Altogether 153 (60%) out of a sample of 253 people aged 70 years and over living in their own homes were found to have impaired hearing when tested by pure-tone audiometry. This is almost twice the prevalence found in all other studies, in which deafness was assessed clinically or by self-reporting. The prevalence of deafness increased with age. Evidence of organic brain syndrome (dementia), as...
Cystic fibrosis (CF) patients receive repeated courses of aminoglycoside therapy. These patients would consequently be expected to be more susceptible to cochleotoxicity, a recognized side effect with single courses of aminoglycoside therapy. The primary aim of this retrospective study was to establish the incidence and severity of auditory deficit in CF patients. Standard (0.25- to 8-kHz) and ...
OBJECTIVES To determine the prevalence of mild hearing loss and its association with academic performance among primary school children. PATIENTS AND METHODS A comparative cross sectional study was conducted on standard (grade) five school children in a state in Malaysia. Five schools were selected by using simple random sampling. There were three classes (A, B and C) of standard five in each...
This statement has been approved by the Council on Child and Adolescent Health. PEDIATRICS (ISSN 0031 4005). Copyright © 1987 by the American Academy of Pediatrics. screening by pure-tone audiometry be used as the primary method of detection of hearing loss in school children; (4) the impedance bridge not be used as a replacement for audiometnic screening, because it will not detect sensory neu...
The etiology of sensorineural hearing loss is multifactorial which makes the diagnosis a challenging exercise and often an unsolved mystery. Whilst pure tone audiometry is a mandatory investigation, others such as laboratory and radiology are based on clinical evaluation. This paper puts forward a protocol for the investigation for sensorineural hearing loss.
BACKGROUND We sought to examine hearing loss in a group from the Royal Australian Air Force who undertook fuel tank maintenance on F-111 aircraft, with exposure to formulations containing ototoxins, relative to two different comparison groups. METHODS Using pure-tone audiometry, hearing thresholds were assessed in 614 exposed personnel, 513 technical-trade comparisons (different base, same jo...
In order to preserve their operational effectiveness and ultimately their survival, military personnel must be able to detect important acoustic signals and maintain situational awareness. The possession of sufficient hearing ability to perform job-specific auditory tasks is defined as auditory fitness for duty (AFFD). Pure tone audiometry (PTA) is used to assess AFFD in the UK military; howeve...
INTRODUCTION The otoacoustic emission test is useful in monitoring hearing changes not yet detectable in pure-tone audiometry, as well as in monitoring cochlear damage caused by exposure to noise. OBJECTIVE To evaluate distortion product otoacoustic emissions in normal-hearing workers exposed to different occupational noise doses. MATERIALS AND METHOD This is a cohort prospective study perf...
OBJECTIVES To compare tinnitus patients who have normal hearing between 250 Hz and 8 kHz with normal controls with regard to the ability of each group to hear extended high-frequency pure tone thresholds. METHODS We enrolled 18 tinnitus patients, each of whom had a threshold of HL <25 dB and threshold differences of <10 dB between ears at frequencies of 250 and 500 Hz and 1, 2, 4, and 8 kHz. ...
AIM To determine the prevalence of hearing disorders in Singapore military conscripts and describe the profile of hearing loss and associated risk factors. METHODS Population-based descriptive analysis of randomised cohort of 818 Singapore military conscripts presenting for medical examination, using self-administered questionnaire and pure tone audiometry performed for both ears. Main outcom...
