Sonora Anechoic Box
Anechoic box is a small acoustic box which have the feature of high sound insulation( transmission loss) and sound absorption. It’s applied to measuring the noise of a product, inspecting the abnormal sound, quality control, research and development.
Utilizing our noise control technology, we developed special multi-layer panel. Over the past 9 years, we have proposed, designed and manufactured over 300 units according to a wide various using purposes and specifications. The high sound insulation performance with guarantee performance is unrivaled compared with other companies.

About Sound Insulation Performance
We can guarantee the sound insulation performance by using a noise signal generator, speaker, general noise meter or precise noise meter, measuring (transmission loss test) according to JISA1417:2000. And submit the test result as a “Measurement Result Report”.
