The world is awash with sound waves, they are all around us. However sound is so much more than simply a soundtrack to our lives, and the more we’ve discovered about the physics of sound, the more extraordinary the secrets it has revealed.
In this surprising and engrossing two part series Dr Helen Czerski will go on a spectacular journey into the world of sound to discover what it is, how it’s detected and what it can tell us about the world, and even the universe. From the top of one of Europe’s most active volcanoes to Big Ben, Helen will explore the limits of sound.
Helen also examines how the very nature of sound has helped us survive, communicate and explore our surroundings. From imaging the vocal cords of singer Lesley Garrett to tracing the development of sonar technology Helen probes the power of sound to communicate, revealing how sound has helped us see underwater, driven the evolution of extraordinary biological systems and helped us understand our planet.
Packed with spectacular imagery, jaw-dropping experiments and some of the most remarkable sounds you’ve ever heard, this is the ultimate guide to one of our universe’s most magical phenomena.
