Acoustic feedback is a major problem in openfit digital hearing aids, which significantly lowers the signal quality and limits the achievable maximum stable gain. Adaptive feedback cancellation (AFC) is a common and efficient approach, however, it introduces a biased estimate of the feedback path due to a high correlation between loudspeaker signal and the incoming signal, especially when the incoming signal is spectrally coloured, e.g., speech, music.

Hearing aids are important assistive devices for hearing rehabilitation. However, the cost of commonly available commercial hearing aids is often higher than the average monthly income of individuals in some developing countries. Therefore, there is a great need to locally produce cheaper, but still effective, hearing aids. The Thai-produced P02 hearing aid was designed to meet this requirement.

Hearing and vision impairments and the use of audio-visual aids are associated with cognitive decline in community-dwelling older people, but effects in long-term care facilities (LFCF) are unclear. We hypothesize that visual and hearing impairment are associated with cognitive decline and these relationships are mediated by using visual and hearing aids.

Ear (tympanostomy) tube (TT) placement is a common ambulatory surgery in children. Despite the commonality of this treatment, the long-term effects are unknown. The objective of this study was to determine the rate of permanent hearing loss, as measured by use of a rehabilitative hearing device.

Design of a digital hearing aid requires a set of filters that gives reasonable audiogram matching for the concerned type of hearing loss. This paper proposes the use of a variable bandwidth filter, using Farrow subfilters, for this purpose. The design of the variable bandwidth filter is carried out for a set of selected bandwidths. Each of these bands is frequency shifted and provided with sufficient magnitude gain, such that, the different bands combine to give a frequency response that closely matches the audiogram.

This book captures the experiences and voices of over 6,000 people who have received international assistance, observed the effects of aid efforts, or been involved in providing aid. Over time, across very different contexts and continents, people’s experiences with international aid efforts have been remarkably consistent. While there was a wide range of opinions on specifics, the authors were struck by the similarity in people’s descriptions of their interactions with the international aid system.

Psychiatric diagnosis requires doctors to make judgements based on their understanding of their patients’ mental states and emotional processes, and relate these to a ‘normal’ or ‘healthy standard’. Clearly this exercise is (at the very least) much more difficult where doctor and patient do not share a language, a set of concepts around the nature of mind and emotion, and an understanding of what behaviours fall within and without each others’ cultural norms.

When calling high in an organization to Chairpersons, Vice Presidents or Directors, it can take an hour of dialing before one of these people actually answers the phone. That means agents may only hear the voice of their desired contacts 8 or so times per day. These are very precious opportunities. If the salesperson’s behavior makes the call seem frivolous, or the only outcome is agreement that your company will send a $5 marketing piece, then you have your results. These results may even be permanent.

I became aware of the subjects of this book almost by accident. In the early 1980s, when HIV/AIDS so unexpectedly came upon the world, I was invited by that fine epidemiologist turned international civil servant, Dr Jonathan Mann, to join the World Health Organisation inaugural Global Commission on AIDS. This experience threw me into close contact with some of the leaders of medical science at the time, including Robert Gallo and Luc Montagnier, the two scientists who first isolated the virus that causes AIDS.

The Frame helps to address the questions, “How do we decide what information to include?” and “How do we ensure that consumers can understand the information about financial sharing policies and their personal information?” The testing quickly showed that consumers were relatively uninformed about financial privacy. They needed basic information about financial sharing practices to comprehend the disclosures that a GLBA notice is intended to convey.

With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main applications of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including perceptual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio.

IN THIS DAY and age of professionalism, many careers that years ago didn’t require much expertise now require not only formal training, but also some type of recognized certification. This is particularly true for many healthcare professions, including nursing assistant/nurse aide (NA). Prior to 1987, there were no standards in nursing homes and the quality of care was in question.As the public began to hear horrible stories in the media of the abuse and mistreatment of residents in nursing homes, the government decided to step in and take action.

Age-related hearing loss or presbycusis is mainly caused by changes in the inner ear. However, your genes and loud noises (such as from rock concerts or music headphones) may play a large role. Initially there is difficulty in hearing high-frequency sounds, such as someone talking. As hearing gets worse, it may become difficult to hear sounds at lower pitches. Hearing aids Telephone amplifiers and other assistive devices may be helpful. A cochlear implant (Surgery) may be recommended for certain women with very severe hearing loss.

Breath sounds have long been important indicators of respiratory health and disease. Acoustical monitoring of respiratory sounds has been used by researchers for various diagnostic purposes. A few decades ago, physicians relied on their hearing to detect any symptomatic signs in respiratory sounds of their patients. However, with the aid of computer technology and digital signal processing techniques in recent years, breath sound analysis has drawn much attention because of its diagnostic capabilities.

During the time we met as a Commission, tragedies such as the African famines, the leak at the pesticides factory at Bhopal, India, and the nuclear disaster at Chernobyl, USSR appeared to justify the grave predictions about the human future that were becoming commonplace during the mid-1980s. But at public hearings we held on five continents, we also heard from the individual victims of more chronic, widespread disasters: the debt crisis, stagnating aid to and investment in developing countries, falling commodity prices and falling personal incomes.
