KEMAR Meaning and
Definition
-
KEMAR, also known as the Knowles Electronics Manikin for Acoustic Research, is a head and torso simulator used in acoustics research and testing. Developed by Dr. S. A. Knowles in the 1970s, KEMAR is designed to replicate the acoustical properties of the human head and upper torso. It is commonly used in audio engineering, audiology, and telecommunications to analyze and assess the sound quality, speech intelligibility, and localization of sound sources.
KEMAR consists of an anatomically accurate manikin head with built-in ear simulators that resemble the average human ear. The ear simulators feature baffles and artificial ear canals that mimic the resonant characteristics of real human ears. These features take into account the head-related transfer functions (HRTFs) – the filtering effects of the head and torso on sound – which significantly influence the perception of sound direction and spatial cues.
Researchers utilize KEMAR by attaching it to various audio devices or systems, such as headphones or loudspeakers, to capture and measure the acoustic responses. By replicating the human listening experience, KEMAR allows for precise acoustical measurements and evaluations, enabling researchers to optimize sound systems, assess the impact of different factors on sound perception, and develop technologies that enhance sound quality and localization.
Overall, KEMAR serves as a vital tool in acoustics research, providing a standardized and reliable means to investigate and improve auditory perception and communication systems.
