Genes causing hearing loss display various modes of inheritance, with autosomal recessive being the most common. With so many cases of hearing loss having a genetic etiology, audiologists are certain to encounter these patients on a fairly regular basis. Audiologists who possess basic knowledge about genetics are better equipped to recognize when a genetics referral is warranted, thereby enhancing patient care. In this chapter, it is determined that a genetics evaluation can yield valuable information for patients and their families, such as prognosis, estimates of recurrence risks, and diagnosis of other family members. The second chapter will review causes of revision surgery, how to diagnose cases of failed cochlear implants and will discuss surgical and audiological outcome of revision cochlear implant surgeries, Speech recognition ability with a replacement cochlear implant may significantly increase or decrease from that with the original implant. Experienced cochlear implant patients facing reimplantation must be counseled regarding the possibility of differences in sound quality and speech recognition performance with their replacement device. The purpose of the following chapter is to correlate the results obtained through questionnaires concerning self-reported restriction in social participation and patient satisfaction / benefit with objective time assessment of device use. This is a descriptive, cross-sectional study sample composed of and elderly and non-elderly adults of both sexes diagnosed with hearing loss and approved as candidates for hearing aid fitting at a university hospital. The goal of chapter four is to understand the main features of human posture and how it is possible to analyze it. The aim of this chapter is to investigate the influence of hearing loss and vestibular disorders on body posture. The objective of the concluding chapter was to analyze the auditory brainstem response (ABR) and frequency following response (FFR) in patients diagnosed with Sickle Cell Disease (SCD) who were referred to the outpatient hemoglobinopathy clinic at a public hospital in southern Brazil.

With chapters from audiology professionals from around the world, Advances in Audiology and Hearing Science presented in two volumes--provides an abundance of information on the latest technological and procedural advances in this ever-improving field. Volume 1 primarily focuses on revised clinical protocols and provides information on new research to help guide decisions and criteria regarding diagnosis, management, and treatment of hearing-related issues. Topics include new clinical applications such as auditory steady-state response, wideband acoustic immittance, otoacoustic emissions, frequency following response, noise exposure, genomics and hearing loss, and more. Volume 2: Otoprotection, Regeneration, and Telemedicine includes sections with material related to hearing devices, hearing in special populations, such as the children and the elderly, as well chapters on the fast-growing subfields of otoprotection and regeneration, including pharmacologic otoprotection, stem cells, and nanotechnology.

Exposure to loud noise continues to be the largest cause of hearing loss in the adult population. The problem of NIHL impacts a number of disciplines. US standards for permissible noise exposure were originally published in 1968 and remain largely unchanged today. Indeed, permissible noise exposure for US personnel is significantly greater than that allowed in numerous other countries, including for example, Canada, China, Brazil, Mexico, and the European Union. However, there have been a number of discoveries and advances that have increased our understanding of the mechanisms of NIHL. These advances have the potential to impact how NIHL can be prevented and how our noise standards can be made more appropriate.

The loss of hearing - be it gradual or acute, mild or severe, present since birth or acquired in older age - can have significant effects on one's communication abilities, quality of life, social participation, and health. Despite this, many people with hearing loss do not seek or receive hearing health care. The reasons are numerous, complex, and often interconnected. For some, hearing health care is not affordable. For others, the appropriate services are difficult to access, or individuals do not know how or where to access them. Others may not want to deal with the stigma that they and society may associate with needing hearing health care and obtaining that care. Still others do not recognize they need hearing health care, as hearing loss is an invisible health condition that often worsens gradually over time. In the United States, an estimated 30 million individuals (12.7 percent of Americans ages 12 years or older) have hearing loss. Globally, hearing loss has been identified as the fifth leading cause of years lived with disability. Successful hearing health care enables individuals with hearing loss to have the freedom to communicate in their environments in ways that are culturally appropriate and that preserve their dignity and function. Hearing Health Care for Adults focuses on improving the accessibility and affordability of hearing health care for adults of all ages. This study examines the hearing health care system, with a focus on non-surgical technologies and services, and offers recommendations for improving access to, the affordability of, and the quality of hearing health care for adults of all ages.

The volume also includes a section on canine audiology, allowing students and professionals a broader exposure to hearing science.

Evaluating and Conducting Research in Audiology is the first research methods textbook that is specific to the field of audiology and designed to serve as an academic textbook for audiology graduate students. This text can also be accessible for audiology practitioners who are interested in clinical and applied research. The comprehensive coverage includes materials for multiple courses within audiology degree programs, including research methods, analysis of professional literature, evidence-based practice, and capstone research projects. Classroom tested, and written by authors who have extensive backgrounds in publishing and editing, this text provides knowledge that is required in evaluating, conducting, and disseminating research. The book is separated into three sections: (a) research methods; (b) evidence-based practice; and (c) conducting and disseminating research. Together, these sections provide a detailed coverage of the research methods that are relevant to conducting research, particularly in the field of Audiology. Key Features: * Learning outcomes at the beginning of each chapter * End of chapter reviews including key points and study questions * Audiology-specific examples, research methods, and study designs * “Golden Nugget” boxes throughout the book containing valuable information related to the critical concepts * In-depth discussion of qualitative research methods, survey research methods, and systematic reviews to motivate students and early career researchers to consider these methodologies in their research

Cochlear Implants: Advances, Efficacy and Future Directions assesses the growing need to provide other measures for assessing the impact of cochlear implantation. As such, this book aims to evaluate the Cross-Modal Plasticity in deaf children with visual-impairment after CI use, through the analysis of changes in the topographic distribution of the cortical response of Somatosensory Evoked Potential by stimulation of the median nerve. The authors describe the results of Low-Resolution Brain Electromagnetic Tomography (LORETA) used for the localization of electrical neuronal source generators of SEP N20 response in deaf children with visual-impairment. The following chapter discusses and evaluates the effectiveness of the application of bilateral CIs in children, either sequentially or binaurally, affected by severe sensorineural hearing loss. Although the benefits of bilateral implants in adults have been established, the available data regarding children is still limited. In the last chapter, a surgeon and developer of the surgical virtual reality system of the temporal bone shares his expertise on the future of this virtual reality to maximize the goal of cochlear implant surgery. Many studies have found that virtual reality simulators have improved the operative performance of the trainees. (Nova Biomedical) --
