  • Holistic solutions for acoustic comfort in day-care facilities [Elektronski vir]
    Dovjak, Mateja ...
    Room acoustics is an important factor when considering health and well-being of children and employment staff in day-care centres. Studies concluded that long reverberation times might have negative ... effects on productivity, communication and learning abilities, health and overall well - being. Especially problematic are educational facilities with a high degree of indoor noise. The main objective of the study was to define holistic solutions for acoustic comfort in day-care centres, through acoustical adaptation. A case study was performed in a playroom of a day-care centre with inappropriate room acoustics as evaluated by staff. According to the objectives of the study, we performed six steps: 1. personal communication including a survey with the users before acoustical adaptation, problem definition; 2. review of specific requirements and recommendations; 3. acoustic calculations and laboratory measurements of different materials absorption coefficient; 4. construction of prototypical acoustic elements; 5. acoustical adaptation and in-situ measurements of reverberation time; 6. communication with the users after acoustical adaptation, assessment of user satisfaction. Final prototypical absorbers were designed according to the performed steps. They were effective from acoustic, sanitary-technical and hygienic conditions that apply to the specific environment. The subjective response of the users after the adaptation was extremely positive. (PACS no. 43.50.Ba, 43.50.Jh, 43.55.Dt, 43.55.Hy)
