Download or read book Infrasound Its Sources and Its Effects on Man written by and published by . This book was released on 1976 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrasound, sinusoidal pressure variations from 0.1 to 20 Hz, is somewhat more complicated to measure and analyze than sound of higher frequency. But the most common error in analyzing infrasound is not to also measure the higher frequency sounds and then interpret these sounds with respect to their effects on humans. Generally, where there is intense infrasound, there are also intense sounds above 20 Hz; and these are the sounds that cause adverse human effects. At sufficient intensity infrasound is audible, but is easily masked by higher frequency sound. Infrasound does not often occur at levels that are harmful or even audible to man. Thus infrasound exposure is not one of mankinds more pressing environmental problems.

This book was released on 2010-01-19 with total page 739 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of infrasound to monitor the atmosphere has, like infrasound itself, gone largely unheard of through the years. But it has many applications, and it is about time that a book is being devoted to this fascinating subject. Our own involvement with infrasound occurred as graduate students of Prof. William Donn, who had established an infrasound array at the Lamont-Doherty Geological Observatory (now the Lamont-Doherty Earth Observatory) of Columbia University. It was a natural outgrowth of another major activity at Lamont, using seismic waves to explore the Earth’s interior. Both the atmosphere and the solid Earth feature velocity (seismic or acoustic) gradients in the vertical which act to refract the respective waves. The refraction in turn allows one to calculate the respective background structure in these mediums, indirectly exploring locations that are hard to observe otherwise. Monitoring these signals also allows one to discover various phenomena, both natural and man-made (some of which have military applications).

Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first volume “Infrasound monitoring for atmospheric studies” published in 2010, significant advances were achieved in the fields of engineering, propagation modelling, and atmospheric remote sensing methods. The global infrasound network, which consists of the International Monitoring Network (IMS) for nuclear test ban verification completed by an increasing number of regional cluster arrays deployed around the globe, has evidenced an unprecedented potential for detecting, locating and characterizing various natural and man-made sources. In recent years, infrasound has evolved into a broad interdisciplinary field encompassing academic disciplines of geophysics and innovative technical and scientific developments. The advances in innovative ground-based instruments, including infrasound inversions for continuous observations of the stratosphere and mesosphere, provide useful insights into the geophysical source phenomenology and atmospheric processes involved. Systematic investigations into low-frequency infrasound signals and the development of complementary observational platforms point out new insights into the dynamics of the middle atmosphere which play a significant role in both tropospheric weather and climate. This monitoring system also provides continuous relevant information about natural hazards with high societal benefits, like on-going volcanic eruptions, surface earthquakes, meteorites or severe weather. With this new edition, researchers and students benefit from a comprehensive content of both fundamental and applied inter-disciplinary topics.

Available in PDF, EPUB and Kindle. Book excerpt: The infrasound field, the science of low-frequency acoustic waves, has developed into a broad interdisciplinary field encompassing academic disciplines of physics and recent technical and scientific developments. The infrasound network of the International Monitoring Network (IMS) of the CTBT-Organization has demonstrated its capability for detecting and locating infrasonic sources such as meteorites, volcanic eruptions, earthquakes, auroras, mountain associated waves ... Nearly 70% of the global network is now operational and regional cluster arrays are deployed around the globe. Systematic investigations into low-frequency acoustic signals have evidenced an unprecedented potential of the monitoring of infrasonic waves permanently generated by natural and man-made events. Furthermore, recent studies point out new insights on quantitative relationships between observables and atmospheric specifications, and therefore opening new fields into the mathematics of geophysical inverse problems for atmospheric remote sensing. This volume reviews the most important areas of infrasound, with emphasis on the latest researches and applications, e.g. instrumentation, engineering, signal processing, source monitoring, propagation modeling, atmospheric dynamics, global changes, remote sensing methods. Researchers and students will benefit from a comprehensive content of infrasound related topics, where both fundamental and applied topics are discussed by authors from international institutions, all experts in their fields.

Available in PDF, EPUB and Kindle. Book excerpt: "You'll never listen to the world the same way again. A truly ear-opening experience!" —Chris Ferrie, award-winning physicist and author of Where Did the Universe Come From? And Other Cosmic Questions For readers of Neil deGrasse Tyson and Bill O'Neill, What the Ear Hears (and Doesn't) is a fascinating science book for adults that explores the physics principle of frequency and the (sometimes weird) role it plays in our everyday lives. What do the world's loneliest whale, a black hole, and twenty-three people doing Tae Bo all have in common? In 2011, a skyscraper in South Korea began to shake uncontrollably without warning and was immediately evacuated. Was it an earthquake? An attack? No one seemed quite sure. The actual cause emerged later and is utterly fascinating: Twenty-three middle-aged folks were having a Tae Bo fitness class in the office gym on the twelfth floor. Their beats had inadvertently matched the building's natural frequency, and this coincidence—harnessing a basic principle of physics—caused the building to shake at an alarming rate for ten minutes. Frequency is all around us, but little understood. Musician, composer, TV presenter, and educator Richard Mainwaring uses the concept of the Infinite Piano to reveal the extraordinary world of frequency in a multitude of arenas—from medicine to religion to the environment to the paranormal—through the universality of music and a range of memorable human (and animal) stories laced with dry humor. Whether you're science curious, musically inclined, or just want to know what a Szechuan pepper has to do with physics, What the Ear Hears (and Doesn't) is an immensely enjoyable read filled with "did you know?" trivia you'll love to share with friends.

Download or read book Ocean Noise and Marine Mammals written by National Research Council and published by National Academies Press. This book was released on 2003-05-22 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the 119 species of marine mammals, as well as for some other aquatic animals, sound is the primary means of learning about the environment and of communicating, navigating, and foraging. The possibility that human-generated noise could harm marine mammals or significantly interfere with their normal activities is an issue of increasing concern. Noise and its potential impacts have been regulated since the passage of the Marine Mammal Protection Act of 1972. Public awareness of the issue escalated in 1990s when researchers began using high-intensity sound to measure ocean climate changes. More recently, the stranding of beaked whales in proximity to Navy sonar use has again put the issue in the spotlight. Ocean Noise and Marine Mammals reviews sources of noise in the ocean environment, what is known of the responses of marine mammals to acoustic disturbance, and what models exist for describing ocean noise and marine mammal responses. Recommendations are made for future data gathering efforts, studies of marine mammal behavior and physiology, and modeling efforts necessary to determine what the long- and short-term impacts of ocean noise on marine mammals.

Book excerpt: CONVERSATIONAL CHAT INFORMATIVE BOOK Ghost frequencies and infrasound are two topics that have been of interest to paranormal investigators for many years. Ghost frequencies are said to be the sounds that ghosts make, while infrasound is a type of low-frequency sound that is below the range of human hearing. There is no scientific evidence to support the existence of ghost frequencies, but there is some evidence to suggest that infrasound can have a psychological effect on humans. For example, infrasound has been shown to cause anxiety, fear, and even hallucinations. In recent years, there has been some new research on the topic of ghost frequencies and infrasound. For example, a study published in the journal "Frontiers in Psychology" in 2021 found that infrasound can cause people to feel uneasy and anxious. The study also found that infrasound can make people more likely to believe in ghosts. Another study, published in the journal "PLOS One" in 2022, found that infrasound can cause people to experience hallucinations. The study found that infrasound can cause people to see and hear things that are not there. While these studies do not prove the existence of ghosts, they do suggest that infrasound can have a significant impact on human psychology. This suggests that infrasound may play a role in some of the paranormal experiences that people report. It is important to note that more research is needed to fully understand the impact of infrasound on humans. It is also important to note that infrasound is not the only explanation for paranormal experiences. There are many other possible explanations, such as psychological factors, environmental factors, and even fraud. Overall, the latest developments in the research on ghost frequencies and infrasound are intriguing. However, more research is needed to fully understand the impact of infrasound on humans and to determine whether it plays a role in paranormal experiences.

Download or read book The Inaudible Symphony written by Läslo Gerardus Evers and published by . This book was released on 2008 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the complete sequence of measuring, processing and interpreting infrasound data. A microbarometer was developed and deployed in arrays to measure infrasound. Array processing and statistical detection techniques are applied to extract signals of interest from the continuous recording. Knowledge on the atmospheric propagation appeared essential in identifying infrasonic sources like meteors, volcanoes, sea waves and accidental chemical explosions. A large amount of coherent infrasound is continuously being detected from both natural and man-made sources, i.e. the inaudible symphony. Applications are foreseen in acoustic remote sensing where infrasound can be used as passive probe for the upper atmosphere. Non-acoustic phenomena, like gravity waves, can also be detected with the methods described in this thesis.
