World of Sound

Curious about vibration, hearing, and the technologies born of conflict? World of Sound by Sir William Henry Bragg delivers six lucid Royal Institution Christmas Lectures that introduce the fundamentals of acoustics with clarity and charm. Bragg, writing for a young and general audience in 1919, explains how sound is produced, travels, and is perceived by the ear, blending clear demonstrations with a brisk history of research into waves, resonance, and hearing. The lectures balance hands-on explanation with thoughtful context: early 20th-century experiments, the practical applications of acoustics, and contemporary wartime uses such as acoustic mirrors and early submarine detection ideas. Bragg’s measured scientific voice reveals how a foundational branch of physics informed both everyday life and emerging technologies in the shadow of the First World War. Perfect for listeners who enjoy classic popular science, history of science enthusiasts, students, and educators, this science audiobook is an inviting primer on sound—timeless in its explanations and vivid as a historical snapshot of scientific thinking after the Great War.
