The present study evaluates some characteristics of the ASSR related to the use of multiple, simultaneous, band-limited chirp-stimuli. In a diagnostic study four one-octave-band chirp-stimuli (500, 1,000, 2,000 and 4,000 Hz) were used to measure the ASSR-threshold in 10 normal-hearing adults. The four stimuli were presented simultaneously to both ears (eight stimuli) with rates at about 90/s. The ASSRs were detected automatically (error rate 5%), and the thresholds evaluated with a resolution of 5 dB. The ASSR thresholds were compared to the audiometric thresholds for all 20 ears and the deviations evaluated by the group means and standard deviations. These data compare favorably well with similar data reported by others. In a screening study a low-frequency chirp, (Lo: 180 – 1,500 Hz) and a high-frequency chirp (Hi: 1,500 – 8,000 Hz), was used to record the ASSR in 72 newborns. The two stimuli were presented both sequentially and simultaneously using a rate at about 90/s and a level of 35 dBnHL. The ASSRs were detected automatically (error rate 0.1%), and evaluated by the detection time. The results from both studies demonstrate that simultaneous application of multiple, frequency-specific stimuli can effectively be applied without sacrificing response detection accuracy. However, in the screening study stimulus interactions were observed.
