Lateralization means that the test tone is heard in the ear being checked and is not related to not being able to hear the test tone or hearing it in the non-test ear.

Lateralization refers to the phenomenon where a test tone is heard in the ear being checked. It is not related to not being able to hear the test tone or hearing it in the non-test ear. For example, in sound localization, the brain calculates the interaural time difference and the interaural intensity difference to determine the location of a sound source.
