G.R.A.S. 45BB KEMAR Head & Torso, Non-configured

Connection: 0 V/CCP or 200 V/LEMO
Channel(s): 2
ANSI: S3.36, S3.25
IEC: 60318-7

Introduction

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. It is based on worldwide average human male and female head and torso dimensions. It meets the requirements of ANSI S3.36/ASA58-2012 and IEC 60318-7:2011. Visit KEMAR.us to read the full story.

Typical applications and use

The KEMAR head and torso simulator is used in various industries around the world.

The non-configured KEMAR head & torso simulator is primarily intended for customers having purchased the former KEMAR head & torso version (delivered before 2013) and wish to re-use configuration parts from this.

The non-configured KEMAR is delivered without application specific items which are, however, available as accessories and included as standard with the application specific versions of G.R.A.S. 45BB KEMAR Head and Torso, CCP and G.R.A.S. 45BB KEMAR Head and Torso, LEMO as well as with G.R.A.S. 45BC KEMAR Head and Torso with mouth simulator, CCP and G.R.A.S. 45BC KEMAR Head and Torso with mouth simulator, LEMO.

Compatibility

The G.R.A.S. 45BB KEMAR Head and Torso simulator has the same dimensions and acoustical properties as the original KEMAR from 1972, but has been developed further by G.R.A.S. to meet the industry’s demand for realistic measurements. It provides acoustic diffraction similar to that encountered around the median human head and torso, both in the proximity and in the far field.

The 45BB KEMAR head & torso is 100% backwards compatible with the former G.R.A.S. KEMAR Head & Torso Simulator with and without mouth (delivered before 2013).
