What is BS EN 16487 - Test code for suspended ceiling’s sound absorption about?
BS EN 16487 specifies additional necessary information on how to carry out efficiently and under standardized conditions the determination of the sound absorption coefficients according to EN ISO 354- “Measurement of sound absorption in a reverberation room”. BS EN 16487 specifies the additional requirements of the sound absorption measurements and the operating and mounting conditions that should be used for the test.
The results obtained are used for design calculations with respect to room acoustics and to convert frequency-dependent sound absorption coefficients into a weighted sound absorption coefficient αw, according to EN ISO 11654.
Note 1: Observe that all demands in EN ISO 354 still should be fulfilled.
Note 2: BS EN 16487 is not applicable for suspended ceiling kits according to EN 13964.
Who is BS EN 16487 - Test code for suspended ceiling’s sound absorption for?
BS EN 16487 on suspended ceilings are useful for:
- Civil engineers
- Researchers of survey
- Construction industries
- Maintenance department of building
- Architects
- Manufacturers of suspended ceilings products
- Testing laboratories of sound absorption
Why should you use BS EN 16487 - Test code for suspended ceiling’s sound absorption?
A suspended ceiling is one that is suspended from or has a perimeter trim that is directly fixed to the load-bearing structure (floor, roof, beam, and walls) at a distance from the floor or roof above it.
For sound absorption measurements of suspended ceilings, BS EN 16487 specifies the Round Robin Test (RRT). This will enable you to create figures for measuring reproducibility, as well as to incorporate additional and more specific instructions.
Overall, BS EN 16487 provides the calculation of the single number rating w, which will help you to indicate the sound absorption capability of suspended ceiling membranes in CE marking and labelling under EN 13964.
