When sounds are conducted separately and independently to each ear via tubes or headphones, the sounds are said to be heard dichotically. In various psychoacoustic experiments, isolation of the function of each ear is desirable, such as in the testing or simulation of BINAURAL HEARING with the PRECEDENCE EFFECT, or in testing preferences for different sounds presented simultaneously to separate ears.
