The Labein technology centre performed a series of comparative tests to confirm the good acoustic results of Akustik+SylomerŪ. This centre is officially ENAC-certified and complies with the requirements of the ISO 140-1:1997 standard.

  PURPOSE OF THE TEST

The purpose of the test is to compare, in equal conditions, the acoustic isolation to air-borne noise of a false ceiling without anti-vibration suspensions (direct transmission) to a false ceiling with the new Akustik+Sylomer® suspensions.

The secondary endpoint is to compare the Akustik+Sylomer® to another suspension with the same size-specific characteristics using high-resilience natural rubber from our Akustik 4 45 shore A standard series.

Specimen used for the test

  TEST METHODOLOGY

The reports contain the results of the noise isolation test to airborne noise conducted according to the UNE-EN ISO 140-3 standard for a false ceiling with the following ceiling mounts:

  • Direct transmission (without anti-vibration suspensions).
  • Akustik 4 45 shore A.
  • Akustik 3+ Sylomer®30 Type B.

Besides these tests, the pink noise isolation index, R(A), was calculated, between 100 Hz at 5KHz, as the index specified by the basic building standard: NBE-CA 88 “Acoustic conditions”. The weighted noise reduction index (Rw) of the specimen, as well as the terms of adaptation to the C and Ctr spectrum, were obtained according to the UNE EN ISO 717-1 standard from the isolation curve.
