Pure Tone Audiometry
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...
متن کاملCorrelations between audiogram and objective hearing tests in sensorineural hearing loss.
Owing to its subjective nature, behavioral pure-tone audiometry often is an unreliable testing method in uncooperative subjects, and assessing the true hearing threshold becomes difficult. In such cases, objective tests are used for hearing-threshold determination (i.e., auditory brainstem evoked potentials [ABEP] and frequency-specific auditory evoked potentials: slow negative response at 10 m...
متن کاملSmartphone Based Audiometric Test for Confirming the Level of Hearing; Is It Useable in Underserved Areas?
OBJECTIVE To determine the hearing levels of participants of a randomized group using a smartphone hearing application and to compare these results with the results from a pure-tone audiogram. MATERIALS AND METHODS A heterogenous group consisting of both normal-hearing and hearing-impaired participants were included in this study. Pure-tone audiogram thresholds were measured from 250 Hz to 80...

Background: Cortical Evoked Response Audiometry (CERA) refers to prediction of behavioral pure-tone thresholds (500-4000 Hz) obtained by recording the N1-P2 complex of auditory long latency responses. CERA is the preferred method for frequency–specific estimation of audiogram in conscious adults and older children. CERA has an increased accuracy of determination of the hearing thresholds of ale...
متن کاملHearing Ability with Age in Northern European Women: A New Web-Based Approach to Genetic Studies
Age-related hearing impairment (ARHI) affects 25-40% of individuals over the age of 65. Despite the high prevalence of this complex trait, ARHI is still poorly understood. We hypothesized that variance in hearing ability with age is largely determined by genetic factors. We collected audiologic data on females of Northern European ancestry and compared different audiogram representations. A web...
