From These Bare Bones
A fundamental component of the study of worked osseous objects is the identification of the raw materials chosen to make them. In archaeological contexts many objects become degraded to the point where identification is very difficult and the way in which these materials decay during burial and upon excavation can vary greatly. Correct identification is crucial to the investigation of objects, their conservation and future curation. Above all, understanding raw material selection aids our understanding of human-animal interaction in the past both on pragmatic and symbolic levels since the choices made by artisans vary by cultural tradition as well as availability. The 20 papers presented her...
Illusion in Cultural Practice
This volume explores illusionism as a much larger phenomenon than optical illusion, magic shows, or special effects, as a vital part of how we perceive, process, and shape the world in which we live. Considering different cultural practices characterized by illusionism, this book suggests a new approach to illusion via media theory. Each of the chapters analyses a specific kind of illusionistic practice and the concept of illusionism it entails in a given context, including philosophy, perception and cognitive theory, performance magic, occultism, optics, physiology, early cinema, cartomancy, spiritualism, architecture, shamanic rituals, and theoretical physics, to show the diversity of shap...
Basic of sound and hearing Part 4 building acoustics
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
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. A...
