The noise of air-conditioning units and cooling towers exist in the same way, so the huge noise generated by air conditioners often affects the normal lives of nearby residents, and the style of the sound barrier of the air-conditioning unit has a direct impact on the noise reduction effect. In order not to increase the cost of the sound barrier project while improving the noise reduction effect of the sound insulation screen, the sound barrier style often adopts an arc shape, and the higher the sound barrier, the larger the shadow area, and the greater the sound attenuation. This is beyond doubt. However, if the sound barrier is too high, it may bring problems such as structure, environment and cost. Therefore, when designing the sound barrier, it should be adjusted according to the actual local situation to achieve satisfactory results. The following introduces the material characteristics of the "air-conditioning unit sound barrier", I hope it will be helpful to everyone!
