Introduction: Sensorineural hearing loss (SNHL) is a probable complication of coronary artery bypass graft (CABG) Surgery, that may be due to embolism, perfusion failure and consumption of ototoxic drugs. Since the incidence of SNHL after CABG is different according to the various reports, the present study was designed to study hearing threshold change after CABG surgery. Method: In this cross...

original article   extended exposure to noise can cause permanent hearing damage. this study aimed to determine the incidence time of hearing loss and its effective factors in workers exposed to noise. this retrospective cohort study, was conducted on a total of 273 workers in various sectors of kerman copper by-industries co. their hearing status and the incidence of hearing loss (hearing thre...

The aim of this study was the evaluation of hearing threshold in patients with beta thalasemia major. For this purpose, 178 patients who were under regular chelation therapy with desferrioxamine (DFO) were selected and underwent ear, nose, throat examinations and audiological evaluations. Patients were between 4 to 25 years old and 54.9% were male and 45.1% were female. Three patients were excl...

BACKGROUND Previous studies have demonstrated that cortical auditory-evoked potentials (CAEPs) can be reliably elicited in response to speech stimuli in listeners wearing hearing aids. It is unclear, however, how close to the aided behavioral threshold (i.e., at what behavioral sensation level) a sound must be before a cortical response can reliably be detected. PURPOSE The purpose of this st...

OBJECTIVES (1) To determine the ototoxicity detection rate (sensitivity) for distortion-product otoacoustic emissions (DPOAEs) testing in adults who received ototoxic medications and experienced pure-tone threshold changes during the course of treatment; (2) to determine the extent to which DPOAE sensitivity to ototoxicity depends on the type of drug administered (platinum or antibiotic), magni...

This retrospective study examines the relationship between auditory steady-state evoked potential (ASSEP) thresholds determined in infancy and subsequently obtained behavioral hearing levels in children with normal hearing or varying degrees of sensorineural hearing loss. Overall, the results from 211 subjects showed that the two test techniques were highly correlated, with Pearson r values exc...

abstract   introduction: conductive hearing loss attenuates and delays sound transmission in the middle ear. it can make variety of central auditory processing disorders; that persists even after resolve of peripheral auditory system problems. one of the aspects of central auditory processing is the temporal processing, which is important for understanding speech, including temporal resolution,...

The primary goal of the current project is to better understand auditory masking by determining masking patterns for a broad variety of environmental noise types, and define the mechanisms that govern auditory signal processing in environmental noise. Behavioral threshold methods developed at SSC San Diego (Finneran, Carder, Schlundt, & Ridgway, 2005) allow thresholds to be obtained rapidly (i....
