The ear molds and shells of hearing devices are generally designed using impressions. Computed tomography (CT) can provide information concerning structure, which be utilized in computer-aided design to create devices. This study aimed compare the differences either impressions or CT images. chip a cartilage conduction (CC) device was based on impression images patients with aural atresia. Thre...

Ear modeling can significantly improve sound signal processing and the design of hearing devices. Ear models based on mechanics and neural phenomenology of the inner ear (cochlea) form a class of nonlinear nonlocal dispersive partial differential equations (PDEs). These PDEs capture the essential nonlinear phenomena in hearing, such as combination frequency generation, compression, and suppress...

European Community (EC) legislation requires identification and registration of bovine, ovine, caprine and porcine animals. For intra-Community trade, bovine animals must be accompanied by a passport and the required health certificate, and identified by a tag on each ear. The principles of active identification of bovine animals (by ear tags) and of ovine, caprine and porcine animals (by ear t...

Most binaural hearing aid systems have separate processing for each ear. Collaborative processing allows the left and right hearing aids to share information and resources. In this paper, collaborative processing is used to take advantage of head shadow effects to improve Voice Activity Detection (VAD). We emphasize here that while a variety of improvements in VAD and speech enhancement are pos...

The subjective benefit of middle ear implantation was studied in a group of 23 hearing-impaired patients who could not use conventional hearing aids owing to severe chronic external otitis. Changes in hearing disability (Abbreviated Profile of Hearing Aid Benefit [APHAB]) and changes in quality of life (Glasgow Benefit Inventory [GBI]) were determined. Mean benefit value on the APHAB for the su...

Ninety-four unilateral CI patients with bimodal listening experience (CI plus HA in contralateral ear) completed a questionnaire that focused on attitudes toward hearing aid use postimplantation, patterns of usage, and perceived bimodal benefits in daily life. Eighty participants continued HA use and 14 discontinued HA use at the time of the questionnaire. Participant responses provided useful ...

BACKGROUND Obstructive sleep apnea (OSA) is a growing problem affecting millions of people in the United States. The prevalence of OSA has risen drastically in the past few decades concurrently with the increasing prevalence of obesity. Subsequently, there has been an ever-increasing rise in the use of continuous positive airway pressure (CPAP) devices. While using CPAP devices may lead to many...

Introduction: Noise pollution is an important health hazard in modern times and traffic policemen automobile drivers are exposed to unregulated vehicular noise. This study aims estimate the exposure levels from noise for assess their awareness regarding use of prevention measures. Methods: An analytical cross-sectional was carried out comprising control group with 121 people each group. Sound l...
