Creating a sound field for manipulating interaural level differences separately or independently of the interaural time differences and vice versa

Using two or more sources whose source strengths and relative phases can be controlled independently, a sound field can be generated in which the interaural pressure level differences (ILDs) and the interaural time differences (ITDs) can be controlled separately. Thus, for a fixed ILD, a range of ITDs, or vice versa, can be presented to the listener. Thus it appears possible to perform some localization experiments that had previously been confined to lateralization methods using earphones. Some calculated results for interaural time differences and interaural level differences, using two sources, will be presented.
