9. Therefore Metrotile is seeking a tile design with a smooth exterior and yet the same noise emission properties as the conventional grained tile Metrotile Europe NV commissioned TNO TPD to conduct rainfall and impact noise measurements on various tile designs in order to investigate which type of noise control measure will be most promising A special measurement set up was designed and built for this purpose It is described in chapter 2 Results are shown in chapter 3 and discussed in chapter 4 Finally conclusions are drawn in chapter 5 TNO report DGT RPT 040015 April 28 2004 4 13 2 1 2280 Measurement procedure Rain and hail falling onto a tile have different excitation mechanisms Raindrops are relatively light non rigid bodies whereas hail is a solid body with a higher impedance Therefore two separate measurement procedures were applied Test roof A test roof was installed in a reverberant room The dimensions of the test roof are shown in figure 2 1 The roof was mounted at an angle of 30 degrees In total 6 prefabricates of 8 tiles were installed on the test roof The structure was closed by wooden panels The acoustic quality of this test rig is shown in appendix This 15 of importance in order to be able to clearly distinguish the noise radiation of the tiles in both directions A fixed microphone was installed inside the test building and a rotating microphone was installed in the reverberant field of the reverberat
10. a double walled tile the thin air layer trapped between the two tiles increases the damping of the structure It is to be expected that the damping can be increased some more if tiles with unequal thickness are used for the double walled tile For hail noise the effect of increasing damping is smaller but still 4 6 dB A is achieved Changing outer tile texture The outer texture of the tile affects the contact area both for a rain drop and for a hail stone This could explain the additional noise reduction besides the effect of higher damping TNO report DGT RPT 040015 April 28 2004 12 13 5 Conclusions and recommendations Currently the single painted tiles are put on the market as an alternative for the grained tiles Complaints were made concerning rainfall noise No complaints were made for conventional grained tiles This is consistent with the measurement results which show that for heavy rain the difference in noise emission between these two designs is about 7 dB A Application of the felt layer on a plane tile results in a decrease of about 5 dB A 2 dB A additional noise reduction for both rainfall and hail noise would result in the same amount of noise emission as the grained tiles So then the noise problem is expected to be solved The incorporation of a thin felt layer as a free damping layer on the backside of the tile looks promising for Metrotile because of its ease of production Further research could indic

17. the tile for hail excitation However for rainfall noise doubling the tile results in a noise reduction of 5 dB A This can be expected from acoustic theory This illustrates that the nature of the excitation mechanism of the tile has a large effect on the noise production and success of design changes Doubling of a grained tile results in only 2 dB A noise reduction This 1s possibly due to a relatively heavy coated grain layer The additional mass effect of thickness doubling is inferior Increasing damping Blank tiles are lightly damped plate like structures even when point fixed to the ridges with screws By introducing additional damping in the form of a thin felt layer glued on the backside of the tile a reduction of 8 dB A is measured for rainfall noise This 1s the same reduction as measured for a 2x0 3 double walled tile The noise reduction obtained with the glued felt layer is very high since the felt layer is light and possesses no bending stiffness This indicates that the blank tiles have light damping This is illustrated by the fact that a painted tile already gives 3 dB A noise reduction relative to an unpainted tile For a very lightly damped structure it 1s relatively easy to increase the damping However once the total damping is high it is hard to increase the damping further Both for rainfall and hail noise there is no difference between a tile painted on the top side and painted on both top and backside For
