Book Synopsis Hearing Loss by : National Research Council
Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Critical Band Based Spectral Compression by : Vikrant Patil
Download or read book Critical Band Based Spectral Compression written by Vikrant Patil and published by LAP Lambert Academic Publishing. This book was released on 2012-05 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Individuals with sensorineural hearing impairment often experience difficulty in understanding speech. This can be attributed to the widened auditory filters, which results in greater spectral spread across the critical bands and thus causing increased spectral masking. Off late various methods have been used to compress the signal towards the center of the critical band. In our study we have used gammatone filters to split the speech signal into various bands and each critical band was compressed along the frequency axis. 30 hearing impaired subjects participated in a perceptual judgment and speech identification task. From the results of our study we confirmed that processed speech became more intelligible. Thus our study highlights the need for devising a processing algorithm that can achieve spectral compression of signal towards the center of critical band in real-time. Such a processing algorithm when incorporated in digital hearing aids may prove to be beneficial for individuals with sensorineural hearing loss to improve their perceived speech intelligibility.

Book Synopsis Smartphone Based Multi-channel Dynamic-range Compression for Hearing Aid Research and Noise-robust Speech Source Localization Using Microphone Arrays by : Yiya Hao
Download or read book Smartphone Based Multi-channel Dynamic-range Compression for Hearing Aid Research and Noise-robust Speech Source Localization Using Microphone Arrays written by Yiya Hao and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic-range compression (DRC) is one technique of audio signal processing which maps the wide dynamic range of audio into the narrow range. In most of hearing aid devices (HADs), DRC plays as an important role to help hearing impaired people to listen to the speech with better quality and intelligibility. Compared to single-channel DRC, multi-channel DRC additionally improves the audio quality and intelligibility by setting appropriate adjustment parameters for every frequency band. Since most HADs are costly and unaffordable, fitting multi-channel DRC into smartphones becomes an outstanding solution since most people own smartphones. In this dissertation, three types of multi-channel DRCs has been proposed including their real-time implementations on smartphones. Speech Source Localization (SSL) (or Direction of Arrival (DOA) estimation) is another topic in this dissertation, which identifies the direction of the talker of interest in a noisy environment using multiple fixed microphones (known as a Microphone Array). This Proposal mainly covers only DRC, DOA and real-time implementation.
Book Synopsis Bandwidth Extension of Speech Using Perceptual Criteria by : Visar Berisha
Download or read book Bandwidth Extension of Speech Using Perceptual Criteria written by Visar Berisha and published by Springer Nature. This book was released on 2022-06-01 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bandwidth extension of speech is used in the International Telecommunication Union G.729.1 standard in which the narrowband bitstream is combined with quantized high-band parameters. Although this system produces high-quality wideband speech, the additional bits used to represent the high band can be further reduced. In addition to the algorithm used in the G.729.1 standard, bandwidth extension methods based on spectrum prediction have also been proposed. Although these algorithms do not require additional bits, they perform poorly when the correlation between the low and the high band is weak. In this book, two wideband speech coding algorithms that rely on bandwidth extension are developed. The algorithms operate as wrappers around existing narrowband compression schemes. More specifically, in these algorithms, the low band is encoded using an existing toll-quality narrowband system, whereas the high band is generated using the proposed extension techniques. The first method relies only on transmitted high-band information to generate the wideband speech. The second algorithm uses a constrained minimum mean square error estimator that combines transmitted high-band envelope information with a predictive scheme driven by narrowband features. Both algorithms make use of novel perceptual models based on loudness that determine optimum quantization strategies for wideband recovery and synthesis. Objective and subjective evaluations reveal that the proposed system performs at a lower average bit rate while improving speech quality when compared to other similar algorithms.

This book was released on 2016-10-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
