OBJECTIVE Auditory processing difficulties have been reported in schizophrenia. This study explores peripheral auditory function in patients with schizophrenia in whom certain early disturbances of auditory message filtering have been found and may be associated with certain abnormalities which are particularly localised in the left temporal lobe. METHODS Otoacoustic emissions, including clic...

OBJECTIVE The aim of this study is to investigate otoacoustic emissions (OAEs) in young children with autism compared with those in an age-matched control group. MATERIALS AND METHODS Thirty-eight children with autism aged 3-6 years and 27 typically developing (normally developing) control subjects participated in this study. All the participants had normal hearing and middle-ear function. Au...

Click-evoked otoacoustic emissions (CEOAEs) are clinically used as an objective way to infer whether cochlear functions normal. However, because the sound pressure level of CEOAEs is typically much lower than background noise, it usually takes hundreds, if not thousands repetitions estimate signal with sufficient accuracy. In this paper, we propose improve signal-to-noise ratio (SNR) CEOAE sign...

UNLABELLED Exposure to loud noise is one of the main causes of tinnitus. AIM To analyze the incidence of tinnitus in mp3 player users and non-users. MATERIAL AND METHOD One hundred subjects aged from 15 to 30 years were enrolled, 54 of them were regular mp3 player users and 46 were not. Patients with continuous tinnitus for at least 6 months completed the Tinnitus Handicap Inventory (THI) a...

UNLABELLED Characteristics of how external and middle ear resonance frequency can impact the capture of otoacoustic emissions. AIM to study the impact of external and middle ear resonance frequency in otoacoustic emissions. STUDY DESIGN Prospective, clinical, series study. MATERIALS AND METHODS Microphone-probe measurements were made in the external ear, together with multifrequency timpa...
