This book was released on 2007-12-20 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cochlea does not just pick up sound, it also produces sounds of low intensity called Otoacoustic Emissions (OAEs). Sounds produced by healthy ears – either spontaneously or in response to stimuli - allow researchers and clinicians to study hearing and cochlear function noninvasively in both animals and humans. This book presents the first serious review of the biological basis of these otoacoustic emissions.

This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The cochlea produces recordable acoustic energy (otoacoustic emissions). These otoacoustic emissions occur spontaneously or can be evoked. Distortion-product otoacoustic emissions (DPOAEs) are produced by the intermodulation between the primary stimulus tones (f2 > f1) and occur at frequencies not present in the evoking acoustic stimuli. The 2f1-f2 DPOAE is well characterized for frequencies less than 8 kHz in humans; however, most basilar membrane measurements in animals have been made at higher frequencies. Thus, DPOAE measurements were extended to the higher frequency range of human hearing. High-frequency DPOAEs were characterized by how the DPOAE level varied with primary frequency separations (f2/f1) and stimulus levels and how the group delay estimate of the DPOAE varied with primary frequency. It was concluded that high-frequency DPOAEs continued the patterns seen for low-frequency DPOAEs, indicating that high-frequency DPOAEs are the result of the same biological process responsible for low-frequency DPOAEs.

Book excerpt: (Uncorrected OCR) Abstract of dissertation entitled Test-retest Reliability of Distortion Product Otoacoustic Emissions in the High Frequency Range submitted by NG, Hoi-Yee Iris for the degree of Master of Science in Audiology at the University of Hong Kong in May 2002 In the current research study, distortion product otoacoustic emissions (DPOAEs) were measured in 35 young Chinese adults (61 ears) with normal audiometric thresholds using an IL096 OAE system with the default DP-gram protocols as well as user-defined DP spectrum protocols in the high frequency range. Two series of retest were conducted 20 minutes and an average of 15 days later, and the resolution setting for the DP-gram measurements was varied between 1 to 8 points per octave in each test series. Transient evoked otoacoustic emissions (TEOAEs) were also recorded in each test series for comparison purposes. Test-retest partial correlation and standard error of measurement (SEM) were computed to reflect the test-retest reliability of the OAE amplitudes, noise floor and signal-to-noise ratio. Results suggested that OAE amplitudes in the default frequency range (1 to 6 kHz) between test and retest were highly correlated with an average correlation coefficient of 0.85 and SEM was found to be an average of 2.4 dB, while signal-to-noise ratio and noise floor yielded lower correlation coefficients and higher SEMs. OAE amplitudes in the higher frequency range of 6.5 to 7 kHz were also significantly correlated between test and retest (correlation coefficient ranged from 0.74 to 0.80) with SEM from 2.7 to 3.5 dB. Yet DPOAEs at 8 kHz were present with a positive signal-to-noise ratio in only one-third of ears, were less test-retest correlated, and the amplitude revealed a high SEM of 5 dB. No apparent difference was demonstrated among various resolution settings and between short- and long- term retest. This implies that DPOAEs in the high frequency range (6.5 to 7 kHz) could be a potential clinical tool for mo.
Download or read book Frequency Specificity of Contralateral Suppression of Distortion Product Otoacoustic Emissions written by Lisa Arnelle Ross and published by . This book was released on 2013 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frequency specificity of the contralateral suppression effect as demonstrated in DPOAEs was measured in 20 adult participants using contralateral stimuli consisting of white noise, and. 5, 1, 2, and 3 kHz tones with presentation levels of 40, 50, and 60 dB SPL. A significant suppression effect was found with white noise in the low frequencies (1.125 to 2.531 kHz) as well as higher frequencies (5.062 to 6.328 kHz). While not reaching a level of significance, 2 and 3 kHz demonstrated a similar suppression as white noise in the higher frequencies (5.062 to 6.328 kHz) and a non-significant enhancement effect was observed in the low frequencies (2.015 to 2. 812 kHz). Future studies of contralateral suppression should examine BBN with various high frequency cut offs in order to more fully examine these phenomenon.
