BACKGROUND/AIM A more recent method, the auditory steady-state response (ASSR), has become more and more important test method due to difference that was found in previous investigations between hearing thresholds determined by the ASSR and the pure-tone audiometry (PTA). The aim of this study was to evaluate the reliability of the ASSR in determining the frequency specific hearing thresholds b...

The accuracy of five bedside hearing tests was evaluated in 107 consecutive adults, using pure-tone audiometry as the standard reference. Bedside tests had poor sensitivity (< or =0.60), relatively good specificity (> or =0.74), and variable positive predictive value (0.24 to 1.0) for detecting hearing loss. Sensitivity improved when bedside tests were combined with case history. The diagnostic...

OBJECTIVE To investigate the validity of diagnostic pure-tone audiometry in a natural environment using a computer-operated audiometer with insert earphones covered by circumaural earcups incorporating real-time monitoring of environmental noise. DESIGN A within-subject repeated measures design was employed to compare air (250 to 8000 Hz) and bone (250 to 4000 Hz) conduction pure-tone thresho...

the aim of the current study is to investigate hearing function in patients with allergic rhinitis. fifty-eight patients with positive skin prick test (group 1) (116 ears) and    31 subjects with negative skin prick test (62 ears) as group 2 were included. pure tone audiometry at 250,500, 1000, 2000, 4000 and 8000 hz and immittance measures, including tympanometry and acoustic reflex tests, wer...

multiple sclerosis (ms) is a demyelinating disorder of central nervous system. it involves 8th cranial nerve and its central nuclei and is an uncommon cause of the sensorineural hearing loss. for determining the prevalence of hearing loss (hl) especially retrocochlear type in ms, a cross-sectional study was designed using pure-tone audiometry (pta), otoacustic emissions (oaes), auditory brainst...

introduction: hearing loss is one of the most common occupational diseases. in most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise.  in this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise.   materials and met...

OBJECTIVE To assess the prevalence of hearing impairment in siblings of children with profound to total hearing impairment. METHOD Two hundred and twenty siblings of children at a deaf school in Karachi completed the screening program. This consisted of a questionnaire and pure tone audiometry. RESULTS One out of three (73 siblings) had a threshold of 25 dB or greater in their better ear. I...

BACKGROUND Hearing loss is the most common sensory deficit in elderly patients, and is often under-recognised and poorly managed. It is essential for all clinicians to have awareness and knowledge in this field to enable the institution of early and appropriate care. OBJECTIVE The goal of this article is to review the causes, diagnosis and management of hearing loss as it applies to elderly p...
