Multichannel infant reflex audiometry (MIRA) a new method for evaluating hearing in infants (preliminary results)

Multichannel infant reflex audiometry, applicable up to about 1 year of age, is based on the simultaneous registration of sucking and breathing activities and of eye movements together with marks which indicate the side, beginning, and end of the stimulus. Sucking and breathing are reduced or altered by suprathreshold stimuli. The threshold of responses is 20-40 dB lower than that obtained with behavioral tests and comparable in most cases with BERA thresholds.
