Stereophonic Hearing Equipment Set

The Stereophonic Hearing Equipment Set allows for the investigation of directionality of sound, or determining differences in time for sound to propagate to left and right ears by generation of knocking sounds in a closed tube. The effect of linear distortions on the directionality of cavity resonance can also be investigated by dipping two ends of a tube, at the same time or in alternation, into a beaker which is either empty or half-filled with water. The set consists of a stethoscope with various tubes and a plastic beaker, all contained in a rugged plastic case with foam inlays in the shape of the apparatus, and a transparent lid.
