Distortion product otoacoustic emissions in normally hearing subjects.
The finding of active function by the outer hair cells for sound processing prior to neural transduction in the inner hair cells represents the basic mechanism for the generation of Otoacoustic Emissions in the cochlea. Among them the so-called Distortion Product Otoacoustic Emissions represent a tool for an in depth knowledge of the Organ of Corti micromechanics, more advantageous than others,...
متن کاملRisk factors for distortion product otoacoustic emissions in young men with normal hearing.
The purpose of this study was to evaluate the possible effects of risk factors on distortion product otoacoustic emissions (DPOAEs) in young adult men with normal hearing. Four hundred thirty-six United States Marine recruit men (mean age = 19.2 years +/- 1.8 years; age range = 17-29 years) participated in this study. Questionnaires were given to each recruit to obtain demographic data and hist...
متن کاملOtoacoustic emissions from normal-hearing and hearing-impaired subjects: distortion product responses.
Distortion product otoacoustic emissions (DPOAE) were measured in normal-hearing and hearing-impaired human subjects. Analyses based on decision theory were used to evaluate DPOAE test performance. Specifically, relative operating characteristic (ROC) curves were constructed and the areas under these curves were used to estimate the extent to which normal and impaired ears could be correctly id...
متن کاملHigh-frequency hearing influences lower-frequency distortion-product otoacoustic emissions.
OBJECTIVES The primary goal of this study was to test the ability of 2f1-f2 distortion-product otoacoustic emissions (DPOAEs) to detect reduced cochlear function in the presence of normal behavioral sensitivity. DESIGN A prospective study was performed in normal-hearing young adults using simple and complex regression analyses to clarify the relationship between ultra-high frequency (UHF) hea...
متن کاملInsights into elevated distortion product otoacoustic emissions in sickle cell disease: comparisons of hydroxyurea-treated and non-treated young children.
Distortion product otoacoustic emissions (DPOAEs) were examined in 15 normal-hearing African-American children between the ages of 6 and 14 years with homozygous sickle cell disease (SCD), who were on a regimen of hydroxyurea (HDU), a drug that reduces inflammatory processes and symptoms of SCD; a matched group of 15 African-American children with homozygous SCD not on HDU; and 15 African-Ameri...
