The binaural fetoscope comes with headgear for one of two reasons, or
both, I have been told by various old-timers.
The first is that it makes it easier to hear the FHT because it adds
bone conduction to air conduction, a fact which I have never been overly
impressed with, and i think the professor who rapped you over the
knuckles was wrong. I can hear quite well with the bess of a good
stethoscope. It's a sound that you have to train your ears to pick up.
The second is that a solo practitioner working without an assistant can
listen to FHT's during second stage labor without contaminating his
gloved hands.
