[Multichannel infant reflex audiometry (MIRA)]. / Multichannel Infant Reflex Audiometry (MIRA).

A new method for evaluation of hearing threshold in babies is presented. The method does not require much time, cost or personnel and is practicable for infants up to about 12 months. It is based on synchronous electrical registration of sucking and breathing activities as well as of eye movements evoked by acoustic stimuli. Sucking and breathing are reduced by supra-threshold stimuli, preparing the baby for attentive listening. Eye movements are directed towards localizing the site of the stimulus.
