Systematic Review on Speech Intelligibility and Classroom Acoustics in Elementary Schools
What is it about?
This systematic review and meta-analysis aimed to characterize the relationship between intelligibility of speech and room acoustics in real elementary classrooms based on the available evidence. The results underlined the negative effect of poor classroom acoustics, due to long reverberation times and high background noise levels on elementary students’ performances, highlighting the need for a good classroom acoustic design to support children's academic success.
Why is it important?
This research provided a first analysis that can be generalized to all elementary school children, helping direct future projects to minimize the effect of poor acoustics on children’s academic success.
