UNLABELLED One of the most criticized points in tinnitus clinical studies arise from the lack of consensus about measurement methods. AIM To evaluate the correlation between audiometric thresholds, pitch matching (PM), minimum masking level (MML), Tinnitus Handicap Inventory (THI) and the Beck Depression Inventory (BDI) in tinnitus patients. STUDY DESIGN Prospective, cross-sectional. MATE...

DESIGN A retrospective medical record review of evoked potential and audiometric data were used to determine the accuracy with which click-evoked and tone burst-evoked auditory brain stem response (ABR) thresholds predict pure-tone audiometric thresholds. METHODS The medical records were reviewed of a consecutive group of patients who were referred for ABR testing for audiometric purposes ove...

The early fitting of infants with hearing aids relies largely on the verification of amplification characteristics using simulated real ear measurements (REM) that are matched to prescription targets derived from audiometric thresholds. The audibility of different parts of the speech spectrum can be inferred from the audiometric thresholds and the estimated applied gain, and is expressed as the...

Brain magnetic resonance imaging (MRI) is the gold standard for diagnosing a vestibular schwannoma (VS). The prevalence of VS ranges from 0.02-2.4%; the incidence is 20 per million per year. This case report describes two cases of VS identified on brain MRIs that were not related to the purpose of the MRI examination. A literature search was performed to find existing audiometric-based protocol...

AIM To co-relate the use of hormonal contraceptives with positive Auditory and Vestibular alterations. METHODS medical history taking, audiometric test and vestibular test was applied to 60 women between the ages of 14 and 35 years old, and 30 of these women are on oral hormonal contraceptive consisting of Estrogen and Progesterone (risk group), for 6 months or more, that had no Auditory or V...

Audiometric hearing tests were conducted at the Mayo Clinic in Rochester at the beginning of the 1930s. The list price for one of its audiometers at that time was 3,500 dollars, which translates into approximately 37,000 dollars in 2003 currency. Physicians and residents in training were responsible for conducting hearing tests in the 1930s and 1940s. In the early 1940s a registered nurse was t...

Audiometric hearing deficits are a common symptom of age-related hearing loss (ARHL), as are specific histopathological changes in the cochlea; however, very little data have been collected in non-human primates. To examine this relationship further, we collected auditory brainstem responses (ABRs) from rhesus monkeys spanning in age from 10 to 35 years old, and examined four different morpholo...

UNLABELLED Exposure to occupational noise may cause injuries to the inner ear, and the distortion product otoacoustic emissions (DPOAE) may identify initial auditory alterations, thus assisting NIHL early diagnosis. AIM The goal of this study was to evaluate DPOAE as a method to diagnose early physiopathological alterations caused by occupational noise exposure. STUDY DESIGN Transversal. ...

Speech audiometric measures were carried out on 981 patients using a computer-based system that permitted a comparison between two modes of signal presentation, manual and automatic. The manual mode, designed to simulate the pace of live-voice testing, allowed the presentation of speech signals at a rate dictated by the patient's response. The automatic mode, designed to simulate tape-player te...

The objectives of this study were to review the application and feasibility of providing screening, diagnosis, medical and surgical treatment for patients with ear discharge by setting a mobile hospital in rural India. The study was retrospective. The study involved collection of data from 1992 to 2005 from patients with ear diseases. The number of patients operated on for ear conditions and th...
