Introduction

The RA0237 kit includes two straight ear canal extensions designed for compatibility with the GRAS KEMAR (45BB and 45BC) and the GRAS 43AG test fixture. These extensions are intended for use with 711-style ear simulators, such as the GRAS RA0045. The RA0237 kit is compatible with all GRAS pinnae, except for the Anthropometric Pinnae and Sound Quality/VA-style pinnae.

Below is an example of a 711-style ear simulator mounted on a GRAS KEMAR or 43AG using the RA0237 kit.
