The ALGO® 3i Newborn Hearing Screener is a portable, noninvasive device for screening the hearing of infants between the ages of 34 weeks corrected gestational age and six months. The screener uses Natus’ AABR® technology. Babies should be well enough for hospital discharge, and should be asleep or in a quiet state at the time of screening. The ALGO 3i screener is simple to operate and does not require special technical skills or interpretation of results. Basic training with the equipment is sufficient to learn how to screen infants correctly. A typical screening can be completed in 15 minutes or less in any clinical environment (i.e. well-baby nursery, NICU, mother’s bedside, audiology suite, outpatient clinic, or doctor’s office).
An electroacoustic instrument designed to evaluate the activity of the auditory pathway of the brain in response to an acoustic signal [auditory brainstem response (ABR)] it provides at the ear (e.g., clicks delivered through an earphone), without need of patient cooperation. The signal, detected via the device's scalp electrodes and possibly a reference electrode on the ear lobe, is measured using computer averaging and signal processing techniques. This device is typically used to assess the function of the auditory pathways and to differentiate coma due to metabolic factors from structural damage.
