Lillian Biehner, right, supervisor of Pierce County school nurses, conducts a test on the students' hearing at Ruston School on May 6, 1941. An audiometer, in the suitcase on the right, contains a record player connected to 20 sets of earphones. Children write down the numbers they hear over the recording. Students in the left row are Jimmy Tallman, Marjorie Dimmen and Ned Face.
