NEW RESULTS OF LABORATORY TESTS FOR AKUSTIK+SYLOMER SOUND CLIP AND AKUSTIK+SYLOMER FLOOR MOUNTS USED ON CONCRETE SLABS

7/9/2024

INTRODUCTION

The majority of buildings use concrete structures as the base material for the construction of different works. It is a low-priced material compared to steel, with a resistance similar to or greater than that of brick, which offers the possibility of building elements of almost any shape.

For this study, a range of tests have been carried out using different solutions for floating floor and the suspended ceiling installations with different types of AMC supports.

The tests were carried out by the National Research Council (NRC) of Canada.

THE PRODUCTS TESTED ARE THE FOLLOWING:

AKUSTIK + SYLOMER SOUND CLIP

Akustik + Sylomer® Sound Clip hangers are designed for the floating suspension of soundproofed ceilings and partitions installed with Omega type profiles. This type of supports, thanks to its low profile, lose very little space.

The Sylomer® avoids the transmission of vibrations and gives optimal acoustic results. They have a robust metal structure that is overload-proof and fail-safe. The interlocking components ensure that the hanger is mechanically captive in the event of an unexpected shock or fire event

AKUSTIK + SYLOMER FLOOR MOUNTS

Akustik + Sylomer® Floor mounts are anti vibration mounts that have been designed for the installation of wooden floors which use a slat system. Its easy installation and low space requirement allows for exceptional vibration and noise isolation as part of a floating floor application.

These supports are normally installed every 0.5 meters. However this distance can be adjusted to suit the load or natural frequency requirement of the application. The natural frequency at its optimum load point reaches values below 12 Hz. These properties provide a high level of noise and vibration insulation when used in light wooden structures.

TEST RESULTS

In order to show the acoustic advantages of using the aforementioned supports in a concrete structure, impact noise and airborne noise tests have been carried out with different configurations:
