Basic of sound and hearing Part 4 building acoustics by prof.Ibrahim elnoshokaty Pdf

Building acoustics is the science of controlling noise in buildings. This includes the minimization of noise transmission from one space to another and the control of the characteristics of sound within spaces themselves. Building acoustics are an important consideration in the design, operation and construction of most buildings, and can have a significant impact on health and wellbeing, communication and productivity. They can be particularly significant in spaces such as concert halls, recording studios, lecture theatres, and so on, where the quality of sound and its intelligibility are very important. Building acoustics can be influenced by: The geometry and volume of a space. The sound absorption, transmission and reflection characteristics of surfaces enclosing the space and within the space. The sound absorption, transmission and reflection characteristics of materials separating spaces. The generation of sound inside or outside the space. Airborne sound transmission. Impact noise.

basics of sound and hearing by professor Ibrahim elnoshokaty Pdf

In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.[1] Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimeters (0.67 in). Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician, while someone working in the field of acoustical engineering may be called an acoustical engineer.[2] An audio engineer, on the other hand, is concerned with the recording, manipulation, mixing, and reproduction of sound. Applications of acoustics are found in almost all aspects of modern society, subdisciplines include aeroacoustics, audio signal processing, architectural acoustics, bioacoustics, electro-acoustics, environmental noise, musical acoustics, noise control, psychoacoustics, speech, ultrasound, underwater acoustics, and vibration.

Material Selection for Thermoplastic Parts by Michel Biron Pdf

As new applications are developed and plastics replace traditional materials in a widening spectrum of existing applications, the potential personal injury, property damage, financial and legal consequences of failure can be high. However, nearly half of plastics failure can be traced back to the original specification and selection of the material. This book gives engineers the data they need to make an informed decision about the materials they use in their products, imparting a thorough knowledge of the advantages and disadvantages of the various materials to choose from. The data also suggests other candidate materials which the reader may not have originally considered. More than 30,000 thermoplastics grades are grouped into circa. 300 subfamilies, within which over 20 properties are assessed. The abundance or scarcity of a material and its cost are also often important deciding factors. In this book, an economical overview of the plastics industry helps clarify the actual consumption and costs of thermoplastics including bioplastic, and the relationship of cost vs. performance is also examined for each thermoplastic subfamily. Immediate and long-term common properties are reviewed, including mechanical behavior, impact, thermal properties, and many more. Environmental considerations are also covered, including ease of recycling and sustainability. Helps engineers to implement a systematic approach to material selection in their work Includes more than 300 subfamilies of thermoplastic, and a wide range of properties including chemical resistance, thermal degradation, creep and UV resistance Evaluates cost/performance relations and environmental considerations

The Neurosciences and the Practice of Aviation Medicine by Anthony N. Nicholson Pdf

This book brings the neurosciences to operational and clinical aviation medicine. It is concerned with the physiology and pathology of circadian rhythmicity, orientation, hypotension and hypoxia, and with disorders of the central nervous system relevant to the practice of aviation medicine. The chapters on circadian rhythmicity and orientation deal with the impaired alertness and sleep disturbance associated with desynchrony and with the effects of linear and angular accelerations on spatial awareness. Hypotension and hypoxia cover cerebral function during increased gravitational stress, clinical aspects of exposure to acute hypoxia, the mild hypoxia of the cabin of transport aircraft, adaptation and acclimatization to altitude and decompression at extreme altitudes and in space. Disorders of particular significance to the practice of aviation medicine such as excessive daytime sleepiness, epilepsy, syncope, hypoglycaemia, headache and traumatic brain injury are covered, while neuro-ophthalmology, the vestibular system and hearing also receive detailed attention. The potentially adverse effects of the aviation environment and of disorders of the nervous system are brought together, and the text covers the neurological examination as it relates to aircrew and explores current management and therapeutics. The Neurosciences and the Practice of Aviation Medicine is an essential work for those involved in the practice of aviation medicine where familiarity with the effects of the aviation environment on the nervous system and understanding the pathophysiology of relevant clinical disorders are of prime concern. The authors from leading centres of excellence are physiologists concerned with the aviation environment and physicians involved in the day-to-day practice of medicine. They bring to this authoritative text wide experience and expertise in both the experimental and clinical neurosciences.

Sound by Bella Bathurst Pdf

“A moving and fascinating book about sound and what it means to be human” from the Somerset Maugham Award–winning author of The Lighthouse Stevensons (Financial Times). In this surprising and moving book, award-winning writer Bella Bathurst shares the extraordinary true story of how she lost her hearing and eventually regained it and what she learned from her twelve years of deafness. Diving into a wide-ranging exploration of silence and noise, she interviews psychologists, ear surgeons, and professors to uncover fascinating insights about the science of sound. But she also speaks with ordinary people who are deaf or have lost their hearing, including musicians, war veterans, and factory workers, to offer a perceptive, thought-provoking look at what sound means to us. If sight gives us the world, then hearing—or our ability to listen—gives us our connections with other people. But, as this smart, funny, and profoundly honest examination reveals, our relationship with sound is both more personal and far more complex than we might expect. “Bathurst is a restless, curious writer . . . After reading this book, I found myself listening in a richer and more interested way.” —The Guardian “A hymn to the faculty of hearing by someone who had it, lost it and then found it again, written with passion and intelligence . . . terrifying, absorbing and ultimately uplifting.” —Literary Review “Bathurst’s affecting memoir will enlighten and educate.” —Publishers Weekly “A memoir of hearing loss and what the author learned . . . through her unexpected recovery from it. A good writer knows material when it presents itself, and Bathurst is a very good writer.” —Kirkus Reviews
