Acoustic reflex patterns elicited by pulsed auditory signals were investigated in 27 normal-hearing and 27 sensorineural hearing-impaired children. An electroacoustic impedance bridge (Madsen ZO-70) was used in the measurement of the reflex. The reflex was recorded and a comparative analysis made between the patterns observed for the two groups.
A difference in the reflex response between the two groups has been identified and proven to be statistically significant. The results suggest the use of a pulsed stimulus to provide more objectivity in the identification of sensorineural hearing impairment in the unresponsive child.
