Full and Hemi-anechoic Chambers

VG Engineering Inc. full and hemi-anechoic chambers are designed to meet internationally recognized specifications.

Features of our anechoic chambers include:

  • Acoustic wedges provide low frequency cut-off in accordance with specification requirements and are available in a number of finishes and colors to suit architectural requirements.
  • Modularized anechoic chambers can be assembled and dismantled for easy relocation without change to acoustic performance.
  • Independently tested and certified acoustic components.
  • Full anechoic chambers feature suspended cable or grid based non-reflective floor systems to simulate “free field” conditions.
  • VGE sound-insulated wall and ceiling panels provide high Transmission Loss ratings.
  • Vibration isolated floor systems
  • Ventilation and power systems where required
  • Commissioning services provided as required

Uses include:

  • Instrumentation Testing
  • Consumer Product Development
  • R & D Development
  • Vehicle NVH Testing Ancillary Equipment Testing
  • Clinical Audiological Testing

Acoustic Wedges

VG Engineering provide custom made large foam and fiberglass wedges are used in a wide variety of acoustic applications where maximum absorption is required or low frequency control is desired. Typical applications include:

Anechoic and Semi-Anechoic chambers for:

  • Testing vehicles
  • Electro-mechanical equipment
  • Internal combustion engines
  • Scientific equipment and machinery
  • Any application that requires a room with no sound reflection
