Hearing loss refers to the impairment in perceiving or processing auditory information. Hearing impairment can be partial or complete, and may occur in one or both ears. The impairment in hearing may be acquired, inherited or caused due to perinatal problems and aging. Tinnitus, hyperacusis and presbycusis, endaural phenomena, and auditory processing disorder are a few hearing disorders. A common cause of hearing loss is chronic ear infection. During pregnancy, infections like rubella and syphilis can lead to hearing loss in the offspring. Hearing loss interferes with spoken language acquisition and causes cognitive decline. Certain cases of hearing loss can be examined medically, while others are irreversible and therefore, permanent. The usage of hearing aids, cochlear implants, sign language and subtitles are principal management tools to aid individuals suffering with this condition. The use of stem cell transplant and gene therapy for the regrowth of cochlear cells and nerve cells will prove highly beneficial in the treatment of hearing loss. This book includes some of the vital pieces of work being conducted across the world, on the various topics related to hearing loss. It will serve as a valuable source of reference on its clinical diagnosis and management for graduate and post graduate students.

Hearing loss is defined as the inability to apprehend sound. There are mainly three forms of hearing loss, namely, sensorineural hearing loss, conductive hearing loss and mixed hearing loss. A number of factors like genetics, ageing, exposure to noise, infections, birth complications, trauma to the ear, and certain medications or toxins can lead to hearing loss. Its primary symptoms involve difficulty in understanding speech, and pain or pressure in the ears. Hyperacusis, tinnitus, vertigo and tympanophonia are some secondary symptoms associated with hearing loss. Diagnostic methods include otoscopy, tympanometry and differential testing. MRI and CT scans are also used to determine the pathology of causes related to hearing loss. The management of this medical issue includes cochlear implants, hearing aids, middle ear implants and assistive technology. The various advancements in the study of hearing loss are glanced at and the management strategies are looked at in detail within this book. Clinicians in search of information to further their knowledge will be greatly assisted by it.

This entertaining and informative guide explains the meanings of bird names, many of which have fascinating origins and stories behind them.The universal system of 'scientific' names, based largely on Greek and Latin, is used in all good bird books and assists birdwatchers around the world in figuring out exactly what they are looking at. While some of the names are fairly self-explanatory - such as Troglodytes for wren, meaning 'cave-dweller' - others are more mysterious - Caprimulgus for nightjar, for example, meaning 'goat-sucker'.Covering hundreds of bird species from around the world, Birds: What's In A Name? includes explanations of hundreds of scientific names and common names, as well as delivering a wealth of other facts and trivia relating to the species concerned. In short, it's the most readable and entertaining book on the subject available anywhere.Anas platyrhynchos (Mallard) 'The duck with the flat beak'.Ixobrychus minutus (Little Bittern) 'Small reed bellower'.Strigops habroptilus (Kakapo) A bird that 'looks like an owl, with soft feathers'.Ptilonorhynchus violaceus (Satin Bowerbird) 'Violet bird with a feathered bill'.Tachybaptus ruficollis (Little Grebe) 'Literally translated, this is the 'red-collared fast-sinker'.

Though poets have always written about cities, the commonest critical categories have stressed the rural, so that poetry can seem irrelevant to a predominantly urban population. This book seeks to redress the balance by exploring work by a range of poets who reflect the contemporary urban scene.

Poetry Wars describes the battle at the National Poetry Society during the 1970s between radicals and conservatives, which had lasting effects on British poetry. Myths and anecdotes about these events have long been circulated, but this is the first detailed account of what happened, based on archival sources, and told by a writer who knew many of those involved.

This book seeks to problematise the very notion of context, which has remained for the most part stubbornly un-theorised and un-examined. The book aims to set a distinction between 'deep' and 'broad' contexts, arguing that we need to counter the prevalence of the latter if literary studies is to avoid becoming a minor branch of history. -- .

This book is about reading and studying poetry. Using fully-worked examples and complete poems wherever possible, it shows all the key elements of poetry 'at work' in poems -- .
