Embodiment Construction

[0019] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 with figure 2 As shown, the glass sound insulation performance comparison device of the present invention can simultaneously test the sound insulation performance of sound insulation glass and non-sound insulation glass, including a signal generator 1, a loudspeaker 2 and two sound level meters 3 with spectrum analysis functions. The device 1 is connected to the speaker 2 through a wire or bluetooth and can output sound signals to the speaker 2. It is characterized in that: it also includes a sound insulation test box 4, one side of the sound insulation test box 4 is open, and it is set in the sound insulation test box 4. The first sound insulation board 5, the first sound insulation board 5 is parallel to the open side of the sound insulation test box 4 and divides the sound insulation test box 4 into a reverberation zone 41 an...

Abstract

The invention relates to the technical field of glass performance testing, especially simultaneous testing of sound insulation of sound-insulating glass and non-sound-insulating glass, and particularly discloses a glass sound insulation comparing device. The glass sound insulation comparing device comprises a signal generator, a loudspeaker and two sound level meters with spectrum analyzing functions, and further comprises a sound insulation testing box, a first sound-insulating plate and a second sound-insulating plate, wherein the first sound-insulating plate partitions the sound insulationtesting box into a reverberation zone and a testing zone; the second sound-insulating plate partitions the testing zone into a first testing zone and a second testing zone; the loudspeaker is fixed into the reverberation zone; a first window and a second window are formed in the first sound-insulating plate; the two sound level meters with the spectrum analyzing functions are mounted inside the first testing zone and the second testing zone respectively. The glass sound insulation comparing device can simultaneously test the sound insulation of the sound-insulating glass and the non-sound-insulating glass, so that more intuitive sound insulation comparison is achieved and the sound insulation testing efficiency is improved; the glass sound insulation comparing device can reduce interference of the external environment on a testing process and a testing result, so that the testing result is more accurate.

Description

Technical field: [0001] The invention relates to the technical field of glass performance testing, in particular to simultaneously testing the sound insulation performance of sound-insulating glass and non-sound-insulating glass, in particular to a glass sound-insulation performance comparison device. Background technique: [0002] At present, the sound insulation performance test of glass is mainly carried out in the sound insulation laboratory. The sound insulation laboratory is composed of two reverberation chambers with a volume of not less than 50 cubic meters and an anechoic enclosure. The test equipment mainly includes noise generators, filters , power amplifier, microphone, loudspeaker, sound intensity probe, dual-channel analyzer, computer and sound pressure, sound intensity calibrator, etc.; when testing, randomly select three flat samples and cut them into specified sizes, or make the same material 1. For the flat test sample of the specified size made by the same...
