Classroom acoustics has significant effects on the teaching quality, especially in primary and secondary schools. The acoustic environment of 30 classrooms in 15 primary and secondary schools in Southwest China were measured, meanwhile 1417 students and 342 teachers participated in the questionnaire survey. The average background noise levels in unoccupied classrooms, without fan operation, of Sichuan and Guizhou province are 50.96 dBA and 52.7 dBA respectively, whereas the average reverberation time of Sichuan and Guizhou are 1.26s and 1.29s. 31.5% of interviewed teachers and 26.5% of students agree that the most important environmental factor to be improved in classrooms is acoustic environment. 29.8%, 21.7% and 29.6% of interviewed students believe that noise in classroom has very serious or serious impact on their memorable learning, interpretive learning and creative learning. 68.81% of the students consider noise may lead to inattention, while 60.9% of the students provide that noise could influence their learning efficiency. In terms of noise improvement strategies in the schools, more green areas are selected by more than half of the students, followed by noise barriers (44.4%) and soundproof windows (44.3%).
