Abstract
The invention discloses a sound-absorbing wedge of a sound attenuation chamber. The sound attenuation chamber comprises a sound-insulation wall and the sound-absorbing wedge arranged on the sound-insulation wall. The sound-absorbing wedge comprises a vertical part and a top part connected with the vertical par, wherein the connection part between the top part and the vertical part is circular-arc-shaped. Therefore, the connection part between the vertical part and the top part forms smooth transition, the uncertainty and the irregularity on sound reflection of the sound-absorbing wedge are relieved, and further, the sound absorbing performance of the sound attenuation chamber is improved.
Description
Technical field
The present invention relates to a kind of sound-absorbing wedge of anechoic chamber.
Background technology
The anechoic chamber is widely used in the acoustic measurement on the products such as machinery, electronics and Medical Devices at present, and it can be used as medical audiometry diagnosis room, language recording room, Shop floor control chamber or noise testing chamber.Therefore, to the requirement of anechoic chamber's sound absorption qualities than higher.
With reference to Fig. 2, existing anechoic chamber comprises sound-proof wall body 10 and the sound-absorbing wedge 12 that is installed in sound-proof wall body 10 inboards.And rectangular design is adopted in the cross section of sound-absorbing wedge 12 on overall structure, promptly forms a right angle between the top 14 of this sound-absorbing wedge and its vertical portion 16, thereby causes the uncertainty of sound reflection to increase, and causes the irregular reflection of sound.So, be necessary to provide this improved.
Summary of the invention
The objective of the invention is to provides a kind of sound-absorbing wedge of improved anechoic chamber to above-mentioned defective of the prior art, and it can improve the sound absorption qualities of anechoic chamber.
For realizing the foregoing invention purpose; The present invention has adopted following technical scheme: said anechoic chamber comprises sound-proof wall body and is installed on the sound-absorbing wedge on the said sound-proof wall body; Said sound-absorbing wedge comprises vertical portion and the top that is connected with said vertical portion, it is characterized in that: the junction between said top and the said vertical portion is circular-arc.
In addition, the present invention also provides following attached technical scheme:
Said top is circular-arc.
The sound-absorbing wedge global sections of said anechoic chamber is for falling " U " type.
The sound-absorbing wedge of said anechoic chamber is processed by damping material.
Than prior art; The invention has the advantages that: the junction between its top of sound-absorbing wedge of the present invention and the vertical portion is a circular arc; Thereby reach a level and smooth transition, improved its uncertainty and scrambling, improved the sound absorption qualities of sound attenuation room sound reflection.
Description of drawings
Fig. 1 is the schematic cross-section after the sound-absorbing wedge corresponding to the anechoic chamber of preferred embodiment of the present invention is installed on sound-proof wall body.
Fig. 2 is the schematic cross-section after the sound-absorbing wedge of anechoic chamber of the prior art is installed on sound-proof wall body.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical scheme of the present invention is done further nonrestrictive detailed description.
With reference to Fig. 1, comprise sound-proof wall body 1 and be installed on the sound-absorbing wedge 3 on the said sound-proof wall body 1 corresponding to the anechoic chamber of preferred embodiment of the present invention.The cross section of above-mentioned sound-proof wall body 1 is a rectangular design, and said sound-absorbing wedge 3 is installed on the inwall 7 of sound-proof wall body 1.
Said sound-absorbing wedge 3 is processed by centrifugally glass-wool or other damping materials, comprises vertical portion 32 and the top 34 that is connected with said vertical portion 32.Junction 36 between said top 34 and the said vertical portion 32 is circular-arc.Simultaneously; Said top 34 also is circular-arc; The sound-absorbing wedge 3 of said like this anechoic chamber is " U " type that falls at global sections; That is being connected between its vertical portion 32 and the top 34 reach a level and smooth transition, thus improved its uncertainty and scrambling to sound reflection, improved the sound absorption qualities of sound attenuation room.
It is pointed out that above-mentioned preferred embodiment is merely explanation technical conceive of the present invention and characteristics, its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (3)
1. the sound-absorbing wedge of an anechoic chamber; Said anechoic chamber comprises sound-proof wall body and is installed on the sound-absorbing wedge on the said sound-proof wall body; Said sound-absorbing wedge comprises vertical portion and the top that is connected with said vertical portion, it is characterized in that: the junction between said top and the said vertical portion is circular-arc.
2. the sound-absorbing wedge of anechoic chamber according to claim 1, it is characterized in that: said top is circular-arc.
