Noise in schools can have negative effect on the teaching environment and speech perception. The national Child Environmental Health Surveys (BMHE) conducted in 2003 and 2011 studied how 12-year olds experience their sound environment in school. Results showed that the number of pupils that experience annoyance from noise increased from 2003 to 2011.Aim: The aim of this study was to study how 12-year olds perceive their sound environment in school.Methodology and material: A quantitative questionnaire survey was conducted in the sixth grade at two schools. The questionnaire used included questions from BMHE and self-produced questions. Sixtynine students answered the questionnaire.Results: Over 50 % of the respondents experience annoyance from noise in school several times a week. Noise from other children, scraping from chairs and ventilator noise are then main sources of annoyance. The same source of sound causes different degrees of annoyance depending on the location. Strong correlation was found between the degree of annoyance and how often the respondents report being annoyed by the same sound source. A majority experienced negative effects on learning and cognitive processes and used strategies to avoid the noise in school.Conclusion: Our results correspond well with those from previous studies done, but in comparision with national study BMHE 2003 and 2011 the perceived annoyance seems to have increased. Preventive measures against noise in schools are important for a good learning environment and the students performance.
