UNLABELLED This study aimed at describing and analyzing tympanometric results obtained with 226 Hz and 1000 Hz probe tones; checking for correlations between tympanometry, otoacoustic emissions and otoscopic examination; describing abnormal results found in the evaluation procedures. METHODS Double-blind and prospective study. Our sample included 70 babies, between 7 days and one month and 13...

OBJECTIVE The objective of this study was to evaluate the accuracy and cost effectiveness of three different methods of hearing screening in newborns. DESIGN A prospective, randomized cohort design was used. One hundred and five newborns were tested in this preliminary study. SETTING The study was conducted in a tertiary care hospital setting in both the well baby and special care nurseries...

introduction: after presbycusis, noise-induced hearing loss is the second most common cause of acquired hearing loss. numerous studies have shown that high-intensity noise exposure increases free radical species; therefore, use of antioxidants to detoxify the free radicals can prevent cellular damage in the cochlea. we studied the potential hearing protective effect of different doses of ascorb...

Diabetes mellitus (DM) is one of the most modern chronic metabolic diseases in the world. Moreover, DM is one of the major causes of modern neurological diseases. In the present study, the therapeutic actions of Korean red ginseng were evaluated in type 1 and type 2 diabetic mouse models using auditory electrophysiological measurement. The comprehensive results from auditory brainstem response ...

in this study, generation of the transient evoked ooacoustic emissions in human ear has been simulated using a new electroacoustic model. the method of state variables was adopted to calculate the auditory model, and numerical integration methods have been used to solve differential equations in matlab. simulation results have been compared with the real data. in this study, latency curves, fre...

BACKGROUND The aim of this study was to evaluate the repeatability and variability of TEOAE characteristics in hearing screening tests performed under practical conditions on normal subjects. MATERIAL/METHODS A group of 11 young, normal-hearing subjects aged 19-24 years was tested. They were examined otologically and audiologically prior to the tests and no ear pathologies were found.
