The prevalence of hearing loss varies with age, affecting at least 25 percent of patients older than 50 years and more than 50 percent of those older than 80 years. Adolescents and young adults represent groups in which the prevalence of hearing loss is increasing and may therefore benefit from screening. If offered, screening can be performed periodically by asking the patient or family if the...
BACKGROUND It has been suggested that extended high-frequency audiometry (EHFA) might be more sensitive than conventional audiometry in detecting early signs of hearing impairment. However, this technique has not been adequately tested in an occupational environment. We therefore investigated the usefulness of this method in noise-exposed workers. METHODS We compared conventional frequency au...
Auditory Neuropathy coexisting with bilateral conductive hearing loss has not been reported so far .This case report highlights how the underlying Auditory Neuropathy can be unmasked by Speech Audiometry and that subsequently changes the entire management. Unlike Pure Tone Audiometry (PTA), Speech Audiometry is not necessarily done always for all patients, especially in developing countries and...
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...
BACKGROUND Screening for hearing loss in English children at entry to school (age 5-6 years) is usually by pure tone audiometry sweep undertaken by school nurses. This study aimed to compare the validity and screening rates of pure tone audiometry with impedance screening in these children. METHODS Two stage pure tone audiometry and impedance methods of screening were compared in 610 school e...
OBJECTIVE To characterize the findings of behavioral hearing assessment in HIV-positive individuals who received and did not receive antiretroviral treatment. METHODS This research was a cross-sectional study. The participants were 45 HIV-positive individuals (18 not exposed and 27 exposed to antiretroviral treatment) and 30 control-group individuals. All subjects completed an audiological ev...
BACKGROUND temporal ordering and temporal resolution. AIM to compare the performance of professional singers with that of well tuned and out of tune amateur singers in the pitch pattern test (PPT) and in the Random Gap Detection Test (RGDT). METHOD participants were 78 individuals, male and female, with ages ranging from 18 to 55 years. All of the participants were singers with normal heari...
OBJECTIVE This study investigated the reliability, accuracy, and time efficiency of automated hearing assessment using a computer-based telemedicine-compliant audiometer. MATERIALS AND METHODS Thirty normal-hearing subjects and eight hearing-impaired subjects were tested with pure-tone air conduction audiometry (125-8,000 Hz) in a manual and automated configuration in a counterbalanced manner...
Pure tone audiometry is the standard behavioral assessment of an individual’s hearing. The results of pure tone audiometry are recorded on a chart or form called an audiogram. In most cases a pure tone audiogram is easy to obtain and provides information about peripheral hearing acuity across the frequencies used in speech. It allows for a quick view of how well, or how poorly, an individual ca...
