that annoyance in preschool is dependent on several additional parameters. The stress level is, for example, less for older teachers and full-time employees, which indicates that there is a subjective rating [ 17 ]. The study of Sjodin et al pointed out that there is no significant correlation between the subjective noise annoyance and the objective noise measurement [ 8 ].…”

“…Despite the fact that most average L eq8h are under the threshold of hearing impairment, teachers often complain of tinnitus or acute hearing loss [ 15 , 20 ]. The peak values of individual measurements in nursery schools were up to 113–117 dB (A)[ 17 ] and occurred particularly in free playing sections [ 17 , 21 ]. Peak values of more than 130 dB (A) may cause an acute acoustic trauma.…”

Background: Although noise is one of the leading work-related health risk factors for teachers, many nursery schools lack sufficient noise reduction measures. Methods: This intervention study evaluated the noise exposure of nursery school teachers when dropping DUPLO toy bricks into storage cases. Sound analyses of the impact included assessment of the maximum sound pressure level (LAFmax) as well as frequency analyses with 1/3 octave band filter. For the purpose of standardization, a customized gadget was developed. Recordings were performed in 11 cases of different materials and designs to assess the impact on sound level reduction. Thereby, the acoustic effects of three damping materials (foam rubber, carpet, and PU-foam) were investigated. Results: The lowest LAFmax was measured in cases consisting of “metal grid” (90.71 dB) or of a woven willow “basket” (91.61 dB), whereas a case of “aluminium” (103.34 dB) generated the highest impact LAFmax. The frequency analyses determined especially low LAFmax in the frequency bands between 80 and 2500 Hz in cases designs “metal grid” and “basket”. The insertion of PU-foam achieved the most significant attenuation of LAFmax (−13.88 dB) and, in the frequency analyses, the best sound damping. Conclusion: The dropping of DUPLO bricks in cases contributes to the high noise level in nursery schools, but measured LAFmax show no evidence for the danger of acute hearing loss. However, continuous exposure may lead to functional impairment of the hair cells and trigger stress reactions. We recommend noise reduction by utilizing cases of woven “basket” with an insert of PU-foam.
