Auditory brainstem response (ABR) techniques, an electrophysiological far-®eld recording method widely used in clinical evaluation of human hearing, were adapted for ®shes to overcome the major limitations of traditional behavioral and electrophysiological methods (e.g., invasive surgery, lengthy training of ®shes, etc.) used for ®sh hearing research. Responses to clicks and tone bursts of di€e...

PURPOSE This study compared the speed, false-alarm rate, and participant preference of different response methods (raising a hand, pushing a response button, and giving an oral response) for measuring pure-tone thresholds. METHOD Thirty female university students with normal hearing participated. Response method order was randomly assigned to 6 different groups. Air-conduction thresholds were...

OBJECTIVES To validate a novel speech audiometry method using customized self-voice recorded word lists with automated scoring. PATIENTS AND METHODS The self-voice effect was investigated by comparing results with prerecorded or self-recorded CVC (consonant-vowel-consonant) word lists. Then customized lists of 3-phoneme words were drawn up using the OTOSPEECH software package, and their score...

Introduction The paramount goal for subjects with sensory-neural hearing loss is to make as precise a distinction as possible among the different sites in the sensory system where a casual lesion may lie. The usual tests of conventional audiometry· viz., pure tone sensitivity measures; tests of recruitment and abnormal tone decay; Bekesy audiometry; speech audiometry; stapedius reflex measureme...

noise is a type of energy when exceeds t.l.v., it can cause hearing loss, especially in working environments. as factory workers are at high risk of noise, the present study evaluated the bistoon tile factory workers hearing losses. in this analytical cross-sectional study, workers’ noise leq were calculated according to i.s.o. standards and their audiometry results were derived from their heal...
