‘Whispers In Air’ explores the intricate science of sound, using whispers as a focal point to reveal complex interactions between physics, biology, and technology. The book delves into the fundamental properties of sound waves, examining how they are generated, propagated, and influenced by different environments. Intriguingly, the book highlights how both humans and animals use whispers for strategic communication, revealing the evolutionary advantages of this subtle form of interaction.
The book progresses through three sections, starting with the physics of sound, then moving into the use of whispers in communication, and finally examining the science of eavesdropping and acoustics. It connects theoretical physics with practical applications, demonstrating how an understanding of acoustics impacts fields from medicine to national security. The book also touches upon the ethical considerations surrounding acoustic surveillance, and the potential for misuse of audio technology.
Adopting a conversational yet informative tone, ‘Whispers In Air’ aims to demystify the complex world of acoustics for a broad audience. It draws from classic experiments and recent studies in animal communication, as well as cutting-edge research in signal processing, to provide a comprehensive overview of the science of sound.
