[en] Teachers and students suffer from the impact of noisy classrooms. This is due to poor sound isolation, traffic and noise generated by electronic data processors, HVAC (Heating, Ventilation and Air Conditioning) interference and reverberation levels. For teachers, this resulted in increased vocal loading and fatigue, frequently leading to vocal issues. Furthermore, poor acoustic conditions influence children language acquisition process, sometimes leading to impaired concentration, behavioural disorders, and attention deficit. The problem is more enhanced in children with hearing impairment (temporary or permanent) or with other disabilities. Lack of information and normative data on the aspects of building design and classroom acoustics have prompted this review, which comprises of sources originated from Canada, France and Belgium.
