Overview

Semi-Anechoic Chamber for Practical Acoustic Measurements with Real Equipment

This photo shows a modular semi-anechoic chamber featuring high-performance absorption wedges on the walls and ceiling, with a reflective floor surface for real equipment installation.
This configuration provides a practical acoustic measurement environment while minimizing the influence of sound reflections.

The chamber is equipped with wide-opening soundproof doors, allowing smooth transport and installation of test equipment.
Lighting, ventilation, and power penetrations are also integrated, making it suitable for a wide range of acoustic testing applications from R&D to production-level inspection.

Measurement target Precision equipment, automotive components, electronic components, nanotechnology related products, environmental protection products, etc.
Measurement purpose Sound power level, sound intensity measurement, abnormal noise detection, product performance acoustic measurement, etc.
Measuring equipment Standard and precision sound level meters, FFT analyzers, vibration meters, various acoustic evaluation equipment, etc.

Reference Dimensions

 

Ensure first-class sound insulation effect.

Our soundproof chamber has unparalleled sound insulation performance. Depending on the installation environment, the background noise level inside the anechoic chamber can approach 0 dB. Installing our anechoic chamber can create an advanced acoustic measurement space.

The announced sound insulation performance

We guarantee the sound insulation performance. We use a noise signal generator, speakers, and standard or precision sound level meters to measure (transmission loss test) according to JISA1417:2000 standard, and submit the test results in the form of a “measurement result report”.
