background and aim: auditory p300 is an event-related potential. cognitive factors like attention are involved in the generation of p300. it seems that normative variation of p300 is necessary for clinical purposes. thus, the current study was designed to establish preliminary normative variation of p300 amplitude and latency at fz and cz sites in adults. methods: this cross-sectional study was...

conclusions the assr can accurately predict the degree and configuration of hearing loss and discriminate the normal hearing from mild or moderate hearing loss and mild from moderate hearing loss, except for 500 hz. the air-conducted assr could not define the type of hearing loss. results the assr accurately estimates the behavioral thresholds as well as flat and sloping configurations. there w...

background and aim: digits are suitable materials for hearing assessment of wide range of patients including children and adults with various language abilities. single monosyllabic 1-10 digits in triplet formant have been used for measuring speech recognition threshold in signal-to-noise ratio. the purpose of this study was to determine signal-to-noise ratio (snr) needed for 50 percent correct...
