Background Noise

The rise of a prominent auditory culture, reveals the degree to which sound art is lending definition to the 21st Century. And yet sound art still lacks related literature to compliment, and expand, the realm of practice. Background Noise sets out an historical overview, while at the same time shaping that history according to what sound art reveals - the dynamics of art to operate spatially, through media of reproduction and broadcast, and in relation to the intensities of communication and its contextual framework

A comprehensive overview of seismic ambient noise, covering observations, physical origins, modelling, processing methods and applications in imaging and monitoring.

Background Noise follows the development of sound as an artistic medium and illustrates how sound is put to use within modes of composition, installation, and performance. While chronological in its structure, Brandon LaBelle's book is informed by spatial thinking - weaving architecture, environments, and the specifics of location into the work of sound, with the aim of formulating an expansive history and understanding of sound art. At its center the book presupposes an intrinsic relation between sound and its location, galvanizing acoustics, sound phenomena, and the environmental with the tensions inherent in what LaBelle identifies as sound's relational dynamic. For the author, this is embedded within sound's tendency to become public expressed in its ability to travel distances, foster cultural expression, and define spaces while being radically flexible. This second expanded edition includes a new chapter on the non-human and subnatural tendencies in sound art, revisions to the text as well as a new preface by the author. Intersecting material analysis with theoretical frameworks spanning art and architectural theory, performance studies and media theory, Background Noise makes the case that sound and sound art are central to understandings of contemporary culture.

This synthesis report describes current practice in mitigating nighttime construction nuisances such as noise, vibration, light, and dust. Roadway construction work is increasingly done at night to mediate traffic congestion; however, this trend also increases the potential for disturbing adjacent property owners. This report will be of interest to department of transportation (DOT) construction, design, and project engineers, and to those responsible for community relations. This report of the Transportation Research Board stresses the importance of informing project neighbors and establishing cooperative relations with the community as a first measure of successful mitigation. Examples show how project design can address construction nuisances by locating and sequencing construction operations to minimize their impact. Current practices used in source control, path control, and receptor control are described and documented in examples from the Boston Central Artery/Tunnel project and projects in Arizona and Salt Lake City, Utah. Appended materials provide sample specifications for mitigation of noise and dust control.

Chilling stories of unexplained events, perfect for true crime fans! In every corner of this earth there are secrets. They are hidden in the dark edge of the woods, nestled in the cold stars, and staring out from a stranger's eyes. And whether they be demonic possession or an unsolved murder, the unknown has always haunted our dreams. From the hit podcast Unexplained comes a volume perfectly crafted for the curious, the cynical, and the not-easily-frightened. Richard Maclean Smith is the expert in the unknown, and humbly offers up ten tales of real-life events that continue to evade explanation. With these chilling stories comes the missing key: a connection to our own beliefs in science, superstition, and perception. From cryptic accounts of spectral sightings to peculiar tales of time anomalies, Smith delves into each case with meticulous research, thoughtful insights, and a respectful approach. Unexplained encourages readers to question the boundaries of our understanding, proving that reality can be more extraordinary than we ever imagined. Embark on this gripping journey into the unknown with Unexplained: Supernatural Stories for Uncertain Times. Key Features: Thought-Provoking: Challenges readers to question their understanding of reality and embrace the inexplicable. Well-Researched: Offers meticulously researched accounts of paranormal phenomena and unexplained events. Engaging Storytelling: Features a narrative style that is both engaging and respectful, based on the popular Unexplained podcast. Wide Range of Topics: Explores a diverse range of phenomena from spectral sightings to time anomalies. Cultural Perspective: Includes historical, cultural, and scientific context for each story, adding depth to the mystery.

Compiling strategies from more than 30 years of experience, this book provides numerous case studies that illustrate the implementation of noise control applications, as well as solutions to common dilemmas encountered in noise reduction processes. It offers methods for predicting the noise generation level of common systems such as fans, motors, c

This monograph develops the theory of noise mechanisms and measurements, and describes general noise characteristics and computational methods. The vast ambient noise literature is concisely summarized using theory combined with key representative results. The air sea boundary interaction zone is described in terms of nondimensional variables requisite for future experiments. Noise field coherency, rare directional measurements, and unique basin scale computations and methods are presented. The use of satellite measurements in these basin scale models is demonstrated. A series of appendices provides in-depth mathematical treatments which will be of interest to graduate students and active researchers.
