Description
The utility model belongs to sound shield technology field, specifically a kind of detachable board-like audiometric room that is applicable to scientific research, hospital's testing human hearing.
Audiometric room is the indispensable clinic of the ear-nose-throat department of various big hospital, and the audiometric room that present hospital is adopted, its structure generally all is to adopt brick mix structure or reinforced concrete structure to be built into the closet of a sealing, and then be provided with metallic shield net and some sound absorption materials at the internal layer of closet, simply fit up again, this audiometric room belongs to totally enclosed fixed buildings, it is indoor to eliminating solid conduction and air transmitted weak effect, atmosphere draught-free, contrast underproof reaching more than 90% by state specified standards.
The purpose of this utility model provides a kind of metal plate type structure and with the detachable board-like audiometric room of air flow system.
The purpose of this utility model is achieved in that it comprises box body, the soundproof course of sealing, it is characterized in that adopting dismountable steel plate to be connected into a box body sealing and that have door, be evenly distributed with the spring that prevents solid conduction in the bottom of box body, on the box body of steel plate layer, inwardly be disposed with air layer, soundproof course, air layer, absorbent treatment, also be evenly equipped with the block rubber of supporting separately in the air layer between steel plate layer and soundproof course, soundproof course and absorbent treatment, be respectively arranged with air intake and air outlet in the top and the bottom of box body.Using method of the present utility model is consistent with existing audiometric room with effect.
The side that the utility model also is included in box body is provided with a glass window, and this window needs 3-5 layer sheet glass.
The utility model is owing to adopt the audiometric room box body of steel plate as sealing, and this box body promptly has good acoustic shielding function, has good electro-magnetic screen function again, but also has increased the utilization rate of the usefull space; Communicate with the box body fresh air inlet by air-conditioning system, can be transferred to desirable temperature in the audiometric room.The utlity model has detachable, removable, be convenient to install, be convenient to advantages such as carrying, long service life; Also have rational in infrastructure, pattern is attractive in appearance, characteristics such as easy to operate, safe and reliable.
The utility model is described in further detail below in conjunction with accompanying drawing
Fig. 1 is a kind of mounting structure schematic diagram of analysing and observe of the present utility model
Fig. 2 is an another kind of structural representation of the present utility model
By shown in Figure 1, its concrete structure is: adopt dismountable steel plate to be connected into audiometric room box body 2 sealing and that have door 9 (layer structure of door is identical with the layer structure of whole box body), be evenly distributed with the spring 12 that prevents solid conduction in the bottom of box body 2, on the box body 2 of steel plate layer, inwardly be disposed with air layer 3, soundproof course 4, air layer 5, absorbent treatment 6, at steel plate layer and soundproof course, also be evenly equipped with the block rubber 11 of supporting separately in the air layer between soundproof course and the absorbent treatment, be used for suppressing solid conduction and air transmitted, top and bottom at box body are respectively arranged with air intake 7 and air outlet 10, this air intake 7 joins by the outer air-conditioning of air intake passage 1 and box body, the spacing of air conditioner and air intake is at least more than 2.4 meters, and also soundproof course and absorbent treatment will be installed in this air intake passage of 2.4 meters 1.Be provided with the window 8 of a four-layer glass sheet in a side of box body.Above-mentioned soundproof course generally adopts gypsum plank, benzene plate, wood based panel to make; Acoustical board is generally selected rock wool, cotton, the sound absorption cloth making of sound absorption for use, and it has played sound insulation and has absorbed the effect of internal noise.What be also noted that is that the audiometric room box body of steel plate layer is 0.1 meter apart from the distance of indoor wall at least.The function of this audiometric room and mode of occupation are consistent with existing audiometric room.
Fig. 2 is another embodiment of the present utility model, and the profile of its structure is less than previous example, but the annexation of its structure is consistent with Fig. 1, and just air intake passage is arranged on the rear portion of chamber body.Be followed successively by among Fig. 2: steel plate box body 1, air layer 2, soundproof course 3, air layer 4, absorbent treatment 5, and air intake passage 6, window 7, entrance hole 8, door 9 and be arranged on the floating spring 10 of building of box body bottom.
The soundproof room ambient noise test that the audiometric room of Fig. 1 carries out through medical acoustic metrology testing research master station of the Chinese People's Liberation Army, its test report sees the following form: the maximum ambient sound arbitrarily downgrade (GB/T 16403-1996) that allows of 1/3 octave band when the typical general earphone is made gas, bone-conduction tests
A weighted sound pressure level is closed the air-conditioning 19.0 19.5 soundproof room external environment noise 55-658 (A) that turn on the aircondition in the soundproof room
| The centre frequency of 1/3 octave band (Hz) | Maximum ambient sound Lmax (is benchmark with 20 μ l ' a) the test pure tone frequency scope 125～8000Hz 250～8000Hz bone conduction 500～8000Hz that arbitrarily downgrades that allows | Test value | |
