Reference Level Acoustic Test Fixtures

KEMAR head and torso simulators are multi-configurable and ideal for testing in laboratories and R&D where accuracy and precision in realistic simulation of head and torso-related diffraction are required. They can be used to generate 3-D simulation models of HRTF.
