In this article, current status of noise exposure in workplaces, trend of workers with noise-induced hearing loss (NIHL), and prevalence of NIHL in workers by industry and job category in Korea were reviewed. In addition, trends of research on the audiological effects such as hearing loss from noise and occupational hearing loss from non-noise in Korea were addressed through reports in industri...

BACKGROUND AND OBJECTIVES The auditory profile of a large number of persons with late onset auditory neuropathy spectrum disorder (ANSD) is recently described in the Indian context. The purpose of study was 1) to profile data on routine audiological parameters, cortical evoked potentials, and temporal processing, 2) to analyze the benefit from hearing aids for persons with ANSD, and 3) to under...

AIM to analyze the audiological profile of elderly patients seen in a clinic from an audiology school clinic in the city of Belo Horizonte. METHODS we studied all the charts from the patients who underwent audiologic assessment from April of 2004 and August of 2007 in an audiology clinic in the city of Belo Horizonte. RESULTS We studied the 313 audiological tests from patients 60 years of a...

Objective: Otosclerosis has long been a clinical, audiological and tympanometric diagnosis. The definitive role and value of imaging is yet unclear in the clinical practice. In this work we aimed to study the temporal bone density using CT scan in patients clinically diagnosed as otosclerosis, not only to ascertain the value of CT scan, but also to study the correlation between the bone density...

It is well known that communication in noisy environments with reverberation present is a difficult problem to solve, particularly for the hearing-impaired listener. Two-microphone noise cancelling using an LMS adaptive filter in real time was used to process speech recorded in the presence of speech-spectrum noise at six different signal-to-noise ratios, -8, -4, 0, 4, 8, and 12 dB. Twelve norm...

PURPOSE To evaluate the temporal processing of popular singers who do or do not play a musical instrument. METHODS The study population comprised 30 popular band singers. Of them, 15 play a musical instrument (G1) and 15 do them do not play a musical instrument (G2). All of them were submitted to basic audiological evaluation and temporal processing tests: test of frequency standard (TFS) and...

Stopping rules for ascending audiological test procedures were evaluated by Monte Carlo simulation. The stopping rules differed in the minimum number of responses required at a level, whether these responses occurred on half or a majority of the ascending series, and whether all or only the most recent ascending series were considered. For all procedures, shallow psychometric function slopes yi...

Williams or Williams -Beuren Syndrome (WS) is a very rare syndrome associated with a microdeletion on chromosome 7q11.23. Williams syndrome is characterized by multiple congenital anomalies including distinctive facial features, cardiovascular anomalies, neurodevelopmental delay and mental retardation. Sensorineural hearing loss is not reported very often in WS patients. The purpose of the stud...

Tinnitus is a symptom that affects a great number of patients. Its diagnosis, treatment, and follow-up are difficult, owing to its subjectivity. The authors propose the use of distortion product otoacoustic emissions (DPOAEs) in tinnitus evaluation. They studied three groups: controls, having no complaint of tinnitus and normal hearing; group 1, presenting tinnitus and normal audiometry; and gr...

BACKGROUND Vertigo is a common and diagnostic challenge faced by clinicians. OBJECTIVE This article discusses the assessment of patients with vertigo. DISCUSSION The clinical assessment aims to: establish the presence of true vertigo, differentiate between vertigo of central or peripheral origins, and to evaluate the need for urgent investigations and referrals. Peripheral causes of vertigo...
