BACKGROUND AND OBJECTIVES Increases in older aged populations and exposure to complicated noise environments have increased the number of hearing-impaired patients, creating greater demands for hearing aids. We have assessed the reasons that individuals rejected wearing and returned properly prescribed hearing aids, as well as differences in individual factors between younger and elderly adults...

BACKGROUND Approximately 2-4% of newborns with perinatal risk factors present with hearing loss. Our aim was to analyze the effect of hearing aid use on auditory function evaluated based on otoacoustic emissions (OAEs), auditory brain responses (ABRs) and auditory steady state responses (ASSRs) in infants with perinatal brain injury and profound hearing loss. METHODOLOGY/PRINCIPAL FINDINGS A ...

Recognizing the inherent weakness of the conventional hearing aid, we have developed a totally new design for hearing aids utilizing infrared (IR) light transmission. The hearing aid transmits the auditory message not as an acoustic wave, but as an infrared light beam. The invisible light beam carries the signal directly from a microphone near the speaker to the listener without any appreciable...

This paper reports the development of the Profile of Hearing Aid Performance (PHAP), a 66-item self-administered inventory that quantifies performance with a hearing aid in everyday life using both seven-score and four-score profiles. The profiles assess experience with amplification in terms of speech communication in three types of listening situations and in terms of reactions to amplified e...

OBJECTIVE To determine the cost-effectiveness of hearing-aid fitting. DESIGN Cost-effectiveness analysis using a Markov model based on aggregate data and results from a prospective intervention study. SETTING The cost-effectiveness study was based in the general community. The prospective study was hospital based, as 85% of the first-time hearing-aid users attend a hospital in the process o...

Hearing aids are devices used by hearing impaired people to compensate hearing losses. Digital hearing aids are better in performance over the analog hearing aids, since analog hearing aids work as amplifier. Digital hearing aids are programmable to adjust the gain value, enhance signal to noise ratio, reduction in noise, feedback cancellation etc . In the present work, study of digital hearing...

stated that we are in the age of outcome measures; these measures are essential in the assessment of hearing aid efficacy. While numerous efforts have been made to predict hearing aid outcome, an accurate method of predicting how people will utilize their hearing aids does not exist. Furthermore, it is not known why some individuals are better hearing aid users than others. The research we have...

Hearing aid is an electronic device fitted to the ear and designed amplify deliver sound ear. Upon fitting a hearing aid, patients are required make earmold impression material for fixation based on patient's personal preference, shape texture of

OBJECTIVES This study aims to evaluate the communication problems of elderly before and after using hearing aids. PATIENTS AND METHODS Thirty hearing aid users and 10 normal hearing control subjects with their relatives were enrolled in the study. Hearing aid users were divided into three subgroups based on the duration of use. Self Assessment of Communication (SAC) and Significant Other Asse...
