Computer assisted audiometric evaluation system
… data are acquired and displayed on a dynamic audiogram and speech discrimination gram respectively. This data may be stored and later retrieved from a patient data base. Further audiometric tests may be incorporated at a later stage.

A distortion product otoacoustic emissions (DPOAE) assessment of cochlear function in tinnitus subjects with normal hearing sensitivity
… non-tinnitus subjects (matched by age, sex, and audiogram) across a broad range of frequencies and intensities. DPOAE magnitudes were measured for at least 52 frequencies (500 Hz <f2 5 8 kHz, with f2ff=1.2) and nine intensities (20 dB < L2 5 60 dB, with L, = 39 + 0.4L2) in each ear. Further, this …

Hearing Sensitivity and the Effect of Sound Exposure on the Axolotl (Ambystoma Mexicanum)
… 2, 3, 4, and 6 kHz) in order to produce baseline audiograms of underwater pressure sensitivity. Individuals were then subjected to a 48-hour, 150 Hz sound exposure at approximately 170 dB (re 1 μPa). AEPs were then performed to measure hearing thresholds immediately after sound exposure and at 2, …

Non-Invasive Intracranial Pressure Method and Monitor
… if of sufficient intensity, resulting in an eye audiogram similar in degree to that obtained conventionally by bone conduction on the mastoid or forehead. The literature is suggestive that there is no positive correlation between IOP and ICP in terms of pressure, but there is a correlation when …

Middle ear pressure gain and cochlear input impedance in the chinchilla
… This quantity was a good predictor for the audiogram at frequencies below 1 kHz.

Pitch, loudness and frequency selectivity in low-frequency hearing loss
… on the hearing fluctuations than the occasional audiogram used today and constitute an approach to quantify the fluctuations. Quantifications could potentially be used to define disease subgroups and to evaluate treatments. This thesis aims to introduce 'home audiometry' to monitor hearing …

Factors affecting speech recognition in noise and hearing loss in adults with a wide variety of auditory capabilities
… increases<br/>and the importance of the audiogram decreases as the degree of hearing loss increases, provided<br/>speech is presented at audible levels. However, for all degrees of hearing impairment included<br/>in the study, prediction based solely on hearing thresholds was not much …

Hearing assessment aboard the International Space Station
This study undertakes to refine the understanding of the accuracy of a novel PC-based hearing assessment utilized aboard the International Space Station. During the design and construction of the ISS, time and funding constraints led to engineering compromise related to acoustics, resulting in a …

The Effect of Cochlear Dysfunction on Central Auditory Speech Test Performance
… scores of the cochlear impaired subject, (d) the audiogram configuration, and (e) the presentation mode of the test.</p> <p>The level of performance on the central auditory speech test battery is related to the level of the auditory site for which the tests are intended. The level of performance …

The Role of Low Tone Average in the Diagnosis of Meniere's Disease
… as well as interpreting, the results. Audiograms are performed routinely in evaluating a patient with suspected MD. Audiograms in MD patients, especially early in the disease, show a characteristic low-frequency loss. This study sought to explore the low-frequency loss as yet another …

Messung von sechs verschiedenen modernen digitalen Hörgeräten mit fünf Audiogrammen am 2 cm³- Kuppler
… wurden mit fünf verschiedenen Tonschwellenaudiogrammen mit Angabe der Unbehaglichkeitsschwelle programmiert und nach IEC-118 am 2ccm- Kuppler gemessen. Untersucht wurden der Frequenzgang, die Signalverstärkung, das äquivalente Eigenrauschen und die Ein- und Ausschwingzeiten der Hörgeräte. …
