Project introduction

LandVac is used in a high-end bar in Xi’an. 

Thanks to the high vacuum chamber of LandVac , which effectively blocks the sound transmission, the sound insulation performance is far better than insulated glass. It has remarkable acoustic properties against high penetrative medium and low frequency noises.With its weighted sound reduction index exceeding 39 dB, LandVac makes rooms in downtown quiet like a library.
