Embodiment Construction

[0033] The structure and composition of the animal noise stimulation box of the present invention will be described in detail below.

[0034] The animal noise stimulation box of the present invention has a double-layer structure, and the bottom between the inner and outer layers is placed on a vibration isolator to form a floating structure to eliminate low-frequency solid sound transmission through the building structure. There is a gap of more than 50mm between the inner layer sound insulation structure of the described noise stimulation box and the outer layer sound insulation structure, and the connections between the top ventilator and the ventilation and noise reduction pipeline are soft connections, so that the formation of sound bridges can be avoided. The vibration isolator is selected with its own natural frequency below 10Hz to eliminate the low-frequency solid-borne sound transmitted through the building structure.

Abstract

The invention relates to a noise stimulation box, which has a main function of providing a noise giving environment for experimental animals during noise stimulation. The noise stimulation box is implemented by a lightweight sound insulation component and a double-layer composite sound insulation structure in order to improve the sound insulation performance and meet the special requirements of the noise simulation box on ventilation, fireproofness, moisture proofness, corrosion resistance and the like. The noise stimulation box disclosed by the invention furthest ensures the strength stability and the minimum attenuation after a noise signal of a signal generator is output, furthest meets the requirements on normalization of noise stimulation models and provides an effective environment foundation for establishment of the noise-induced deaf animal models. The noise stimulation box relates to the field of scientific research of the experimental animals, sound wave barrier sound-absorbing materials, physical ventilation and the like and is suitable for establishment of various noise-induced hearing loss animal models and sound stimulation models as well as behavior surveillance of the experimental animals under the noise exposure.

Description

technical field [0001] The invention relates to the fields of scientific research on experimental animals, sound-wave blocking and sound-absorbing materials, physical ventilation, etc., and is applicable to the establishment of various noise-induced hearing loss animal models and acoustic stimulation models and the behavior monitoring of experimental animals under noise exposure. Background technique [0002] In the clinical and basic research of noise-induced deafness, animal experiments are required. After evaluating the auditory electrophysiology of subjects such as guinea pigs, rats, mice, etc., different noise stimuli (sound stimulation) are used according to different experimental purposes. The signal needs to be quantified and evaluated), and then conduct quantitative and qualitative detection and observation of relevant indicators on the subject (or after corresponding treatment), so as to obtain relatively objective statistical results. In the past, in the establish...
