抄録
40Hz ERP reported by Galambos et al, were recorded on 14 adults and 7 infants with normal hearing, on 2 patients with conductive hearing loss and 4 patients with sensori-neural hearing loss.<br>The results were as follows. 1. The wave form of 40Hz ERP was similar to 40Hz sine waves and the prominent peak in the power spectrum was observed at 40Hz. 2. The amplitude of 40Hz ERP increased as the stimulus intensity was increased. 3. 40Hz ERP was obtained for the tone bursts of 500Hz, 1000Hz, 2000Hz and 4000Hz. However, the amplitude of the response decreased for the stimuli in the high frequency range. 4. The response thresholds were 0-30dB in adults and 5-40dB in infants. 5. The large response of 5μV was recorded on 2 out of 27 cases. This seems to be a myogenic response. 6. The response threshold curves both in patients with conductive hearing loss and sensorineural hearing loss, were parallel to their audiograms.
