Auditory Localization Instrument
base: l x w; 56 x 18 cm
year made: c. 1910
Students used this instrument for exercises in auditory localisation. A sound source (tuning fork) would be placed at the entrance of the single input tube. The sound would travel through the two tubes, of adjustable length, toward the two outputs. The middle unit slided to and fro in order to adjust the phase conditions.
The psychology department owns several copies of this instrument, each numbered for classroom use. The original instrument appeared in the British Journal of Psychology in 1908.
