STRUCTURAL ACOUSTIC INSULATION THE IMPORTANCE OF ACOUSTIC INSULATION “Noise, dened as sound with a negative eect on one’s physical and psychic well-being, represents one of the most common factors that are harmful to the environment in which man lives and works.” The quality of acoustic insulation is one of the most important factors aecting the liveability of a house. For this reason good acoustic insulation is extremely important. EVALUATION OF ACOUSTIC COMFORT The tollerance level or maximum threshold which does not cause discomfort to the user in relation to the type of ambiance and the activity...

NOISE PROPOGATION Sound is transmitted through the air as waves of pressure. In order to propagate in the environment it needs an elastic means (gas, liquid or solid). In the specic case of noise propogation inside buildings, the propogation means are the structural components of the building such as walls and ceilings. Sound transmission takes place according to two distinct propagation mechanisms: • Air-borne; free propagation through air without encountering obstacles. • Structural; propagation through solid structures via elastic vibrations. If we consider the propagation of sound between...

ALADIN STRIPE ALADIN STRIPE EPDM soundproofing strip Suitable for common linear loads in wooden structures. We suggest specific computing to find the most suitable profile based on load transmitted from floor to wall. Absorbs up to 4 dB, according to 0 NORM EN ISO 140-7 Footstep noise reduction certified by Holzforschung Austria Specific mixture for guaranteeing performance in different environmental conditions Reduced application thickness (2 - 3 mm) Available in 2 different widths CODE VERSION LENGTH [m] WIDTH [mm] THICKNESS [mm] pcs/O

ALADIN STRIPE The EPDM strip is available indifferent sizes. It covers greater linear loads present in wooden structures and an application thickness between 2 and 3 mm can be obtained. Its installation is easy and quickbecause the product can be installed with common woodworking tools. Specific weight Hardness VERSION Soft Extra Soft Extruded EPDM Tear strength Elongation at break point Compression deformation Installation temperature APPLICATIONS AND APPLICATION TIPS • Suitable for installation between wood and wood to separate the material so as to absorb the irritating noise of footsteps....

ALADIN STRIPE AIM OF THE ACOUSTIC TEST Rothoblaas in collaboration with the Holzforschung Austria company has designed several tests to improve the soundproong qualities of the ALADIN STRIPE acoustic strip. DESCRIPTION OF THE ACOUSTIC TEST The acoustic tests were carried out on a two-storey wooden house. The house being tested had the following dimensions: 5.12 x 7.52 m. ACOUSTIC TESTING PROCEDURES The upper storey was the emitting area for all the tests, whereas the lower storey was the receiving area. The measurements were made with 3 dierent load conditions which made it possible to detect...

ALADIN STRIPE RESULTS OF THE ACOUSTIC TESTS IMPROVED EFFICIENCY Despite the important soundproong power of the oor - ceiling - false ceiling construction elements, the new composition mixtures have made it possible to greatly improve the soundproong power of the ALADIN STRIPE acoustic strip. The tests performed in collaboration with the Holzforschung Austria company demonstrated a large increase in quality with the use of ALADIN STRIPE acoustic strips. EXPERIMENTAL TEST DATA TYPE OF SOUNDPROOFING STRIP ADDITIONAL LOAD Extra soft Extra soft Extra soft * Measurements made without the use of brackets...
