Many overseas investigations reveal that the acoustical environment in classrooms is crucial to
students' speech perception, academic performance, attention and participation in class. The
purpose of this investigation is to provide a preliminary study of the noise levels in Hong Kong
primary school classrooms. Apart from the ambient noise level, its relationship with the intensity
of speech levels of both teachers and students was examined in 47 classrooms. Moreover, the
presence of acoustical treatments for noise reduction was documented in each classroom. Results
revealed that: 1) the mean occupied noise level was 60.74 dB (A); 2) the mean unamplified and
amplified speech-to-noise ratio of teachers was 13.53 dB and 18.45 dB respectively while the
mean unamplified speech-to-noise ratio of students was 4.13 dB; 3) most of the classrooms
exhibited insufficient acoustical treatments for noise reduction. Results revealed that the listening
environment in many Hong Kong primary schools was not favorable for optimal classroom
learning. The resulting audiological implications, and recommendations for improving the
acoustical environment in classrooms, were discussed.
