SENOR – 47 MDS
Fire Resistance Test EI120 TECNALIA (Azpeitia – Guipúzcoa)
Utility Model
200201413/2
High-Performance Acoustic Ceiling with EI120 Fire Rating Airborne Noise (RA,con:77,3 dBA -DnTA > 75 dBA)
Model 47 MDS
This innovative hybrid acoustic hanger has been meticulously designed to offer an experience of tranquility and comfort in environments where intense activity can generate impact noise and disturbing vibrations. These situations are especially common in places where noise levels exceed 100 dBA during nighttime hours, such as live music venues, party rooms, theaters, cinemas, nightclubs, and wedding halls. In these spaces, daily interactions and ambient noise can cause discomfort both to clients enjoying the events and to citizens in the vicinity of the premises, highlighting the need for effective solutions for soundproofing. The model 47 MDS incorporates a patented system that includes a locking device considered the safest on the market, called **DS**. This component not only optimizes the performance of the acoustic hanger, but also significantly increases the mechanical safety of the system, preventing its potential collapse. Once this mechanism grips the metal framing, it holds it firmly without letting go, ensuring a robust and reliable integration. In fact, tests have shown that this model can be between two and three times more effective compared to traditional or similar damping systems, positioning itself as a superior choice for those looking to mitigate noise and maximize comfort in sound-filled environments. Its implementation translates into a more pleasant environment both for internal users and for those outside the establishment.

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.
