Journal ArticleDOI
The relationship between distortion product otoacoustic emissions and extended high-frequency audiometry in tinnitus patients. Part 1: Normally hearing patients with unilateral tinnitus

TL;DR: Hearing thresholds in tinnitus ears with normal hearing sensitivity in the conventional range were higher in the EHF region than those in non-tinnitus control subjects, implying that cochlear damage in the basal region may result in the perception of tinnitis.
Journal ArticleDOI
Identification of otoacoustic emissions components by means of adaptive approximations.
TL;DR: The analysis of OAE's energy density distributions in time-frequency space revealed that click responses can be considered as linear superpositions of responses to tone bursts, which opens new perspectives in studying the fine structure of the OAE and testing of the theoretical models.
Journal ArticleDOI
Time–frequency analysis of transiently evoked otoacoustic emissions of subjects exposed to noise
TL;DR: Good distinction between the two datasets was achieved in all investigated frequency bands when amplitude was used as a discrimination parameter, and latency was affected in frequency bands starting at 2000 Hz, while the time-span parameter associated with the duration of the waveform was less influenced by noise.
Journal ArticleDOI
Satisfaction With Cochlear Implants in Postlingually Deaf Adults and Its Nonaudiological Predictors: Psychological Distress, Coping Strategies, and Self-Esteem.
TL;DR: The results show that psychological factors—self-esteem, distress, and coping strategies—are important for CI satisfaction in postlingually deaf CI users.
Journal ArticleDOI

TL;DR: This paper makes the case that it is important to include central auditory processing disorder (CAPD) tests in the hearing screening of school-age children, and evaluates the usefulness of the dichotic digits test (DDT).
