This book brings together many of the main conclusions of the European Concerted Action Programme on Genetic Hearing Impairment (HEAR). It is spilt into four sections, covering definitions, protocols, genotype/phenotype relationships and important websites.The section on definitions enables all those approaching the problems of Genetic Hearing Impairment from different backgrounds to communicate in the same language and understand what each is doing more clearly. The definitions are of Audiological, Vestibulogical, Epidemiological and Genetic terms, together with specific terms associated with particular craniofacial abnormalities. The second section comprises protocols for the minimal set investigation of patients and their family members with genetic hearing impairment. Relatively little work has been done in the past on the balance of disorders which may be associated with Genetic Hearing Impairment and a protocol aiming to elucidate some of these factors in a relevant way has been defined. The final chapter in this section deals with how audiologists should relate to genetic laboratories in an attempt to reduce the confusion which has risen in this field in the past. The third section is concerned with the relationship between genotypes and phenotypes in non-syndromal hearing impairment in the conditions in which the genes have so far been localised and in many cases identified. The final section deals with the important websites within this field. The most important and the most visited is the Hereditary Hearing Loss website based on Antwerp and managed by Guy Van Camp and Richard Smith.

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.

Living with Hearing Difficulties is a source-book for professionals who encounter and support individuals with hearing difficulties. It will also be of interest to people with hearing difficulties themselves and those close to them. The book highlights the concept of audiological enablement as being an interactive process requiring the active involvement of both clinician and patient. The thirteen chapters encompass four sections which broadly follow the categories of the World Health Organization's ICF (2001): Section 1 addresses types of hearing disorders, the impairments they cause and also the process of help seeking. Section 2 deals with the effects of hearing impairment on communication and psychosocial functioning. Section 3 considers the individual in their environment; their family, work, and leisure. Section 4 elaborates on the process of enablement in a non-prescriptive manner. The authors approach the problems and needs from the standpoint of what the patient/client is seeking. Enablement is seen as a team effort between the professionals, the patient and their family in an ever-changing environment. This entails using any relevant techniques to ensure the well-being of the individual with hearing impairment; that end remains very much their goal. The book also has a companion website www.wiley.com/go/stephens which hosts additional downloadable documents as well as a demonstration of the concept of the signal-to-noise ratio.

Many children with developmental language disorder (DLD) exhibit difficulties with phonology, i.e. the sounds of language. Children with any degree of hearing impairment (HI) are at an increased risk of problems with spoken language, including phonology. The cause of these difficulties is unknown in children with DLD, and is often assumed to result from reduced hearing acuity in children with HI. Variability in terms of language outcomes is large in both groups, and determining if a child’s language ability is within normal limits or not is problematic. A task that has proven useful in differentiating typical from atypical language development is nonword repetition, in which the child listens to a word form without meaning and repeats it back immediately. Performance in nonword repetition tasks is a potential indicator of language ability in both children with DLD and children with HI. However, it has not been established exactly what the task measures. In the present thesis, the ability to repeat prosodic and segmental features of real words and nonwords was investigated in Swedish-speaking four- to six-year-old children with DLD and HI, as well as in children with normal hearing and typical language development (TLD) (papers I, II and III). Further, relations of word and nonword repetition ability to language and hearing were explored (papers II and III), along with comparisons of phonological and grammatical production between the groups (paper IV). The findings indicated that the prosodic features stress and tonal word accent affect repetition performance in children with DLD, HI, and TLD. In general, the children with DLD and HI achieved lower results than the children with TLD on repetition of segments (consonants and vowels) and prosodic features, but tonal word accent was repeated with relatively high accuracy. Tonal word accent 1 was more accurately repeated than tonal word accent 2 by the DLD and HI children. The children with TLD repeated tonal word accent with few errors, but segments in nonwords with tonal word accent 2 were easier to repeat than segments in nonwords with tonal word accent 1. The results further revealed that the ability of children with DLD to repeat stress in real words is related to expressive grammar, but repetition of prosodic features does not reflect general language knowledge. In contrast, repetition of both segmental and prosodic nonword features may be indicative of receptive vocabulary, phonological production during naming of familiar words, and expressive grammar in children with HI. Repetition performance might be related to the degree of HI before cochlear implantation or fitting of hearing aids. Children with DLD and children with HI demonstrate similar strengths and weaknesses in phonological and grammatical production, despite the fact that they develop language under different conditions—with and without normal hearing. Tonal word accent use and syntax are relatively unimpaired in DLD and HI children. This thesis highlights prosodic and phonological strengths and weaknesses in children who have, or are at risk of, deficits in language and communication abilities. It also supports word and nonword repetition as potential predictors of some aspects of language ability in children with DLD and HI. Further, it emphasizes the importance of taking prosody into account when constructing, or interpreting results from, repetition tasks. Future research aiming to investigate the relationship between prosody in repetition and language, cognition and hearing, should use longitudinal study designs, and include younger children. Studies comparing prosodic and phonological ability in children with DLD and children with HI should employ both quantitative and qualitative analyses.

The Indian subcontinent is a vast land mass inhabited by over one billion people. Its rich and varied history is reflected by its numerous racial and ethnic groups and its distinct religious, cultural and social characteristics. Like many developing countries in Asia, it is passing through both demographic and epidemiological transitions whereby, at least in some parts, the diseases of severe poverty are being replaced by those of Westemisation; obesity, diabetes, and heart disease, for example. Indeed, as we move into the new millennium India has become a land of opposites; on the one hand there is still extensive poverty yet, on the other hand, some of the most remarkable developments in commerce and technology in Asia are taking place, notably in the fields of information technology and biotechnology. India has always fascinated human geneticists and a considerable amount of work has been done towards tracing the origins of its different ethnic groups. In the current excitement generated by the human genome project and the molecular and genetic approach to the study of human disease, there is little doubt that this field will develop and flourish in India in the future. Although so far there are limited data about genetic diseases in India, enough is known already to suggest that this will be an extremely fruitful area of research.

This book systematically discusses the pathogenesis, prevention, and the current and potential clinical treatment of hearing loss, as well as the latest advances in hearing research. Hearing loss is a prevalent sensory disorder, which according to a 2015 World Health Organization (WHO) report affected 9% of the global population in 2015. As populations continue to age, more and more people are suffering from the condition, with 60% of those aged between 65 and 75 affected. Hearing loss seriously affects patients’ ability to work ability and quality of life, and as such deafness has become an increasingly urgent social problem around the globe. Sensorineural hearing loss is mainly caused by damage to the hair cells (HCs), and the subsequent loss of spiral ganglion neurons (SGNs). Damage to the HCs in the inner ear can result from exposure to loud noises and environmental and chemical toxins as well as genetic disorders, aging, and certain medications. This book provides ENT specialists and researchers, as well as individuals affected a comprehensive introduction to the field of hearing loss.
