The diploma thesis examines the occurrence of noise during educational work in kindergarten, and its impact on preschool teachers' hearing. The study involved 5 groups of children from the 1st age bracket and 5 groups of children from the 2nd age bracket, and 15 teachers at the kindergarten Vrtec Kočevje. The sample was used to examine the noise level that occurs during various activities in groups of the 1st and 2nd age bracket. The noise level was measured during different activities – routine activities (breakfast, snack, lunch, rest), guided activities, and the children's spontaneous play, namely during the first week in groups of the 1st age bracket, and during the following week in groups of the 2nd age bracket. The study also aimed to determine what teachers think about noise during educational work in kindergarten, and their hearing was tested. The teachers' opinions were obtained by means of a survey questionnaire, while the hearing tests were carried out using the Fowler-Sabine mobile application.
The analysis has determined that the highest noise level in groups of children from the 1st age bracket occurs during guided activities and amounts to 81.20 dB(A), while in groups of children from the 2nd age bracket it occurs during the children's spontaneous play and amounts to 89.80 dB(A). The noise level measurements have also shown that children from the 2nd age bracket groups are louder during most activities than the children from the 1st age bracket groups. It has also been established that there are no major deviations in hearing deterioration in most preschool teachers based on their length of service and age; most of them have a hearing threshold of up to 13 dB, which means that they have normal hearing according to the hearing loss classification.
