For KTV sound insulation problems, whether it is the owners or decoration companies, more or less have to take into account some of the problems, such as KTV insulation materials prices, KTV noise insulation materials, what, which good, and so on. The following Xiaobian briefly introduced KTV insulation materials to buy it.
· KTV sound insulation material purchase
In the process of buying KTV noise boards, it is difficult for you to use ordinary methods (such as naked eye observation, hand touch) and experience to judge the sound insulation performance of the soundproof board. The key is that the KTV insulation board must be built into the wall before it can feel or measure the amount of sound insulation. If the sound insulation wall is not up to the expected result, it is almost impossible to remove the wallboard and return it to the manufacturer. In this case, either accept the status of wall sound insulation is not ideal, or take remedial measures. Therefore, in order to avoid wasting your money, time and effort, it is very necessary for you to master some basic knowledge of choosing noise boards.
In order to improve the sound insulation of KTV wall and ceiling obviously, it is difficult to achieve the ideal effect only relying on ordinary building materials. For example: in the 100 light steel keel on both sides of the nail a 12 mm thick keel gypsum board, the cavity is filled with rock wool, wall insulation effect of about 35 dB; if the nail on both sides of the two pieces of gypsum board, wall insulation effect increased to about 39 db.
Generally speaking, you should pay attention to the following when you buy KTV noise boards. The 1. wall insulation target whether new or old wall insulation, wall insulation transformation, all need a clear requirement of sound insulation, the sound insulation wall to reach the number of decibels, and then follow the wall insulation to choose the economy, and the development of appropriate insulation board wall insulation scheme.
· Ktv sound insulating material; sound insulation principle
The size of the sound barrier is related to the structure and nature of the sound insulation component and the frequency of the incident wave, and the sound insulation function of the same component may vary greatly with respect to the sound of different frequencies. When sound waves through different damping characteristics in the wall, the air medium is caused by multiple reflections of acoustic, acoustic attenuation occurs, and the air layer elastic and additional absorption effect, the vibration attenuation ability greatly.
Ktv insulation materials follow the law of conservation of mass “ ”, material quality large single KTV per unit area for better sound insulation, high frequency noise of low frequency noise effect, the effect is not significant; frequency is reduced by half, the transmission loss to drop 6dB; to improve the sound insulation effect, the quality is doubled, the transmission loss increases 6db.
· Ktv sound insulation material; sound insulation target
The acoustic design of sound insulation of scientific and reasonable structure, selection of high quality and inexpensive KTV insulation materials and with the guidance of professional and technical personnel to complete the operation of KTV sound engineering, relevant departments of environmental protection after the completion of testing successfully reached the national standard. At the same time, in order to ensure the KTV sound insulation effect to achieve the desired target, the best limit for owners of friends to reduce noise management costs.
About the KTV sound insulation material related information, for everybody introduced here, hoped this article to you to be helpful. If you still have anything you don’t understand, you can pay attention to our family network. We will answer your questions as soon as possible.
