Studies in other countries have shown that the actual noise levels in classrooms can exceed WHO requirements. Pupils exposed to chronic noise seem to develop inferior reading skills. Chronic exposure to noise can result in reduced motivation for taking on new challenges and solve problems. Acute noise can serve as a distracter, reducing the ability to concentrate. Both acute and chronic noise seems to have and adverse effect on long-term memory. A high noise level in the classroom results in teachers and pupils having to strain their voices in order to be heard. In some cases this can lead to voice disorders.
