World of Sound

World of Sound is a collection of six lectures delivered by Sir William Henry Bragg at the Royal Institution in December 1919. Aimed at a juvenile audience, these lectures provide an accessible introduction to the science of sound and hearing, along with a historical overview of research in the field. Notably, the final lecture discusses the role of sound in warfare, reflecting on early technologies like acoustic mirrors during a time of significant military innovation. This work is part of the Royal Institution Christmas Lectures, a tradition that began in 1825 to educate young people on scientific topics.
