Description
Technical field
The present invention relates to the behavior monitoring of laboratory animal under fields, the foundation that is applicable to various noise induced hearing loss animal models and sound stimulation model and the Noise Exposure such as Laboratory Animal Science research, sound wave obstruct sound-absorbing material, physics ventilation.
Background technology
Noise deafness clinical with basic research in, need to carry out zoopery, to study subject as: after cavy, rat, mouse etc. carry out sense of hearing electricity physiological evaluation, adopt different noises to stimulate (acoustical signal requirement and assessment) according to different experiment purposes to it, study subject (or give respective handling after) carried out quantitative and qualitative detection and the observation of index of correlation, thereby obtain relatively objective statistics thereafter.The in the past foundation of experimental animal model, carry out at the noise stimulus outdoor scene of being everlasting, such as: the shock wave when utilizing aircraft engine sound, Canon launching, firecrackers sound etc., its defective is can't the accurate evaluation noise characteristic, animal model is built poor repeatability, animal is difficult to timely detection, and is time-consuming, and used experiment fees is expensive.For the variation that noise is stimulated the aspects such as the corresponding physiology (electric physiology) produce, pathology, nervous system is made scientific analysis and is judged that stable output signal quantification, Real-Time Monitoring and Scientific evaluation are particularly important.White noise or high strength pure tone that noise case of the present invention can noise stimulus signal acoustical generator occur are enclosed in certain space, reduce to greatest extent the decay of this stimulation, sound wave, improve its validity.
It is that noise when providing noise to stimulate to laboratory animal is to acoustic environment that noise of the present invention stimulates the major function of case.In order to improve sound insulation value, adopt light-duty partiting sound member and two-layer compound sound insulating structure to realize.Satisfying simultaneously above-mentioned noise stimulates ventilation, fire prevention, the protection against the tide of case, the specific (special) requirements such as anticorrosion.Noise of the present invention stimulates case to guarantee to greatest extent the stable and minimal attenuation of the rear intensity of noise signal output of signal generator.Farthest satisfied the requirement that the standard noise is stimulated model, be the foundation of noise deafness animal model, effective environmental basis is provided.
Summary of the invention
It is double-decker that animal noise of the present invention stimulates case, and the bottom between the ectonexine is mounted with on the vibration isolator, forms floating building structure, to eliminate the low frequency solid-borne sound transmission that transmits by the building structure.Described noise stimulates around the internal layer sound insulating structure of case and gap more than the 50mm is arranged between the outer sound insulating structure, and the top portion ventilation machine is with being connected of ventilating noise-elimination pipeline and is flexible coupling, and like this, can avoid forming overhead speaker.Vibration isolator selects self intrinsic frequency below 10Hz, eliminates the low frequency solid-borne sound transmission that transmits by the building structure.
It is double-deck 100mm steel construction sound insulation absorbent treatment that described noise stimulates case wall structure, and this structure has the oise insulation factor of 60-70dB (A).
Described noise stimulates the ectonexine of case that soundproof door is all arranged, and the twice soundproof door is designed to " sound lock " formula double-layer sealing structure, and there is the oise insulation factor of 60-70dB (A) at such structure two sects.
All have the sound insulation observation window on two sects, every observation window is and adopts the vacuum sound insulation window setting technique, and such structure has the oise insulation factor of 60-70dB (A).
The design of relevant ventilation, needing stimulates the top of case and the diagonal position of side at described noise, installs respectively noise elimination air channel and ventilation blower additional, to eliminate air power noise and mechanical noise, the junction in ventilation blower and noise elimination air channel all need be flexible coupling, the quadratic noise that causes to eliminate vibration.Described noise stimulates case inlet and outlet wind speed general control below 1.0m/s.
(1) ventilating noise-elimination design
Ventilating noise-elimination adopts impedance silencer, and its sound deadening capacity can calculate by following formula:
ΔL＝Φ(α)·C·h/S
In the formula: the extinction coefficient (relevant with used material) of Φ (α)-efficient resistance noise reduction sheet;
C, S-are respectively girth and the areas of section of silencing channel;
Effective noise elimination length of h-silencing channel.
Airduct is connected the front portion with main frame and adds muffler; Equipment Foundations and pipeline connect all does the shock insulation processing.
Cooperating simultaneously insulation works to do corresponding noise elimination noise reduction at inlet and outlet processes;
(2) design of ventilation wind speed
The wind speed size is the major reason that determines wind-force regenerated noise (silencer inefficacy), in order to control the wind-force regenerated noise, must keep watch speed control in certain limit, and in this engineering, wind speed must not surpass 1.0m/s.
Partiting sound member should in wider frequency range, have higher oise insulation factor.Most partiting sound members all wish it is the high member of light weight, oise insulation factor.If use the steel construction sound insulationg board, the high frequency acoustic capacitance is easily every falling, and medium and low frequency sound difficulty every, so need to wait measure to combine with sound absorption, improve its sound-insulation capability.What we taked is the clad steel sound-insulating structure, and described noise stimulates the sidewall of case and bottom surface, top to be the cavity that steel plate is made, and steel plate is electrostatic spraying inside and outside, fills out in cavity and rushes the porous fiber sound-absorbing material, and its average sound absorption coefficient is greater than 0.50.The airtight sound that do not leak in each member junction, edge joint position has sealing strip.Satisfying simultaneously described noise stimulates the specific (special) requirements such as the fire prevention of case, protection against the tide, anticorrosion.
Main material adopts the materials such as cold-rolled steel sheet, galvanized steel plain sheet, damping sheet, Sound-proof material, perforated sound-absorbing plate.
The high-quality defening effect of 60dB given that the pure noiseless sound of zoopery stimulates to acoustic environment, guarantee to greatest extent the signal output of signal generator, farthest satisfied the foundation that standard sound is stimulated model, be the reliability of animal experimental data, validity provides environmental basis.
It is 1400mm that described noise stimulates the case total height, suits very much to be placed on operating table surface or the desktop, and the handled easily personnel observe.Described noise stimulates case to divide top and the bottom, and top is high-power audio amplifier, built-in four loudspeakers.The bottom is the animal experiment space, and the cabinet wall both sides are provided with to sound sensor, video frequency pick-up head.Except the handled easily personnel observed, the Real Time Observation of operating personnel to animal behavior more satisfied in the setting of camera.In addition, described noise stimulates all adjustings of case all can pass through computation, and is convenient, quick, accurately.
The described noise of high oise insulation factor stimulates the case environment, adds high performance signal generator, and for the foundation of animal model provides reliable assurance, the accurate operation of calculator allows more science of data, and is reliable, greatly increased the repeatability that animal model is built.
