UNLABELLED Despite its high prevalence in the aged, hearing loss has been poorly investigated. Audiometry is the gold standard for evaluation of hearing loss, but large-scale use of the procedure involves operational difficulties. Thus, self-report may be an alternative. AIM To determine if a single global question is valid for use in epidemiologic research. STUDY DESIGN Systematic review. ...
showed significant changes in frequencies >8 kHz that were not detected with the routine pure tone audiometry and distortion product otoacoustic emission audiodiagnostic tests. In conclusion, although the idea of such studies about the otoprotective effect of intratympanic injections against cisplatininduced ototoxicity seems magnificent and deserves more modifications, a careful revision in ev...
Tympanometric measures were obtained in 1240 adults (2147 ears) ranging in age from 48 to 90 years. All subjects reported a negative history of otic disease, passed an otoscopic examination, and did not present a significant air-bone gap based on pure-tone audiometry. Relative to findings for younger adults, tympanometric measures for older adults in the present study showed greater variability...
Different studies have demonstrated that solvents may induce auditory damage. It has been suggested that part of this damage may be localised in central auditory pathways. The present study aimed to investigate possible auditory processing disorders related to solvent exposure. Thirty solvent-exposed workers and 30 gender-, age- and educational level-matched control subjects were selected to pa...
During the period from 1980 to 1984, 50 cases (98 ears) of psychogenic deafness in children have been examined at the hearing clinic of the Department of Otolaryngology. All were school children aged from 6 to 15 years. They were classified into 3 groups (A, B, C) and their audiological, psychological, opthalmological findings and progress were reported. Cases of A group complained of deafness ...
BACKGROUND An estimated 360 million people have a disabling hearing impairment globally, the vast majority of whom live in low- and middle-income countries (LMICs). Early identification through screening is important to negate the negative effects of untreated hearing impairment. Substantial barriers exist in screening for hearing impairment in LMICs, such as the requirement for skilled hearing...
Through pure-tone audiometry, we studied the course of hearing recovery in 24 ears of 20 men (ages 18-48 years) who had acute acoustic sensorineural hearing loss (ASHL). All subjects were members of the Japanese Self-Defense Force. The hearing level in 5 ears returned to normal, the hearing level of 13 ears recovered but was not within the normal range, and the hearing level of 6 ears was uncha...
INTRODUCTION Tinnitus is one of the symptoms that affects individuals suffering from noise induced hearing loss. This condition can be disabling, leading the affected individual to turn away from work. OBJECTIVE This literature review aims to analyze the possible association between gender and tinnitus pitch and loudness, the degree of hearing loss and the frequencies affected in subjects wit...
OBJECTIVE Evaluation of pure-tone audiometry (PTA) in hearing screening of a population with mild to profound intellectual disability (ID). DESIGN PTA was performed at six frequencies at the screening level 20 dB HL. Referral criteria were threshold levels ≥ 25 dB HL at two or more frequencies for one ear or both. STUDY SAMPLE 1478 participants aged 7-91 years were included. RESULTS 1470 ...
A cross sectional survey of 581 TA personnel from Wales, the Midlands and Scotland was performed. The aim was to determine their hearing levels, to attempt to relate any degree of noise induced hearing loss detected with military, occupational and leisure noise and to make recommendations to improve the existing Army Hearing Conservation Programme. Each subject answered a questionnaire, had a c...
