    G.R.A.S. 45BB-7 Head & Torso for Test of Binaural Hearing Aid, 2-Ch LEMO

    The 45BB-7 KEMAR Head and Torso for test of binaural HA, 2-Ch LEMO is an acoustic research tool with built-in ear simulators that simulates the changes that occur to soundwaves as they pass a human head and torso. KEMAR fitted with pinna simulator, ear canal extension, and IEC 60318-4 Ear Simulator resembles the acoustic impedance of the human ear. This KEMAR configuration is suitable for hearing aids using RF communication by using non-metal (POM) ear canal extensions and ear holder plates.Its corresponding CCP equivalent is 45BB-8.
