GRAS AL0030 Production Line Acoustic Test Chambers

Introduction

The GRAS AL0030-x Production Line Acoustic Test Chambers are an anechoic test chambers for acoustic production line testing of mobile devices, for example cell phones, tablets, bluetooth speaker systems and similarly sized portable acoustic devices. It provides a flexible platform that can be configured to suit specific requirements.

Design

It is built from medium density fiber board lined with acoustic damping material. A large opening at the back of the chamber allows easy access to the chamber for configuring the test setup. The chamber has shock and vibration absorbing feet that prevent vibration from the outside from influencing the measurements.

It has a drawer with multi-adjustable holders for easy and safe mounting and removal of the device under test (DUT). It can hold small and medium sized portable devices up to (WxDxH) 300 x 200 x 228 mm (12″ x 8″ x 9″).

The test chamber has four fixing points for microphones and sound source, two at the top and two at the bottom panel. Holders for a total of four microphones and/or sound sources can be mounted at these fixing points. Additionally, a microphone can be attached to the drawer.

A connector panel that can be configured with 8 or 10 (depending on drawer size) user-specified connectors provides interface to external instruments. You find more information in the "Brochure" , also available in the "Resources".
