Technology
Design
The RA0157 pistonphone calibration adapter enables the calibration of 711-style ear simulators, such as the GRAS RA0045, when mounted in test fixtures like KEMAR, 45CB, 43AG, or 45CA. It is designed for use with ear canal extensions such as the GRAS RA0237, RA0249, GR1069, or GR1482.
This adapter is not compatible with GRAS test fixtures fitted with Anthropometric Pinnae (e.g., KB5000 or KB5010) or configurations that do not include a 711-style ear simulator. It is exclusively designed for use with GRAS 42AA or 42AP pistonphones.
Below are images demonstrating how to mount the RA0157 calibration adapter on a GRAS 42AA or 42AP pistonphone for calibrating 711-style ear simulators in GRAS test fixtures such as KEMAR, 45CB, 45CA, and 43AG.
