Hemi-Anechoic Chamber and Multi-Axis Shaker Table

The ACE Hemi-Anechoic Chamber and Multi-Axis Shaker Table (MAST) is a unique and highly optimal space for product development and prototype validation of all kinds. It offers repeatable, high-frequency, six-degrees-of-freedom simulation of the vibrational environment of products and components. Being a hemi-anechoic chamber, this space is specially designed so that the walls absorb and break up sound waves, enabling microphones from our acoustic array to pick up the squeaking and rattling of test products.

The MAST is ideal for testing:

  • Durability
  • Noise, vibration, and harshness (NVH)
  • Squeak and rattle


Any sector that develops, tests, and brings new products or components to market will find immense value in the MAST. This space is also commonly used for Film and Media production. Sectors include:

  • Automotive
  • Defence
  • Film and Media

Testing Examples:

  • Air-turbulence and uneven-surface landing simulations
  • Automotive components lifecycle/squeak and rattle
  • Construction/architectural design and materials (earthquake simulations)
  • Heating, ventilation and air conditioning (HVAC) subsystems lifecycle/squeak and rattle
  • UAVs

Key Features

  • 150 Hz cut-off frequency with exceptionally low background noise
  • Six-degrees-of-freedom (three translational; three rotational) inverted hexapod hydraulic shaker table

Acoustic Array in Hemi-Anechoic Chamber

Our Acoustic Array is ideal for Noise Source Identification. Featuring 108 microphones on 18 arms, it forms a half circle which utilizes the sound reflection off the ground plane of the chamber to effectively act as a full-circle array. Our array is portable and is most often utilized in the Hemi-Anechoic Chamber and the Climatic Aerodynamic Wind Tunnel. 

Garage Bays

Three high-secure garage bays are available for use throughout testing. Garage bays come equipped with a hoist and tools and requires badged access for the highest level of security and privacy.
