GRAS 43BB-1 Low-noise Ear Simulator System

GRAS 43BB-1 Low-noise Ear Simulator System

Introduction

The GRAS 43BB-1 is a low-noise, high-sensitive ear simulator system for measurements of sound pressure levels close to or below the threshold of human hearing.

It is identical to the 43BB Low-noise Ear Simulator System except that it uses an angled adapter for the preamplifier, and therefore can be used in binaural setups inside a 45BB KEMAR or a 45BC.

43BB-1 is part of the  45BB-12 KEMAR with Anthropometric Pinna for Low-noise Ear- and Headphone Test 2-Ch LEMO, and 45BC-12 KEMAR with Mouth Simulator and Anthropometric Pinnae for Low-noise Headset Test, 2-Ch LEMO.
