Acoustical performance is an important consideration in the design of classrooms.  Research indicates that levels of background noise and reverberation, little noticed by adults, adversely affect learning environments for young children, who require optimal conditions for hearing and comprehension.  Poor classroom acoustics are an additional educational barrier for children who have hearing loss and those who use cochlear implants, since assistive technologies amplify both wanted and unwanted sound.  Children who have temporary hearing loss, who may comprise up to 15% of the school age population according to the Centers for Disease Control, are also significantly affected, as are children who have speech impairments or learning disabilities.  Kids whose home language is different than the teaching language are also at additional risk of educational delay and failure.

International Standards and Guidelines

Countries that have implemented standards and guidelines for classroom acoustics include:

Acoustics and Sustainable/Green Design

Building design features that promote sustainability are also effective in achieving good acoustics.  LEED objectives include criteria for classroom acoustics, and the Massachusetts Collaborative for High Performance Schools Standard offers credit for meeting the ANSI/ASA S12.60-2002 standard.
