Test/retest reliability of distortion-product and transiently evoked otoacoustic emissions
fluid or infection behind the eardrum or a perforation of the eardrum), and proper otoacoustic emissions
may not be recorded.
Factors affecting sensitivity of distortion-product otoacoustic emissions
to ototoxic hearing loss.
The value of otoacoustic emissions
in investigations of noise damage.
In earlier studies, McFadden and his colleagues found that women with twin brothers have quieter otoacoustic emissions
Abbreviations: C&P = Compensation and Pension, CAP = central auditory processing, CAPD = central auditory processing disorder, dBHL = decibels hearing loss, DPOAE = distortion product otoacoustic emission
, IED = improvised explosive device, NSI = Neurobehavioral Symptom Inventory, OAE = otoacoustic emission
, RPG = rocket-propelled grenade, SD = standard deviation, TBI = traumatic brain injury, VA = Department of Veterans Affairs, VHA = Veterans Health Administration.
To detect otoacoustic emissions
, researchers insert a miniature probe -- which looks somewhat like a hearing aid and contains a sound source and a sensitive microphone -- into the outer ear canal.
Distortion Product Otoacoustic Emissions
Figure 1 shows DP-grams obtained from the untreated control group at baseline and at time points equivalent to those for experimental subjects.
A female dizygotic twin with a twin brother, compared with a female dizygotic twin with a twin sister, has fewer spontaneous otoacoustic emissions
(clicking sounds generated by the ear) (McFadden 1993) and less craniofacial symmetry (Boklage 1985), and exhibits more risk-taking behavior (Resnick et al.
