The Basics Of Sound

Everyday your world is filled with a multitude of sounds. Sound can let you communicate with others or let others communicate with you. It can be a warning of danger or simply an enjoyable experience. Some sounds can be heard by dogs or other animals but cannot be heard by humans. The ability the hear is definitely an important sense, but people who are deaf are remarkable in the ways that they can compensate for their loss of hearing All of the sounds you can hear from plucking the strings above occur because mechanical energy produced by your computer speaker was transferred to your ear through the movement of atomic particles. Sound is a pressure disturbance that moves through a medium in the form of mechanical waves. When a force is exerted on an atom, it moves from its rest or equilibrium position and exerts a force on the adjacent particles. These adjacent particles are moved from their rest position and this continues throughout the medium. This transfer of energy from one particle to the next is how sound travels through a medium. The words "mechanical wave" are used to describe the distribution of energy through a medium by the transfer of energy from one particle to the next. Waves of sound energy move outward in all directions from the source. Your vocal chords and the strings on a guitar are both sources which vibrate to produce sound waves. Without energy, there would be no sound. Let's take a closer look at sound waves

Sound Propagation Sound propagates through air as a longitudinal wave. The speed of sound is determined by the properties of the air, and not by the frequency or amplitude of the sound. Sound waves, as well as most other types of waves, can be described in terms of the following basic wave phenomena.

Ticking clocks, claps of thunder, the human voice—sound is anything that can be heard. Hearing sound is one thing, but understanding just how it works and what its properties are is quite another. Answering these questions and others concerning supersonic speed and breaking the sound barrier, how the human voice and ear work, and the age-old question of whether a tree falling in the forest unobserved makes any noise, this volume provides an accessible yet detailed and amply illustrated guide to the science of sound. Also included are several fun projects, which allow readers to explore in a hands-on way the nature, quality, and behavior of sound.

Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

This Title Introduces Students To The Basic Concept Of Sounds. How Sounds Can Be Heard But Not Seen. How Sound Is A Form Of Energy That Is Transmitted Through Sound Waves Which Travel Through Your Eardrum To Be Heard. How Sound Travels Through Air And At What Rate Of Speed. Useful Examples Are Given Throughout To Help Students Understand The Concept.

Sound is integral to how we experience the world, in the form of noise as well as music. But what is sound? What is the physical basis of pitch and harmony? And how are sound waves exploited in musical instruments? In this Very Short Introduction Mike Goldsmith looks at the science of sound and explores sound in different contexts, covering the audible and inaudible, sound underground and underwater, accoustic and electric, and hearing in humans and animals. He also considers the problem of sound out of place - noise and its reduction. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Basics of Audiology was developed from Dr. Cranford'’s extensive experience teaching audiology to speech-language pathology (SLP) students. Although there are multiple, established introductory texts in audiology, this text is uniquely geared to students who specifically studying speech-language pathology. The book includes all the necessary audiological principles needed for any SLP student to become competent in test assessment and the diagnosis of hearing disorders. Mastery of this text will enable the future clinician practice in a wider patient base. In addition to being useful in undergraduate training programs as a primary or supplementary text, the book will also be valuable for SLPs who have “been in the trenches” for a number of years and feel they need to have their knowledge of audiology refreshed or updated. Because the author has focused on using nontechnical or layman’s terminology in explaining the various scientific and clinical concepts/principles in this field, he also believes that parents, relatives, or significant others of hearing impaired patients will also find this book useful for understanding the problems experienced by their loved ones.
