Low frequencies have longer wavelengths, allowing them to diffract or bend around obstacles such as the listener's head more easily than high frequencies. This results in smaller interaural intensity differences for low frequencies compared to high frequencies, which are less able to bend around the head and thus create larger intensity differences between the ears.
