Figure 4 The bonding line 40 shown is provided, and an air valve 43 communicating with the inside of the inner liner is provided at one edge; the outer surface of the inflatable inner liner 4 is bonded to the inner tent fabric 1 and the outer tent fabric 2 respectively by adhesive 11; the inner surfaces of the first inner liner surface 41 and the second inner liner surface 42 of the inflatable inner liner 4 are respectively bonded with adhesive 11, sound-absorbing layer 31, damping layer 32 and sound-insulating layer 33 respectively, and the thickness of the inflatable inner liner 4 in the inflated state is 2cm-5cm.

[0020] This utility model also provides a soundproof tent containing the above-mentioned soundproof tent fabric.

[0021] Noise tests were conducted on tents using the tent fabric of this invention and tents using traditional double-layered rainproof tent fabric in the same park environment. With the same external noise level, the noise level inside the tents was measured, and the data are as follows:

[0022] When the external noise level of the tent is 50 decibels, the internal noise level of the tent fabric in the first embodiment of this utility model is 25 decibels; the internal noise level of the tent fabric in the second embodiment of this utility model is 23 decibels; the internal noise level of the tent fabric in the third embodiment of this utility model is 28 decibels; and the internal noise level of the traditional double-layer rainproof tent fabric is 45 decibels.

[0023] When the external noise level of the tent is 90 decibels, the internal noise level of the tent fabric in the first embodiment of this utility model is 43 decibels; the internal noise level of the tent fabric in the second embodiment of this utility model is 40 decibels; the internal noise level of the tent fabric in the third embodiment of this utility model is 46 decibels; and the internal noise level of the traditional double-layer rainproof tent fabric is 85 decibels.

[0024] Therefore, this utility model utilizes the sound insulation and sound absorption effects of the sound insulation protective layer and the air layer of the sealed space to form multiple sound insulation and protection effects, which can effectively prevent the transmission of sound inside and outside the tent.
