Pure Tone Audiometry
... When a signal is presented to the test ear, the signal may also travel through the head and reach the cochlea on the other side. However the intensity of the signal from the test to the non-test ear can be reduced by the mass of the head. This signal reduction is called interaural attenuation. ...
