DESIGN A retrospective medical record review of evoked potential and audiometric data were used to determine the accuracy with which click-evoked and tone burst-evoked auditory brain stem response (ABR) thresholds predict pure-tone audiometric thresholds. METHODS The medical records were reviewed of a consecutive group of patients who were referred for ABR testing for audiometric purposes ove...

introduction: in order to achieve a higher success rate for tympanoplasty, different techniques have been developed, and a wide variety of grafting materials have been developed. one of the techniques currently receiving considerable attention involves not lifting the remaining of eardrum from the malleus and embedding the graft underneath in order to repair the eardrum correctly in its origina...

The long term goal of this international cooperative research program is to investigate behavioral reactions and the sound exposures required to elicit them of herring, killer whales, pilot whales and sperm whales to Low Frequency Active Sonar (LFAS) and Mid Frequency Active Sonar (MFAS) signals, in order to establish safety limits for sonar operations for these species. The hypothesis that we ...

This study examined the association between ultrahigh-frequency (UHF) hearing sensitivity and distortion-product otoacoustic emission (DPOAE) levels at conventional frequencies. Behavioral thresholds were measured from 2 through 16 kHz, and DPOAE levels were measured at discrete f2 frequencies between 2 through 8 kHz in 553 young normal-hearing adult male participants. A DPOAE frequency sweep w...

In the elderly, the results of central auditory pathways behavioral assessments are considered to be difficult to read because of the possible interference of peripheral auditory pathway involvement. Aim: Assess the efficacy of the central auditory function in elderly patients who do not complain of hearing. Materials and Methods: Case study involving 40 individuals within the age range of 60 t...

We had a unique opportunity to investigate the auditory processing abilities of a 10 year-old female after a left functional hemispherectomy. We administered a comprehensive battery of behavioral and electrophysiological tests, assessing both afferent and efferent auditory pathways. Normal peripheral hearing was established. A normal masking level difference threshold and gap detection threshol...
