For ktv noise protection, whether it is the owner or the decoration company, more or less have to consider some issues, such as ktv sound insulation material prices, ktv sound insulation materials , which are good and so on. The following small series briefly introduces the ktv sound insulation material to buy it.
·The purchase of ktv soundproof materials
In the process of purchasing ktv baffles, it is difficult to determine the sound insulation properties of the baffles using ordinary methods (such as visual observation, hand touch) and experience. The key is that the ktv insulation board must be built into a wall before it can sense or measure its sound insulation level. If you build a sound insulation wall and the wall insulation is not as effective as you expected, it is almost impossible to remove the wall panel and return it to the factory. In this case, either accept the unacceptable status of the wall insulation or take remedial measures. Therefore, in order to avoid wasting your money, time and energy, it is very necessary for you to properly grasp the basic knowledge of purchasing sound insulation boards.
In order to significantly improve the sound insulation of the ktv wall and ceiling, it is difficult to achieve the desired results by relying only on ordinary building materials. For example, a 12 mm thick gypsum board is nailed on both sides of the 100 light steel keel, and the rock wool cavity is filled with rock wool. The wall sound insulation effect is about 35 decibels. If two gypsum boards are nailed on both sides, the sound insulation effect of the wall is improved. To 39 decibels or so.
In general, when purchasing ktv baffles, you should pay attention to the following matters. 1. The soundproofing target of a wall, whether it is a new soundproof wall or an old soundproofing of a wall, requires a relatively clear sound insulation requirement, that is, the sound insulation amount of the wall needs to reach the number of decibels, and then according to the sound insulation target of the wall. Choose economical, suitable sound insulation panels and develop wall soundproofing solutions.
·Ktv soundproof material soundproof principle
The amount of sound insulation is related to the structure and properties of the sound insulation member and the frequency of the incident wave. The same member may have very different sound insulation functions for sounds with different frequencies. When acoustic waves sequentially pass through walls and air media with different characteristics and damping, multiple reflections of acoustic waves are generated and attenuation of acoustic waves occurs, and the vibration capability is greatly attenuated due to the elasticity of the air layer and additional absorption.
Ktv sound insulation material follows the "law of conservation of mass," single layer ktv sound insulation components per unit area of ​​high quality materials, the better the sound effects for high frequency noise, low frequency effect is not significant; frequency is reduced by half, the transmission loss should be reduced 6db; but to improve sound insulation In effect, the quality is doubled and the transmission loss is increased by 6db.
·Ktv soundproof material soundproof target
Through scientific and reasonable acoustic design of sound insulation structure, the selection of inexpensive KTV sound insulation materials and the guidance of professional and technical personnel to complete the ktv sound insulation project, after completion of the relevant environmental protection departments to carry out the test smoothly to the national standard. At the same time, to ensure that the ktv sound insulation effect achieves the desired goal, the best limit is to reduce the noise control cost for the owner's friends.
Information about ktv soundproofing materials was introduced here for everyone. I hope this article has helped you. If you still have anything you don’t understand, you can follow our website and we’ll get back to you as soon as possible.
