Anechoic Chambers | Acoustic Chamber - APC Technology Group

Anechoic Chambers

Custom EMC Anechoic Chambers designed, built and tested to your requirements.

APC’s specialist team is here to support product designers and engineers to overcome unintentional EMC issues. Often resulting in unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment, our team offer a range of EMC testing solutions from some of the world’s leading manufacturers.

What is an Anechoic Chamber?

Anechoic Chambers are the ultimate testing ground for engineers and scientists looking for precise acoustic measurements. These specialised enclosures are a contrast between two elements. contrast to echo chambers, designed to minimise sound reflections and reverberation. This particular construction features walls, ceiling and floor lined with highly effective anechoic materials including a high sound absorption coefficient (SAC), which essentially "absorbs" sound waves, preventing them from bouncing back and interfering with measurements.

The resulting environment approximates a free-field condition, allowing sound waves to propagate outward from the source object with minimal distortion. This enables accurate sound pressure level (SPL) and other acoustic parameter assessments from any direction around the test object.

By eliminating echoes and reflections, anechoic chambers empower researchers to gain a deeper understanding of a product's acoustic performance, leading to improved design and noise reduction strategies.

Anechoic Chamber UK Suppliers

APC in partnership with ETS-Lindgren provide a wide range of Anechoic Chambers for the UK market.

Anechoic Chambers are used by a wide range of industries for testing and measuring electromagnetic compatibility, antenna testing, wireless device testing, sound testing, and other related applications.

At APC we see projects through from specification through to sign-off and handover.

Wave Guide Feed-through / Pipe Penetrations

A waveguide feed-through, also known as a pipe penetration, is a device used to allow a waveguide to pass through a shielded wall or barrier while maintaining a high level of electromagnetic interference (EMI) and radio frequency interference (RFI) shielding. Waveguides are used to transmit electromagnetic signals at high frequencies and are commonly used in microwave and radar systems.

A waveguide feed-through consists of a metallic pipe that passes through a hole in a shielded wall or barrier, with the waveguide inserted into the pipe. The metallic pipe is carefully designed to attenuate electromagnetic waves over a wide range of frequencies. This means that EMI/RFI signals that attempt to pass through the feed-through are significantly weakened before they can penetrate the shielded wall or barrier.

  • Accommodate requirements such as fire suppression systems, hydraulics and other Utilities
  • Honeycomb waveguide insert option available for high frequency or gaseous applications
  • Dielectric unions are available to maintain isolation to the ground

Wave Guide Feed-through / Pipe Penetrations

EMI/RFI shielded waveguide air vents are used to provide ventilation to shielded enclosures or rooms, while at the same time preventing electromagnetic interference (EMI) and radio frequency interference (RFI) from entering or leaving the enclosure. These air vents are typically used in electronic equipment and facilities, where EMI/RFI can cause incorrect readings or malfunctions.

The EMI/RFI shielded waveguide air vents are designed to allow airflow while maintaining a high degree of shielding effectiveness. The waveguide structure of the air vent is carefully designed to attenuate electromagnetic waves over a wide range of frequencies. This means that EMI/RFI signals that attempt to pass through the air vent are significantly weakened before they can penetrate the shielded enclosure.

  • Available in 3.175 mm (1/8 in) and 4.76 mm (3/16 in) Honeycomb Cell Geometry
  • Adaptable to a variety of mounting flanges and gasket techniques
  • Brass or steel core material with tin coating for superior RF performance and corrosion resistance
  • Minimal air flow resistance and pressure drop
  • Continuous solder-fused for superior strength and RF performance

RF Doors

APC provide ETS-Lindgren RF Shielded doors. ETS provide doors for a wide range of applications up to 100dB at 40GHz.

For more convenient use, the door may be fitted with a pneumatic opening and closing mechanism as an optional feature. This system can release the RF tight seal, enabling the door to be manually operated with less effort.

Overall, radio frequency shielded doors are an important component of many modern facilities that rely on sensitive electronic equipment or need to protect against external RF interference.

  • Easy to operate
  • Patented hinges allow final closing movement to be parallel to door frame
  • Permit normal swing when fully opening door
  • Final RF seal obtained by cam followers
  • Optional pneumatic operation
