Abstract
The invention discloses an audiometric room wall body capable of regulating sound absorptivity. The audiometric room wall body is provided with a plurality of sound absorption bodies with identical shapes, and each sound absorption body can rotate around a pivot to regulate the sound absorptivity of the audiometric room wall body. Therefore, according to the audiometric room wall body capable of regulating sound absorptivity, which is disclosed by the invention, by rotating the sound absorption bodies, the area of the audiometric room wall body changes, so that the sound absorptivity of an audiometric room is changed and the different requirements of different test products on the reverberation time are met.
Description
Technical field
The present invention relates to a kind of audiometric room, relate in particular to a kind of audiometric room body of wall of regulating acoustic absorptivity.
Background technology
Audiometric room is a kind of acoustic measurement environment, and its inner reverberation time is determined by the acoustic absorptivity of its wall covering.The body of wall of audiometric room generally adopts sandwich construction, adopts steel plates, aluminium sheet, plank, damping sheet, aluminium-plastic panel and various sound absorption materials at present more, and interior facing is selected the sound absorption material that sound absorbing capabilities is good as far as possible.For different test products, require its reverberation time also different, but the audiometric room on prior art, its acoustic absorptivity just sets when building, and can't regulate, and so just gives and needs the user of test different product to bring significant limitation.So be necessary to design a kind of audiometric room body of wall of regulating acoustic absorptivity, to meet the different reverberation time requirements of different test products.
Summary of the invention
The object of the invention is to for above-mentioned defect of the prior art, a kind of audiometric room body of wall of regulating acoustic absorptivity is provided, it can meet the different reverberation time requirements of different test products.
For achieving the above object, the present invention has adopted following technical scheme: a kind of audiometric room body of wall of regulating acoustic absorptivity, it is characterized in that: described audiometric room body of wall arranges a plurality of identical shaped acoustic(al)absorbents that have, and each acoustic(al)absorbent rotor rotates to regulate the acoustic absorptivity of audiometric room body of wall.
In addition, the present invention also provides following attached technical scheme:
The shape of described acoustic(al)absorbent is regular triangular prism.
Described acoustic(al)absorbent comprises bottom surface and turning cylinder is set, and described turning cylinder is located thereon on the line of centres of bottom surface and is mounted to body of wall.
Described acoustic(al)absorbent is made by damping material, and its optimal material is a kind of of sponge, polyester fiber or glass wool.
The angle that described acoustic(al)absorbent rotates is between 0 ° to 360 °.
Than prior art, advantage of the present invention is: this audiometric room body of wall arranges a plurality of identical shaped acoustic(al)absorbents that have, and each acoustic(al)absorbent rotor rotates to regulate the acoustic absorptivity of audiometric room body of wall.So, can change the area of body of wall, thereby change the acoustic absorptivity of this audiometric room by rotating acoustic(al)absorbent, meet the different reverberation time requirements of different test products.
The accompanying drawing explanation
Fig. 1 is the stereogram corresponding to the audiometry wall of the acoustic absorptivity regulated of preferred embodiment of the present invention.
Fig. 2 is the stereogram corresponding to the audiometry wall of the acoustic absorptivity regulated of preferred embodiment of the present invention.
Fig. 3 is corresponding to the acoustic(al)absorbent of preferred embodiment of the present invention and the assembling stereogram of turning cylinder.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
Shown in Fig. 3, corresponding to the audiometric room body of wall of preferred embodiment of the present invention, it is mainly used in absorbing sound.Described audiometric room body of wall 1 is provided with the acoustic(al)absorbent 4 that a plurality of shapes are identical, and on each acoustic(al)absorbent 4, a turning cylinder 7 is set, and turning cylinder 7 is mounted on audiometric room body of wall 1.
Particularly, the shape of above-mentioned acoustic(al)absorbent 4 is regular triangular prism, and it is made by damping material, and its optimal material is a kind of of sponge, polyester fiber or glass wool.Turning cylinder 7 passes bottom surface 6 on acoustic(al)absorbent 4, and overlaps with the line of centres 14 of bottom surface 6 on acoustic(al)absorbent 4.Two ends and audiometric room body of wall 1 that turning cylinder 7 exposes bottom surface 6 on acoustic(al)absorbent 4 are fixedly connected, and acoustic(al)absorbent 4 can rotate around turning cylinder 7, and the angle of its rotation is between 0 ° to 360 °.When any one side 10 of whole acoustic(al)absorbents 4 parallel with the external surface of audiometric room body of wall 1, and when the upper bottom surface 6 of acoustic(al)absorbent 4 and any incline 9 expose the external surface of audiometric room body of wall 1, the surface area maximum of this audiometric room body of wall 1, so acoustic absorptivity is for the highest, its acoustic absorptivity can reach 80%.Stir acoustic(al)absorbent 4, make it around turning cylinder 7, carry out the pivot rotation.When any one side 10 of acoustic(al)absorbent 4 parallel with the external surface of audiometric room body of wall 1, and the upper bottom surface 6 of acoustic(al)absorbent 4 and any incline 9 are housed in audiometric room body of wall 1 when interior, the surface area of this audiometric room body of wall 1 is minimum, so acoustic absorptivity is minimum, its acoustic absorptivity can reach 20%.
It is pointed out that above-mentioned preferred embodiment is only explanation technical conceive of the present invention and characteristics, its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
Claims (5)
