Glue ear, a condition resulting in intermittent hearing loss in young children, affects about 80% of young children under seven years old. About 60% of children will spend a third of their time unable to hear within normal thresholds. Teachers are unlikely to consider the sound quality in classrooms. In my research young people provided suggestions to help them hear, identifying the benefits of using their insight in improving the hearing environment. This article identifies five aspects from the literature which impact the hearing environment in classrooms. The focus is on practical low-cost actions that teachers can implement in their classrooms, thus reducing stress levels in students and teachers.
