BACKGROUND This study determined the accuracy of pure tone air conduction (AC) thresholds obtained using a synchronous telemedicine approach without a sound booth in a rural South African community. The global need for increased hearing healthcare currently far exceeds the capacity for delivering these services, especially in developing countries. A tele-audiology approach using a portable diag...

Noise is usually defined either unwanted sound or sound that is harmful to the hearing. Earlier studies have shown that musicians are exposed to sound levels that can be harmful to hearing, and thus music can be considered as noise. Studies have also shown that musicians have hearing problems due to prolonged music exposure. This is also the case among classical musicians. According to the new ...

PURPOSE The purpose of this case-control study was to determine whether long-term ultrasonic noise exposure via the dental office environment is related to dental hygienists' hearing status. METHODS Registered dental hygienists (N = 698) who live in the Hampton Roads areas of Virginia were mailed a Dental Hygiene Work History Questionnaire to determine who would meet the inclusion criteria an...

INTRODUCTION To assess the association between sensory and cognitive function, and the potential influence of visual function on cognitive function assessment, in a sample of clients accessing aged care services. MATERIALS AND METHODS We recruited 260 non-institutionalised, frail, older individuals who sought aged care services. Visual acuity was assessed using a LogMAR chart and hearing func...

A masking dilemma occurs when energy from a non-test ear crosses over the head to a test ear. In cases of bilateral atresia, obtaining thresholds on the poorer ear is problematic. Near threshold, however, sufficient ear-bone isolation exists to test with validity but not so much above threshold, even for the ultra-high (> 10 kHz) frequencies. This aspect of the bone audiogram should not be over...

Loudness of different sounds was measured in order to evaluate Zwicker’s and Moore’s loudness models (published in Acta Acustica [3] and in the J. Audio. Eng. Soc. [4]). The test signals were synthesized bands of noise and environmental sounds. For synthesized noises, Zwicker’s model fits highly well with subjective results, it is a little bit closer to the data than Moore’s. For environmental ...

BACKGROUND Wax in ear canal causes a sizeable burden on resources of health services to a country. AIM The magnitude of impacted wax, its effect in a survey and cost of managing this problem were reviewed in 2002. SETTINGS AND DESIGNS A study was conducted during 1996 to estimate the magnitude and causes of hearing impairment and ear diseases in Oman. The authors further reviewed the data o...

Background: Bilateral anterior nasal packing is often done after septal surgery for hemostatic reasons and mechanical splinting. It has been suggested that following a frequent cause of short term eustachian tube dysfunction such as ear fullness mild pain.
 Objectives: To evaluate the effect on middle pressure.
 Methods: For this prospective, longitudinal study, ninety-two (92) patien...
