Test Report Nº: B2022-LACUS-IN-175 A
Purpose: Airborne Soundproofing Test AND Impact Noise Insulation Test
Standards: UNE-EN ISO 10140-1:2022, 10140-2:2022 and 10140-3:2022
Laboratory: TECNALIA (Vitoria, SPAIN)
Date: 19 and 20 – May – 2022
Sample: CHOVA+SENOR LIGHTWEIGHT ACOUSTIC FLOOR WITH WOODEN BATTENS
Standardised Base Floor: Reinforced concrete slab
Standardised Base Thickness and Weight: 15 cm and 375 kg/m²
Total Acoustic Floor Thickness: 14 cm
Sample Description: Lightweight acoustic floor system comprising: SE-FTD RASTREL L dampers (SENOR) + SE-BEC-15×170 acoustic strip (SENOR)
+ 40×40 mm pine battens + SE-MONT-BICAPA-40 decoupling strip (SENOR) + CHOVACUSTIC PLUS FIELTEX multilayer component (CHOVA)
+ 4 cm CHOVANAPA sound-absorbing material (CHOVA) + 16 mm MDF board + 6 mm VISCOLAM 100 acoustic membrane (CHOVA) + 16 mm MDF board.
Result: An improvement of 14 dB in airborne sound compared to the base floor, which has a rating of 58 dB, resulting in a total soundproofing of 72 dB.
Result: Reduction of 29 dB in impact noise compared to the base floor, which has a rating of 78 dB, achieving a total soundproofing of 48 dB.
