Measurement of drum noise
EN 16205 / EPLF 021029-3

In daily life one can suffer from different types of sound in a home. Two of them (which are sometimes mixed-up) have the origin of noise through steps on a floor.

People speak of impact noise when one refers to the noise that is perceived in the underlying space and about drum noise when one means the noise in the same room. In Dutch this is called "loopgeluid", in French this is "bruit des pas sur les planchers" and in German "Gehschall".

Overall, not too much attention is paid to drum noise, although everyone experiences it almost every day. In the past, more carpets were used as floor coverings. With these soft materials the drum noise is considerably lower than with the modern floor finishes with hard materials such as tiles, laminate or concrete. When stepping on a hard floor, the noise level (depending on the footwear and the number of people) can be considerable.

Since a few years, suppliers of floor coverings have been busy publishing an internationally valid standard that regulates the measurement of drum noise in a laboratory. This in order to compare the different floors with each other. It started with a guideline from the so-called EPLF group (association of laminate suppliers). They developed the EPLF NORM 021029-3 in 2004. This test guideline (no official ISO or EN standard) describes how the drum noise of a floor has to be evaluated. For this EPLF measurement method, the eco-scan noise lab has been accredited since 2009. In 2013, a first version of the European standard EN 16205 was published. This standard describes a different measurement method to evaluate the drum noise on floors. It is expected that the EN 16205 will eventually "replace" the most commonly used EPLF measurement method.

Since June 2018, the eco-scan noise lab is able to carry out accredited measurements for the NBN EN 16205 method.
