==== Audio Technician ====

Mid-day the next day, the audio technician came by and checked whether our daughter could hear. Avoiding a problem here was the principal motivation for lots of things that we did, so we waited with bated breath.

The service itself is provided by [https://www.pediatrix.com/our-services/pediatric-care/newborn-hearing-screen Pediatrix] and uses a [https://natus.com/sensory/algo-5/ Natus Algo 5] which uses automated [[wikipedia:Auditory brainstem response|auditory brainstem response]] to detect if the baby can hear. The short version of things is that they place a bunch of sensors on the baby's body, then a pair of headphones that deliver some sounds, and then measure the brain's response to these.

The test took about 91 seconds to report a PASS result. The alternative is a REFER result.
