ANTIVIBRATION - ACR-FM "ACRTOOLS"

ACR - FM

• IMPACT NOISE REDUCTION
• WOODEN FLOORS
• IMPROVED SOUND INSULATION OF LIGHT PARTITIONS

Α new insulation system, the floor pad isolator ACR-FM, has been developed to reduce the impact noise of wooden floors. Impact noise refers to sound produced when a short duration impulse, such as a footfall, acts directly on a structure. The ACR-FM pads, are useful for the reduction of noise coming from upstairs to down stairs. Also, they are useful for improvement of insulation of light weight partitions.

DESCRIPTION

ACR-FM is produced based on a deep research in National Τechnical Uniνersity of Αthens.

The floor pads consist of metallic and elastic parts which are connected accordingly and as a result it prevents the creation of acoustic bridges. The elastic part consists of a specially designed non aging material providing maximum sound insulation. The metallic parts are protected by a special anticorrosion treatment.

ACOUSTIC TESTS

An exceptionally high WEIGHTED ΝΟRΜΑLΙSΕD IMPACT SOUND PRESSURE LEVEL (Ln'w = 53 dB) was measured at the Acoustic Laboratory of National Technical University of Αthens in accordance with International Standard ISO 140-6 and ISO 717-2. It should be noted that it was measured without the use of the pads Ln'w and the value was 66dB. Therefore a remarcable reduction of 13dB can be achieved whilst using the ACR-FM pads.
