Description
Technical field
The present invention relates to a kind of noise elimination laboratory facility, particularly a kind of testing window.
Background technology
Noise elimination laboratory is not only a special experimental laboratory of acoustical testing, and is the important composition portion of test system
Point, actually it is also one of acoustic test equipment, and its acoustical behavior index directly affects the precision of test；Noise elimination laboratory
Major function is to be provided for acoustical testing between a free found field space or Half free sound field, and its sound absorption efficiency quality is for disappearing
Free found field performance height after sound laboratory is built up is very crucial.
The noise elimination laboratory now used, it is provided with the soundproof door of disengaging, but it will be evident that the sound absorption efficiency of soundproof door is more
Less than noise elimination laboratory wall, this can cause the free found field performance in whole noise elimination laboratory to reduce, therefore, some pursue height
Free found field performance, the noise elimination laboratory of high test effect can be set large-scale (or perhaps integral type) at soundproof door more
Testing window, and in order to ensure to test effect, together with the periphery of testing window can pour with noise elimination laboratory wall more, also therefore meeting
The installation of the influence testing window of high degree simultaneously limits test article and the disengaging free degree of personnel.
The content of the invention
In view of the above-mentioned problems, the invention discloses a kind of testing window.
Specific technical scheme is as follows：

Embodiment
To make technical scheme become apparent from clearly, the present invention is described further below in conjunction with the accompanying drawings,
Any scheme drawn to the technical characteristic progress equivalencing of technical solution of the present invention and conventional reasoning each falls within guarantor of the present invention
Protect scope.
A kind of testing window as depicted, including sound insulation module 1 and installation frame 2, it is characterised in that the installation frame
2 are made up of the frame unit 3 of different size one by one, and the sound insulation module 1 is installed on installation frame 2 by bolt；
The sound insulation module 1 includes module housing 4 and the damping sound-insulation board 5 and silencing cotton 6 that are filled in module housing 4,
The module housing 4 is made up of upper shell 7 and lower house 8, and the upper shell 7 and lower house 8 are rectangular, and interconnect,
The length and width for the rectangle that upper shell 7 is in is all higher than the length and width for the rectangle that lower house 8 is in, and the institute of upper shell 7
The difference of the length for the rectangle that the length for the rectangle for being in is in lower house 8 is D1, and the width for the rectangle that upper shell 7 is in is with
The difference of the width for the rectangle that housing 8 is in is D2；The damping sound-insulation board 5 being filled in module housing 4 is glued by resin
It is connected on the inwall of module housing 4, the silencing cotton 6 being filled in module housing 4 is filled in the sky of the composition of damping sound-insulation board 5
Intracavitary；
The frame unit 3 includes unit housings 9 and the damping sound-insulation board 5 and silencing cotton 6 that are filled in unit housings 9,
The unit housings 9 are in square tube type, and its section is square, the two open ends of unit housings 9 and in lead to, it is described to be filled in cell enclosure
Damping sound-insulation board 5 in body 9 by resin bonding on the inwall of unit housings 9, the noise reduction being filled in unit housings 9
Cotton 6 is filled between damping sound-insulation board 5；
The square length that the section of the unit housings 9 is in is D, the D ＞ D1, and ＞ D2；Unit housings 9 with
By connecting plate 10, bolt connection between unit housings 9, test hole 11 square one by one is formed, the connecting plate 10 is in L
Shape, its both ends are provided with bolt hole 12, and its middle part is provided with fixing hole 13；
The test hole 11 is rectangular, and its length and width is consistent with the length and width for the rectangle that lower house 8 is in,
More than 2 times of the thickness for the rectangle that its thickness is in by lower house 8；Sound insulation module 1 is symmetrically distributed in the two of installation frame 2 two-by-two
Side, the insertion of lower house 8 are tested in hole 11, and upper shell 7 then passes through the framework list of fixing hole 13, bolt with forming installation frame 2
Member 3 is fixedly connected；
Further, the resin is polyurethane resin；
Further, the upper and lower ends of the sound insulation module 1 are equipped with folding lift-pull handle 14.
As illustrated, the testing window in the present embodiment is installed at the soundproof door in noise elimination laboratory, (soundproof door is relative to disappearing
For sound laboratory wall, its sound absorption efficiency is not high, to strengthen sound absorption efficiency, sets testing window, and the periphery of testing window need to be with
Wall is bonded or poured connected), as shown in figure 5, installation frame is combined into having multiple test holes by frame unit
Quadra；Sound insulation module, which is correspondingly installed on, each and every one tests at hole；
According to test approaches, complete Jing Yin test and reverberation measurement can be divided into；First, when carrying out complete Jing Yin test, installing frame
Left blank (as shown in Figure 5) in the middle part of frame, import and export and use as feed inlet and outlet and personnel, wait article to be measured to be sent into noise elimination laboratory,
The installation (as shown in Figure 6) in the middle part of installation frame is being carried out, frame unit and sound insulation module individual are smaller and light, installation difficulty
Low, for more existing integral type large test window, the testing window of the present embodiment possesses greatly just in the complete Jing Yin test of progress
Profit；Secondly, when carrying out reverberation measurement (as shown in Figure 5), directly left blank (between soundproof door and testing window in the middle part of installation frame
Set away from realizing), you can reverberation measurement is carried out, without separately making testing window up to specification, has not only saved manufacture
The time of different size testing window and occupation of land is put, while also considerably reduce the manufacturing cost of testing window.
Meanwhile the application method of the polyurethane resin referred in the present embodiment is as follows：1st, in advance by polyethers or polyester polyols
Alcohol presses 1 with polyisocyanates, water:0.25:2 mass ratio mixing, is made mixture A；Then by foaming agent and foam stabiliser
By 1:0.35 ratio mixing, it is anti-form-1-chloro-3,3,3 ,-trifluoropropene to obtain foaming agent described in auxiliary agent B, the foam stabilization
Agent is silicone oil；Then, when carrying out the bonding of damping sound-insulation board, in advance by auxiliary agent B coated in upper enclosure inner wall and lower house
Wall, then by mixture A brushes in upper enclosure inner wall and lower house inwall, and quickly stir and uniformly coat, finally directly will
Damping sound-insulation board is covered in upper enclosure inner wall and lower house inwall, is waited 10~15 seconds, and the bonding of damping sound-insulation board is completed, and is hindered
One layer of polyurethane foam is produced between Buddhist nun's sound insulationg board and upper shell, lower house, is favorably improved acoustically effective.
Meanwhile the upper surface for the module that insulates against sound can add installation wedge absorber, strengthen acoustically effective.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can readily occur in,
It should all cover within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection domain of claims
It is defined.
