The 47 MDS is a hybrid acoustic hanger made with the latest technology and with high quality raw materials. It is designed for suspended ceilings with ceiling channels such as TC47, F530, MAESTRA 4717 or similar.
The HYBRID system is the combination of a polymer (rubber) and a steel spring.
The combination of these two elements allow us to label it in its category as the best acoustic insulator in the world. It is reducing vibration throughout the range of excitatory frequencies.
There are 4 different models depending on load range and colour: Grey, Green, Blue and Red
✓ 4715 G/MDS (Load range from 3 up to 15 kg)
✓ 4725 V/MDS (Load range from 15 up to 30 kg)
✓ 4750 A/MDS (Load range from 30 up to 50 kg)
✓ 4775 R/MDS (Load range from 45 up to 75 kg)

Test Report Nº: B2021-LACUS-IN-160 A
Purpose: Airborne Soundproofing Test AND Impact Noise Insulation Test
Standards: UNE-EN ISO 10140-1:2016, 10140-2:2011 and 10140-3:2011+A1:2015
Laboratory: TECNALIA (Vitoria, SPAIN)
Date: 25 November 2021
Sample: CHOVA+SENOR SUSPENDED ACOUSTIC CEILING – EI120
Standardised Base Floor: Reinforced concrete slab
Standardised Base Thickness and Weight: 15 cm and 375 kg/m²
Total Acoustic Ceiling Thickness: 30 cm
Sample Description: Suspended acoustic ceiling system comprising: SE-60M/DS dampers (SENOR) + SE-BEC-10×80 acoustic strip (SENOR) + TC-60 profiles (KNAUF) + SE-MONT-BICAPA-40 decoupling strip (SENOR) + 4 cm CHOVANAPA sound-absorbing material (CHOVA) + 25 mm Fireproof Plasterboard (KNAUF) + 4 mm VISCOLAM 65 acoustic membrane (CHOVA) + 25 mm Fireproof Plasterboard (KNAUF).
Note: The soundproofing results obtained in this test are also valid for the 47MDS product, as both products share the same properties.
Result: An improvement of 22 dB in airborne sound compared to the base floor, which has a rating of 57 dB, resulting in a total soundproofing of 78 dB.
Result: Reduction of 34 dB in impact noise compared to the base floor, which has a rating of 77 dB, achieving a total soundproofing of 42 dB.
