There is a considerable amount of research documenting the effects of noise on children. The effects are largely negative. Chronic exposure to noise has been shown to be harmful to children of various ages. It can have especially detrimental effects on younger children when language and discrimination skills are forming. Sometimes major noise sources are not in the control of teachers or designers. However, as this study documents, sometimes the noise source is the design of the spaces. Designers should keep in mind the use of the spaces they are creating. In child care centers, spaces must allow for the fact that children need to make noise but the subsequent noise levels should not be harmful to them or others in the center.
