Paperback. Condición: New. Print on Demand. This book provides the reader with an insightful account regarding the acoustic properties of a range of building materials. It provides a detailed account of the relevant scientific principles and methodologies used to measure sound transmission and absorption. The author presents a historical overview of acoustic research, with a focus on the development of methods for quantifying sound absorption and transmission in building materials. The book includes detailed descriptions of the construction and testing of a variety of panels, providing valuable data on their acoustic properties. The author also delves into the theoretical underpinnings of absorption measurements, explaining the concepts of reverberation time and surface absorptivity. Moreover, this book offers practical guidance on the selection and use of sound-absorbing materials in architectural design, making it an essential resource for architects, engineers, and anyone interested in creating acoustically comfortable spaces. 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.…

Paperback. Condición: New. Print on Demand. This book is a collection of research on the transmission of sound conducted by the Bureau of Standards. The author set out to study how sound is transmitted and absorbed in tubes, especially those used aboard ships for communication. The research was initiated to help improve the ability for sailors aboard ships to communicate. The author studied different materials, shapes, and lengths of tubes to test their effectiveness at transmitting voice sounds. The experiments yielded specific findings on intensity and articulation. The results have broad applications for sound absorption and transmission in many industries.
