The G.R.A.S. AL0030 Production Line Acoustic Test Chamber is an anechoic test chamber 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.


It is built from medium density fibre 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. It can hold small and medium sized portable devices up to 300 x 200 mm (12 x 8 inches).

The test chamber has 4 fixing points for microphones and sound source, 2 at the top and 2 at the bottom panel. Holders for a total of 4 microphones and/or sound sources can be mounted at these fixing points. Additionally, a microphone can be attached to the drawer.

A connector panel with 4 BNC connectors, 2 USB, and 2 Mini DIN connectors provides connections to external instruments.
