What is the doctor who gives hearing test called?

An Audiologist is a doctor (though some are able to practice with MS in Audiology because they were grandfathered-in--so, those audiologists are not doctors) who administers hearing tests. Nurses are able to administer newborn hearing screenings, which don't require the nurse to do any diagnostic or interpretative functions.
