introduction: hearing loss after surgery is reported rarely. its prevalence rate is different and reported to be between 3-92%. hearing loss is often subclinical and not diagnosed without audiometry. the aim of this study was to determine rate of hearing changes after spinal anesthesia in patients undergoing surgery with spinal anesthesia. methods: in this descriptive study, forty male patients...

OBJECTIVE To compare pure-tone audiometry and auditory steady state response (ASSR) to measure hearing loss based on the severity of hearing loss in frequencies. STUDY DESIGN AND SETTING A total of 105 subjects (168 ears, 64 male and 41 female) were enrolled in this study. We determined hearing level by measurement of pure-tone audiometry and ASSR on the same day for each subject. RESULTS P...

background noise most frequently affects hearing system, as it may typically cause a bilateral, progressive sensorineural hearing loss at high frequencies. objectives this study was designed to compare three different methods to evaluate noise-induced hearing loss (conventional audiometry, high-frequency audiometry, and distortion product otoacoustic emission). material and methods this was a c...

OBJECTIVE This study examined the statistical properties of normal air-conduction thresholds obtained with automated and manual audiometry to test the hypothesis that thresholds are normally distributed and to examine the distributions for evidence of bias in manual testing. DESIGN Four databases were mined for normal thresholds. One contained audiograms obtained with an automated method. The...

OBJECTIVE To validate the air- and bone-conduction AMTAS automated audiometry system. DESIGN Prospective study. Test-retest reliability was determined by assessing adults with AMTAS air- and bone-conduction audiometry. Accuracy was determined by comparing AMTAS and manual audiometry conducted on adults. AMTAS testing was conducted in a quiet room and manual audiometry in a sound booth. STUD...
