New report shows that European schools neglect their sound environment

A new report finds that far too many European schools neglect their sound environment. Noise harms children’s learning and health and creates inequalities for students with special needs. More schools should regularly measure noise levels and design according to acoustic standards and recommendations in order to provide optimal learning environments, that have the added benefit […]

New research shows that a lower reverberation time helps children cope with multi-talker listening situations

How children make sense of the complex signals they hear in the classroom depends partly on their hearing and cognitive abilities. But newly published research shows more about the important part played by the acoustic environment in this process; specifically, the role of reverberation time.  The ability to make sense of what you are hearing […]
