An evoked-potential audiogram was measured for an Indo-Pacific humpback dolphin (Sousa chinensis) living in the dolphinarium of Nanning Zoo, China. Rhythmic 20 ms pip trains composed of cosine-enveloped 0.25 ms tone pips at a pip rate of 1 kHz were presented as sound stimuli. The dolphin was trained to remain still at the water surface and to wear soft latex suction-cup EEG electrodes used to m...

BACKGROUND The prevalence of sudden sensorineural hearing loss in children (CSSNHL) is consistently increasing. However, the pathology and prognosis of CSSNHL are still poorly understood. This retrospective study evaluated clinical characteristics and possible associated factors of CSSNHL. METHODS One hundred and thirty-six CSSNHL patients treated in Department of Otolaryngology-Head and Neck...

Most hearing aid fittings today are almost solely based on the patient's audiogram. Although the loss of gain in the cochlea is important , for a more optimal fitting, more individual parameters of the patient's cochlear loss together with the patient's cognitive abilities to process the auditory signal are required (Stenfelt & Rönnberg, 2009; Edwards, 2007). Moreover, the evaluation of the fit...

BACKGROUND Healthy hearing depends on sensitive ears and adequate brain processing. Essential aspects of both hearing and cognition decline with advancing age, but it is largely unknown how one influences the other. The current standard measure of hearing, the pure-tone audiogram is not very cognitively demanding and does not predict well the most important yet challenging use of hearing, liste...

Introduction  Sudden hearing loss is one of the otologic emergencies. The treatment of this disease is affected negatively by some prognostic factors. Objective  In this study, the effects of early treatment initiation in patients with idiopathic sudden hearing loss and of prognostic factors in early treated patients were investigated. Methods  Out of the 216 patients admitted between September...
