A good reason for the sound effect of a bar

As everyone knows the bar audio frequency sound and has strong penetrating ability, if the control is not good, that the use of the best equipment, can not achieve the desired results, in fact, knowledgeable people, in the decoration under the foot work: the bar wave is common by a number of sound sources, several speakers have several sound sources, there are several spherical wave. In the way of transmission, speakers can transmit sound waves around the hangers, top beams, columns, walls, sewer pipes, doors and windows, and exhaust ports. It is necessary to carry out the necessary vibration and sound insulation from all points and surfaces, so that it is possible to meet the design requirements.

Bar speakers are usually placed on the beam or ground hanging around, playing strong music, sound and music have impact on the ground, the resonant frequency of Liang Zhuti or floor, and then to solid voice in the form of elastic wave to the residents upstairs room. Therefore, it is necessary to adopt the form of cushion damping system and increase the vibration damping hook, and isolate the vibration from the point sound source with the building connection point.

The speaker sound, high energy vibration of sound waves in the air waves, sound waves impinging on the wall column beam slab, which can penetrate the low-frequency part of cement, must be in the main beam, column and slab with elastic layer or a hollow resonance sound absorption layer, to eliminate high energy sound waves on the main beam, column and slab the impact bar through pipe straight thin-walled sonic family, therefore, must be on the upstairs tenants connected water pipes and re wrapped, the inner layer package damping layer, outer layer wrapped insulation layer, the middle soft connection must also increase.

If you do that, Congratulations! You must make the most basic request. Next, we must pay attention to the inevitable leakage of sound in the time when guests enter and leave the door. Therefore, a sound isolation gate should be added at the original gate distance not less than 2.5M, so that the first door of the guest is closed when the guest opens the second door. The air conditioner and exhaust port will bring out the noise in the process of discharging. We must add muffler, and eliminate the high and low broadband acoustic wave in muffler without affecting the normal exhaust.

The bar wall, sofa, seat should use more sound absorption materials to reduce the sound pressure of the indoor sound field, but also can adjust the tone of the volume of the bar more harmoniously and harmoniously. As long as we do these points, in addition to the debugging of professional technology, this is a few reasons for the sound effect of the bar!
