Abstract

Doors for sound insulated booths have a planar air passage e.g. 12 faced with sound deadening material through which ventilation of the booth takes place. <IMAGE>

Description

SPECIFICATION Sound insulating structures This invention relates to sound insulating structures.
Sound insulating booths are used for scientific and medical investigations and are conveniently constructed of preformed sound insulating panels.
In order to allow prolonged occupation of such booths by humans it is necessary to provide ventilation. Air ducts provided for this purpose are a source of possible sound transmission and they have been conventionally sound proofed by making them convoluted, lining them with sound proofing material and locating them in a unit secured outside the booth, the ducts communicating with the inside of the booth by means of ports in one or more panels, normally in the wall or ceiling of the booth.
Sound absorbing units of this type complicate the construction of booths because of the volume which they occupy and are vulnerable to damage during installation or through accident. The inlet to such units and the port leading into the booth must also be free from obstruction and this space is not available for other uses.
This invention comprises a door, which comprises a first air port in a first face of the door, a second air port in a second face of the door, the second air port being displaced from the first air port in the plane of the door, and an air passage in the plane of the door connecting the said ports which passage is faced over most and preferably substantially all of its surface by sound deadening material.
Doors according to the invention provide a very compact means of providing a sound insulated air transmission channel and the air gap between layers of sound proofing material in the door itself provides some protection against the transverse transmission of sound through it.
An additional advantage is that the space inside and outside the door has to be left free for access in any case and this form of the invention requires no additional space to be provided adjacent to the air ports.
The invention also comprises ventillated sound insulating booths which comprise doors as described above.
The booths may comprise panels which comprise a first air port in a first face of the panel, a second air port in a second face of the panel, the second air port being displaced from the first air port in the plane of the panel, an air passage in the plane of the panel connecting the said ports which passage is faced over most and preferably substantially all of its surface by sound deadening material.
Panels as described above can be formed as walls, ceilings or even if desired floors of sound insulating booths and need present no significant difficulty of installation as they can be adapted for joining to other panels in the same way as the other panels are themselves joined together.
If necessary means may be provided for propelling air through the vents which may take the form of a fan which is preferably located outside the booth. A fan suitably communicates with a vent passing through the panel as previously described.
One form of the invention will now be described with reference to the accompanying drawings of which Figure 1 shows an elevation of a door according to the invention and Figure 2 shows a vertical cross section through the door.
The door is provided with a handle 1 and hinges 2 and 3. An air inlet port 4 through the opposite face of the door is shown by dotted lines.
The door comprises an external metal face 5 which is turned over at its edges to define a recess into which the layer of plasterboard 6 is bonded. The inner face of the door is defined by a metal sheet 7 which is bent to provide a recess in which Rockwool sound insulation material is accommodated, the recess being bounded also by perforated plate 9. To the inner surface of the door is secured a panel 10 comprising further Rockwool sound insulation material which is faced by perforated sheet 11. A gap between sheet 9 and plasterboard 6 defines an air inlet channel and a gap between sheet 5 and sheet 7 at the top of the door defines an air exit port which may if desired be protected from falling dust by covering it with a layer of permeable fabric.
Air inlet port 4 communicates between the space inside the door and air channeL 12. It is faced with a decorative mesh 13.
The door abuts a door frame 1 5 on its inner surface thus leaving outlet 14 unobstructed and permitting passage of air to the external atmosphere.
It will be appreciated that an exit port may be provided through the layer of plasterboard 6 and the external sheet 5 if it is desired to use a door frame which would obstruct a port in the upper edge of the door.
Wall panels need be less robustly constructed than doors. A single layer of Rockwool or other sound insulating material faced with perforated sheet on both sides may in this case take the place of the assembly 9, 8, 7, 10 and 1 1 described above.
It is not essential that the whole of the air channel be faced with sound insulating material as described above. If necessary, metal struts may be provided underlying sheet 5 in the neighbourhood of the hinges 2 and 3 in order to give greater mechanical strength. Such struts may suitably be covered with plasterboard or other sound insulating material but the loss of sound insulating effect involved in omitting this protection is small.
Rockwool sound insulating material is a sound absorbing resin bonded mineral fibre material.
Rockwool is a trade mark.
