Effects of intense sound exposure on spontaneous otoacoustic emissions

Effects of spontaneous otoacoustic emissions on frequency discrimination

On the heritability of spontaneous otoacoustic emissions: A twins study.

Spontaneous otoacoustic emissions (SOAEs) were measured in human monozygotic (MZ) and dizygotic (DZ) twins and in a sample of non-twins. The number of SOAEs exhibited was more highly correlated in MZ co-twins than in same-sex DZ co-twins. Model-fitting to the correlations suggested that about three-quarters of the individual variation in the expression of SOAEs is attributable to genes. There w...

The effects of aging on evoked otoacoustic emissions and efferent suppression of transient evoked otoacoustic emissions.

OBJECTIVE There is still controversy regarding the effects of aging on evoked otoacoustic emissions (EOAEs), as well as on the efferent system measured by contralateral acoustic stimulation of EOAEs. The purpose of this study was to investigate the deterioration in EOAEs and efferent suppression (ES) in a representative sample statistically controlling for the differences in hearing thresholds....

Effects of salicylates and aminoglycosides on spontaneous otoacoustic emissions in the Tokay gecko.

The high sensitivity and sharp frequency discrimination of hearing depend on mechanical amplification in the cochlea. To explore the basis of this active process, we examined the pharmacological sensitivity of spontaneous otoacoustic emissions (SOAEs) in a lizard, the Tokay gecko. In a quiet environment, each ear produced a complex but stable pattern of emissions. These SOAEs were reversibly mo...

assessment of the effects of different sound pressure levels on distortion product otoacoustic emissions (dpoaes) in rats

excessive exposure to noise can lead to noise-induced hearing loss. otoacoustic emissions affect the microscopic biomechanical activities of healthy outer hair cells. the present study aimed at assessing the influence of various sound pressure levels on distortion product otoacoustic emissions (dpoaes) in rats. to this end, 27 adult male rats with an age range of 3 to 4 months and a weight of 2...
