... in 1999 in Russia. They have high rates of additional sound insulation (9...18 dB) depending from thickness of 43...120 mm. This system was patented and still is widely in use. In addition, the system provides the necessary durability and ease of installation. Over 20 years, the system has undergone several upgrades. The article describes the physical principle of the ZIPS-system, the calculation data and laboratory acoustic measurements, latest modification of the system with adjustable mounts.
