Paperback. Etat : New. Print on Demand. This book reveals the surprising findings of a 19th century United States Lighthouse Board investigation into unreliable fog signals. It begins by describing the Board's initial assumption that sound carries evenly in all directions from its source. However, through a series of experiments and real-world observations, the author demonstrates how this assumption is far from accurate. Factors such as wind direction, temperature, and even the shape of the coastline can dramatically affect the audibility of fog signals, and create areas where the sound is completely inaudible or greatly reduced in volume. The book presents a wealth of evidence, including tables and firsthand accounts, to support these findings, and it concludes with practical advice for navigators on how to use fog signals safely and effectively. This book challenges long-held beliefs about sound propagation and provides valuable insights for anyone interested in marine safety, acoustics, or the history of technology. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781333857530_0
