In recent years sensory history has emerged as a research topic of growing interest to historians and has been accompanied by a call to incorporate the senses into our understanding of the past. Under modernity, social direction and control were built into the infrastructure of modern life as specialist institutions emerged and multiplied in the urban landscape; institutions which were designed to discipline, control and shape urban bodies--the prison, the workhouse, the asylum, the reformatory, the children's home and the school. This paper focuses on one of these sites of childhood control: the school. Historians of education and childhood have to date paid little attention to the sensory worlds of schooling and childhood. This study focuses on one sense--hearing. Hearing, sound and aurality have been shown to be deeply implicated in modernity's daily elaboration. The study explores the sounds of modern schooling; the culture of listening in modern schools; the materiality of the modern school "soundscape"; and the influence of architectural acoustics on the culture of listening. In doing so, the study addresses the problems, sources and methodologies involved in writing a history of the hearing school. (Contains 65 footnotes and 1 figure.)
