LBX ACB20 PERFECT AUDIO VALIDATION

LBX ACB20 PERFECT AUDIO VALIDATION - LabiFix RF Shield Box, front viewLBX ACB20 PERFECT AUDIO VALIDATION - LabiFix RF Shield Box, rear view

LBX ACB20 Acoustic Enclosure serves as an effective and controlled acoustic testing, featuring configuration options that can be tailored to the specific test setup. Its design allows for the integration of an acoustic gasket system along with connectivity and access, without necessitating a fixed arrangement for the device under test (DUT). This enclosure provides a flexible pathway to controlled device-level acoustic testing, enabling the assessment of acoustic products such as speakers, receivers, and microphones in a stable environment characterized by a low noise floor of 25-30 dB. In a noisy environment of 60 dB, the internal noise level is 25 dB. In a noisy environment of 80 dB, the internal noise level is less than 35 dB.

LBX6650 RF Shield Test Box is a high-attenuation enclosure engineered to isolate electronic devices from external EMI/RFI while containing wireless emissions generated inside. Heavy-duty construction, RF absorber materials, filtered interfaces, and ventilation options help maintain a stable test environment without sacrificing essential connectivity. It is suitable for repeatable laboratory measurements, high-volume manufacturing tests, OTA evaluations, and troubleshooting. Applications include smartphones, wearables, IoT hardware, wireless modules, and other electronic products where ambient RF interference can cause inconsistent or misleading test results. It helps engineers create controlled, repeatable RF testing environments for accurate measurements and troubleshooting.

About this range

LabiFix acoustic test enclosures (LBX-ACB20 and LBX-ACB30) are sound absorbing chambers for speaker, receiver and microphone validation.

High-density acoustic wedge and foam lining and vibration-isolated feedthroughs hold the internal noise floor to 25–30 dB SPL, even in 60–80 dB ambient environments.

  • 25–30 dBInternal noise floor
  • 30–45 dBAcoustic attenuation
  • < 35 dBInside at 80 dB ambient

People often search for anechoic chamber sound solutions when they need a quiet measurement space. An acoustic anechoic enclosure controls audible noise, whereas an RF anechoic chamber controls radio reflections; the two are different products and RF absorber does not provide acoustic soundproofing.

Acoustic Enclosure Performance

  • Internal noise floor 25–30 dB with 60 dB ambient noise outside.
  • Internal level below 35 dB with 80 dB ambient noise.
  • Acoustic attenuation of 30–45 dB.
  • Gasketed doors and acoustic cable feedthroughs.

Frequently Asked Questions

What is an anechoic chamber sound enclosure?
It is an acoustic test chamber lined with sound-absorbing wedges or foam so reflections and ambient noise are minimised for audio measurement.
