The Telephone An Account of the Phenomena of Electricity, Magnetism, and Sound, as Involved in Its Action

The Telephone: An Account of the Phenomena of Electricity, Magnetism, and Sound, as Involved in Its Action by Amos E. Dolbear is a vivid 19th‑century account that explains how early telephony grew from experiments in electricity, magnetism, and acoustics. Part science manual, part history of technology, Dolbear’s clear prose guides listeners through the physical principles behind sound transmission and the speaking telephone, rooted in the lively public demonstrations and inventive culture of the 1870s. Dolbear unpacks electromagnetic induction, the behavior of sound waves, and tone composition with practical illustrations and a useful table showing the constituents of musical sounds. He recounts his work on magneto‑electric currents and describes his original speaking telephone, offering explicit, tested directions for constructing a working apparatus. The audiobook balances technical explanation with historical context, making complex phenomena accessible to nontechnical listeners while preserving the experimental detail useful to hobbyists. Ideal for listeners interested in the history of science, early telecommunications, DIY experimenters, and students of physics, this nonfiction classic provides foundational insight into how electricity and sound were harnessed to create the telephone and why those discoveries mattered.
