Abstract
It has been known for many years that poor acoustic conditions in classrooms leading to high noise
levels and poor speech intelligibility cause annoyance to pupils and teachers and affect the
academic performance of pupils. Much of the previous research concerning the impact of noise and
poor acoustics on pupils has involved children in primary schools, with fewer studies related to
pupils of secondary school age. Furthermore, the majority of previous studies in schools have
examined the impact of environmental noise, particularly aircraft noise, on children. The aim of the
study described here was to examine the effects of typical levels of classroom noise on secondary
school pupils, and to attempt to identify the threshold level at which adverse impacts might occur.
A survey of acoustic conditions in secondary schools in England1 was accompanied by
questionnaire surveys of pupils to ascertain levels of annoyance caused by noise, and their
perceptions of its interference with their ability to hear and understand their teachers2
. In addition,
students were tested in numeracy, mathematical reasoning, memory and reading comprehension in
different levels of classroom noise. This paper describes the results of reading comprehension tests
undertaken by nearly 1000 pupils aged between 11 and 16 years while they were exposed to typical
classroom noise at different levels
