45BB KEMAR Head & Torso, Non-configured
The 45BB KEMAR head and torso is a configurable acoustic research tool that simulates the changes that occur to sound waves as they pass a human head and torso. Its equivalent with mouth simulator is GRAS 45BC KEMAR Head & Torso, non-configured
The KEMAR head and torso simulator was introduced by Knowles in 1972 and quickly became the industry standard for hearing-aid manufacturers and research audiologists (visit KEMAR.us to read the full story). The GRAS KEMAR has the same dimensions and acoustical properties as the original KEMAR from 1972 and is 100% backward compatible.
When fitted with pinna simulator, ear canal extension, and IEC 60318-4 Ear Simulator, KEMAR closely mimics the acoustic properties of the human ear.
