Abstract

An acoustic structural element which comprises a sound absorbing layer 2 and a perforated layer 3, with one side of the perforated layer being covered by a protective layer 4. Preferably, the protective layer 4 is waterproof and resistant to cleaning materials. The structural element may be used as a ceiling or wall panel.

Description

<p>1 2433521</p>
<p>ACOUSTIC STRUCTURAL ELEMENT</p>
<p>The invention relates to an acoustic structural element for reducing sound.</p>
<p>There are two main methods for reducing sound in a building.</p>
<p>The first method is to prevent the passage of sound into the building using a structural element which blocks sound such as a brick wall.</p>
<p>The second method is to absorb the sound using a structural element made from a sound-absorbing material.</p>
<p>With the former method, sound generated inside the building may be reflected off the structural element with the result that the element, whilst creating a sound reduction relative to the outside of the building, can still result in an unacceptable level of noise inside the building.</p>
<p>It is therefore preferable to use the second method.</p>
<p>One known method of absorbing sound is to use a structural element comprising a soft material such as foam or fibres.</p>
<p>A second known method is to use a structural element comprising an outer surface made from a hard material such as hardboard and/or a metal which is perforated to allow sound to pass through the material. The sound is absorbed by a sound-absorbing material such as fibre glass or mineral wool placed on the reverse side of the hard material.</p>
<p>There are a number of situations where neither of these solutions is</p>
<p>acceptable.</p>
<p>For example, in clean room and health care environments, sound reduction within and without areas such as hospital wards, operating theatres or research laboratories is of ever increasing importance.</p>
<p>The first of the known methods is not suitable for such environments because soft surfaces cannot stand up to the impact and general every day wear and tear found in these environments.</p>
<p>The second of the known methods is not suitable for such environments because, whilst the hard outer surface can stand up to the aforementioned wear and tear, that surface is perforated with the result that dirt will penetrate the surface and become embedded in the perforations and in the sound-absorbing layer giving an unacceptable level of cleanliness.</p>
<p>It is an object of the invention to seek to mitigate the above problems.</p>
<p>Accordingly, the invention provides an acoustic structural element comprising a sound-absorbing layer, and a perforated layer, one side of the perforated layer being covered by a protective layer.</p>
<p>If the perforated layer is covered by a protective layer, then it will not be possible for dirt to penetrate the perforated layer and become embedded in perforations and the sound-absorbing layer. The acoustic structural element will therefore be suitable for use in environments where cleanliness is of great importance, such as clean room and health care environments.</p>
<p>The perforated layer may be sandwiched between the sound-absorbing layer and the protective layer.</p>
<p>The protective layer may be substantially waterproof. Most cleaning chemicals are provided in liquid form, and having a protective layer which is substantially waterproof will prevent those cleaning chemicals from penetrating the perforated layer and being absorbed into the sound-absorbing layer, where they can result in degradation of the sound-absorbing layer as well as a health hazard.</p>
<p>The protective layer may be resistant to cleaning materials so that it does not deteriorate on exposure to such materials.</p>
<p>The exposed surface of the protective layer may be substantially planar.</p>
<p>This means that there will be no depressions in which dirt can accumulate.</p>
<p>The structural element may be a ceiling panel or a wall panel.</p>
<p>The invention will now be illustrated by way of example with reference to the following drawing: Figure 1 shows an exploded view of an acoustic structural element according to the invention.</p>
<p>Figure 1 shows an acoustic structural element 1 comprising a sound-absorbing layer 2, and a perforated layer 3, one side of the perforated layer 3 being covered by a protective layer 4.</p>
<p>The sound-absorbing layer 2 may be made of any suitable sound-absorbing material such as mineral wall or a fibre glass blanket.</p>
<p>The perforated layer 3 may be made of any suitable material such as steel or aluminium. Usually, 3O5O% of the perforated layer 3 will be covered by perforations, and the perforations will usually have a diameter in the range of 2.5 to 4 millimetres.</p>
<p>The protective layer 4 is made of a waterproof material which is resistant to cleaning materials. Any suitable such material may be used, for example vinyl film. The protective layer 4 may be coated onto the perforated layer 3 during manufacture of that layer 3 or may be applied after manufacture of that layer 3 by any suitable means such as an adhesive.</p>
<p>The perforated layer 3 is sandwiched between the sound-absorbing layer 2 and the protective layer 4. As* mentioned above, the protective layer 4 may be joined to the perforated layer 3 either during or after manufacture of that layer 3. The sound-absorbing layer 2 may be joined to the other two layers 3,4 by any suitable means such as an adhesive.</p>
<p>As shown in figure 1, sound is able to pass through the protective layer 4, for example via sound path 5, but any liquid such as a cleaning fluid, which is applied to the structural element 1, for example via liquid application path 6, is not able to pass through the protective layer 4. Accordingly, any such liquids will not be able to penetrate the perforated layer 3 and become absorbed in the sound-absorbing layer 2.</p>
