When the sound source is close to the head, the head itself acts as a barrier, causing a significant difference in the intensity of the sound reaching each ear. This effect is less pronounced when the sound source is far from the head, as the sound waves have more space to spread out and reach both ears more evenly. Magnetic fields do not directly affect sound intensity differences between the ears.
