A§E contains 2 localization tests: (1) ILD localization and (2) azimuth localization. The azimuth localization is a typical localization test with 5 or 7 loudspeakers. This test requires the SoundC hardware (contact Otoconsult for more information). The ILD localization test only requires 2 loudspeakers. It assesses the localization acuity based on high frequency interaural level differences and is mainly useful to evaluate cochlear implant recipients.
