Acoustics, Audibility and Political Culture in the House of Commons, 1800–34

Abstract How easy was it to hear, and be heard, in the historic house of commons? Located in the former St Stephen's Chapel in the Palace of Westminster, the pre‐1834 Commons had not been designed as a place of debate, though its refurbishment by Christopher Wren may have taken acoustics into account. This article focuses on the chamber as re‐ordered by James Wyatt in 1800–1 to accommodate 100 members from Ireland following the Acts of Union. Employing acoustic simulation software and an interdisciplinary methodology, we explore the soundscape of the Commons as experienced both on the floor of the house and in the ventilator space where women gathered to listen to the debates below. Modelling for different scenarios, including speeches delivered from the front and back benches and the Speaker's chair, we present comparative data for their audibility in a fully‐ or half‐occupied house. Evidence for contemporary understanding of the acoustics of the chamber, for instance around the ‘elasticity of the atmospheric air’, is also reviewed in light of modern science. Results are interpreted for their impact on the political culture of the pre‐1834 house of commons including choice of seating, oratorical strategies, and the experience of reporters in the gallery.
