Music is usually recorded using traditional microphone techniques. With technology continually advancing, binaural recording has become more popular, that is, a recording where two microphones are used to create a three-dimensional stereo image. Commercially available binaural heads are prohibitively expensive and not practical for use in typical educational environments or for casual use in a home studio. This experiment consisted of gathering recorded stimuli with a homemade binaural head and the Neumann KU 100. The recordings were played back for 34 subjects instructed to rate the level of externalization for each example. The study investigates whether a homemade binaural head made for under $500 can externalize sound as well as a commercially available binaural head the Neumann KU 100.
