Hearing testing probe apparatus with digital interface

摘要

Certain embodiments provide a hearing testing probe apparatus. The hearing testing probe apparatus includes a probe tube detachably coupled at a first end to a probe body and extending through a center hole in an eartip to align proximate a face of the eartip at a second end. The probe tube includes a plurality of stimulus lumens for receiving and carrying stimulus from the first end of the probe tube for output at the second end of the probe tube. The probe tube includes one or more microphone lumens for receiving and carrying one or more measured responses from the second end of the probe tube to one or more microphones at the first end of the probe tube.
