GRAS 45BB KEMAR Head and Torso Simulator

 

This versatile model is widely used for general acoustic testing, including hearing aid testing, headphone testing, and telecommunication device testing. It features customizable ear simulators and microphones, enabling accurate binaural audio and sound quality assessments for a wide range of applications. 

GRAS 45BC KEMAR Head and Torso with Mouth Simulator

 

Ideal for testing scenarios that require both speaking and listening simulations, this model includes a mouth simulator to replicate human speech. It is perfect for assessing the voice quality of communication devices such as telecommunication systems, headsets, and in-ear monitors. The integrated mouth simulator provides calibrated sound to simulate real-life voice intelligibility tests. 

 

 

GRAS 45BC-10 KEMAR with Mouth Simulator and Anthropometric Pinnae for Headset Test

 

This model comes with anthropometric pinnae, which more closely replicate the geometry and acoustic properties of human ears. It provides more precise simulations of human hearing, making it ideal for high-end audio research, binaural recording, and headphone testing. The GRAS 45BM ensures accurate testing for in-ear devices and binaural sound localization. 

 

GRAS 45BB-12 KEMAR

 

This is an advanced version of the KEMAR head and torso simulator, offering enhanced precision for specialized acoustic research and quality assurance of acoustic devices. It is used in 3D sound research and psychoacoustic evaluations, providing accurate HRTF measurements and binaural audio capture. 

GRAS 45BB-12 KEMAR with Anthropometric Pinnae

 

This model includes anthropometric pinnae for a more realistic simulation of human auditory perception. It is used in binaural recording, headphone testing, and high-fidelity audio research, offering precise measurements for sound localization and ear canal acoustics. This model is a preferred choice for advanced binaural sound research and audio product development.
