Students and teachers used a variety of listening equipment in classroom settings and testing booths. Volume increasing headphones assisted some students in discriminating sound. Visual meters and gauges were intended to show pitch, volume and tone. Students had occasional audiological exams where they would indicate when tones were heard and try to listen, or guess words spoken by the audiologist.
This student uses an earphone to listen for tones during an audiological test at the Virginia State School for the Deaf at Hampton. Students were instructed to raise their index finger if they heard a sound.
