GRAS AL0030 Production Line Acoustic Test Chamber
Self Insertion Loss: >25 dB
CCP Microphone set
Technology
Introduction
The GRAS 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.
Design
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 (DUT). It can hold small and medium sized portable devices up to 300 x 200 mm (12″ x 8″).
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 (see Ordering Info for details).
A Flexible and Configurable Test Platform
AL0030 provides a flexible test platform that can be configured to suit specific needs.
- The basic configuration includes user selectable accessories for immediate acoustic testing.
- Additionally, the test chamber can be fittet with a sound source and an artifial ear.
- If you have needs that are not covered by these options, we can customize it to suit your specific needs. Contact (your local) GRAS (representative) to initiate the process.
