Noise control technology and noise reduction scheme, Shenzhen Quelte Sound and Noise Reduction Engineering Technology Co., Ltd. specializes in noise reduction of mechanical equipment . With the rapid development of industry, the impact of noise on people's lives is more and more prominent. In life, the path of noise propagation is very complicated. Take the room between the equipment and the room next door as an example; the noise between the equipment is transmitted to the next room by four kinds of paths: 1. Noise is transmitted to the next room through the wall. 2. Noise is transmitted to the next room through the aperture on the wall. 3. The vibration of the machine frame between the equipments generates an outwardly propagating structure that enters the next room. 4. All of these noises are transmitted through the air, and the vibration of the noise source propagates along the structure of the house to form a solid sound. Therefore, noise control technology and sound insulation noise reduction scheme are divided into two categories: one is the isolation of solid noise, and the other is the isolation of airborne noise.

Vibration noise subtraction process using solid:

It is usually based on the survey and analysis of noise sources, distinguishing between primary and secondary, and adopting different sound insulation / isolation measures. For airborne noise. For the vibration of the machine equipment to stimulate the solid sound of the floor and the wall, rubber shock absorption, spring damping and other vibration isolation materials are needed to isolate the solid sound. For heavy and dense materials, such as reinforced concrete boards, which have good effect on isolating airborne noise, the effect on solid sound insulation is very poor. Similarly, rubber, foam and other materials with better solid sound insulation are used to transmit airborne noise. Isolation is also not effective. Therefore, the survey and analysis of noise sources is very important for the design of sound insulation solutions and the selection of materials.

Less vibration

Vibration means that the vibration source or sound source excites the vibration of the solid member. This vibration radiates outward in the form of elastic wave through the rigid connection of the foundation, plant floor, wall column, unit surface, etc., thereby generating solid sound, also called structural noise. The main parameters of vibration characteristics are: vibration frequency, vibration displacement, vibration speed and vibration acceleration. Commonly used shock absorbing products are shock absorbing damping rubber, spring damper, rubber cushion, damping platform and so on. The method of damping / isolation can be divided into active damping and passive damping according to the connection type of the source and the supporting source. Depending on the form of vibration, it can be controlled by solid vibration isolation and damping damping. The selection of damping materials should be based on actual operating conditions such as ambient temperature, source amplitude, weight, stiffness, and vibration frequency. After professional analysis to develop shock absorption technology solutions, choose the right shock absorption products.

Sound insulation for airborne noise :

Sound insulation

Sound insulation refers to airborne noise, which is made of sound-insulating / absorbent materials to block or enclose noise in a space. This control method is called sound insulation. Practical applications such as railway road noise reduction, production workshop sound insulation, machine equipment interval sound, office area interval sound, home floor and bathroom drain pipe sound insulation. Commonly used sound insulation measures include sound insulation cover, sound insulation room, sound insulation layer, pipeline sound insulation, sound insulation barrier and so on. The design of the sound insulation scheme needs to be designed according to the actual working conditions and requirements of the site such as: sound source type, noise level and frequency, environmental / environmental requirements, ventilation and heat dissipation requirements, noise reduction targets, etc., and appropriate sound insulation / absorption materials are selected.
