isolation rating.

Sound Insulation Boards are classified into air-borne sound insulation and vibrator y sound insulation. Air-borne sound insulation boards are used for insulating sound propagated in air. Vibrator y Sound Insulation boards are used for insulating sound propagation in rigid components such as monolithic reinforced concrete buildings.

Noise

There are two sound insulation types classified according to the categor y of civil engineering: building sound insulation and structure sound

There are three factors to generate and transmit noise: noise source, propagation path and receiver. Most adults can hear noise within the

insulation.

frequency range of 100 Hz to 5000 Hz. The frequency of conversation and common noises in buildings is basically 125 Hz to 4000 Hz. The wall's Sound Reduction Index, or SRI, refers to the level of sound insulation provided by a structure, partition or wall within the range of

125 Hz to 4000 Hz.

The building sound insulation can be approximately classified into indoor sound insulation and outdoor sound insulation according to the

Decibel The decibel (dB) is the unit used to measure the intensity of a sound. Since dB is measured on a logarithmic scale and not a linear scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB.

Sound Reduction Index (SRI) VS Sound Transmission Class (STC) The sound reduction index (SRI) is a measure of the reduction in the intensity of sound when it passes through part of a building; in other

sound insulation positions. For example, the indoor insulation includes sound insulation of walls, structure surfaces, ceilings and other characteristic building structures requiring sound insulation and sound insulation of underground buildings; the outdoor sound insulation mainly includes sound insulation of open-air walls and other outdoor sound insulation items.The building sound insulation can be classified into compound sound insulation and structure sound self-insulation according to the sound insulation methods. Compound sound insulation is a novel sound insulation method that all kinds of sound insulation materials are used for sound insulation. The sound insulation materials with different properties are used for sound insulation in a compound way by dint of respective properties to make full use of advantages of respective sound insulation materials to improve the overall performance of sound insulation and realize the effects of rigidflexible joint, multiple sound insulation layers and comprehensive protection.

words, the level of sound insulation provided. It is the difference between the sound intensity that hits one side of an object (such as a wall, door, window, partition and so on) and the sound intensity measured on the other side, expressed in decibels (dB).

When sound hits the surface of a material, some will be reflected, some will be absorbed by the material and some will be transmitted through it. By determining the SRI, the effectiveness of the element as an insulator (the amount of sound that it has prevented from passing from one side to another) can be assessed.

SRI is defined in the series of international standards ISO 16283 (parts 1-3). Standard testing methods, both in laborator y and field environments, have been established for measuring SRI. In the USA , the sound transmission class rating is typically used instead.

2. Structure sound insulation is a sound insulation method for structure sound self-insulation or blocking up sound propagation by adopting a certain form or method. For example, the sound absorbing cotton, the sound absorbing board and other materials are used to weaken the sound propagation path and change the range of sound propagation. (Such as highway noise barriers).

Damping Pads

F100 - Vibration Control and Sound Insulation Pads (Peel & Stick Adhesive on Both Sides)

F100B - Vibration Control and Sound Insulation Pads (Peel & Stick Adhesive on One Side)

The F100 Damping Pad is refined by taking the steady Asphalt molecules as the base materials and adding the heavy mineral powder and other sound absorbing particles. The obvious damping property can immediately change the resonance effect of the base materials to generate excellent wideband damping and sound insulation properties.

Resonance depends on the rigidity and thickness of the material and occurs on the point where the sound transmitted through the structure is matched with the natural frequency of sheet. The rigid light board type structures (such as gypsum boards, veneer boards, dr ywalls and hollow walls) generally generate the passive resonance, and the noise is propagated by the material properties and structures.

The F100 Damping Pad is suitable for the composite use of the sound insulation transformation boards in residences, hotels, clubs, KTV, nightclubs, recording studios, telecast halls and other sites and the damping, sound insulation and noise reduction of the industrial traffic equipment. It is generally regarded as the DIY multi-purpose sound insulation and damping composite material with highest cost performance.

F2000

Damping Features

Calculate the amount of damping paint F2000

When damping materials contact with vibrating objects, it will absorb vibrational energy in a certain degree. In this way, it makes the vibration into heat energy which results in making impact on vibration.

Impact from damping depends on time delayed by deformation from force of vibration. And because of this hysteresis, the recycle of tensile reaction produce internal consumption due to the need of overcoming internal friction.

F2000 is usually 1.5 to 2 times as thick as the substrate, related to amount, size and thickness of their materials used .The F2000 weight needed w(Unit: kg) is calculated as

Under the effect of sound wave, the F2000 will also play its damping performance causing the loss of sound energy, namely sound absorbing effect.

When sheet materials like plywood, hard board, gypsum board, asbestos cement are fixed onto a frame, together with closed air layer behind, they will be formed into resonating system. If there’s any motivated source, resonating phenomenon is bound to happen. In this system, resonance frequency is effected by proportion and tension of unit plank, and the air layer behind them. But in engineering practice, it’s really difficult to control the tension because it will be reduced as time goes by. Especially for nonmetal materials which are much less ductile than that of metal ones, they will be damaged permanently, shortening their life of usage. In this case, F2000 can

W = density x coating area x (substrate thickness x substrate thickness factor -1) In the formula, density units g / cm ³, F2000 density 1.2g/cm ³, coating area unit m², substrate thickness of units of mm, the final calculated in kg.

Application Reference for Yachts and Ships

At present, the attention to the speed is not paid any more for good yacht, but there are more requirements to high comfort and low noise. The ship noise not only affects the work, lift and physical health of crew themselves, but also affects the life of residents along the coast. The vibration source generating noise is one of roots causing the fatigue damage of the ship structure to impact the ser vice life and safety of the ship. Ship noise is irregularly formed by different frequency and different intensity sounds made when the equipment runs and made by the outside stormy waves clapping the hull, and includes airborne noise existing at the compartment part, structure-borne noise existing in the hull structure (namely, vibration) and water noise existing in the water medium around the hull. The progress of science and technology requires us to develop the study in noise and noise control theor y and method to improve human life and working conditions and create the comfortable acoustic environment.

The vibration damping and noise reduction technology is one of methods for effectively controlling structural vibration and noise, namely, the vibrator y mechanical energy is converted into the heat energy to be dissipated by utilizing the viscoelasticity of material, thereby achieving the purposes of vibration damping and noise reduction. The damping and noise reduction material plays an indispensable important role in ship vibration damping and noise reduction engineering application, particularly in compartment noise reduction, the satisfactor y effect can be achieved by laying the damping and noise reduction material and combining other noise reduction measures. The vibration damping and noise reduction technology is that a structure layer including the damping material is directly adhered to the surface of the structural component to increase the damping performance of the structural component and improve the structural damping loss factor, the structural vibration energy is dissipated by the cyclic tensile strain or shearing stress of the viscous-elastic material to exert the damping capability in vibration damping and noise elimination to improve the vibration resistance of the mechanical structure, reduce the noise of the mechanical equipment and enhance the dynamic stability of the structural and mechanical systems. The Damping treatment technology is particularly suitable for the vibration damping and noise reduction of ribs, boards, casings and other components.

Noise control is to control the generation, transmission and receipt of noise source by taking the corresponding technical measures to obtain the acoustic environment required by people. In the ship, the engine room, the deck and the passenger compartment should be treated in noise control. In the yacht, vibration and noise are the two sides of one entity. Besides the airborne sound radiated by the sound source, the structural vibration caused by the sound source will be propagated outside through the hull structures (such as deck, engine base, hull longitudinal material, partition plate, etc.), and the many mechanism noises are caused between the cabins, so that it is necessar y to reduce the noise from the noise source and reduce the vibration of hull structure to reduce the noise of cabin.

Application Reference for Railway Trains

Research shows that the vibration noise frequency for most of the high-speed train bodies is 513 Hz to 1615 Hz, the vibration noise caused by the skeleton structure of the train body is within the low frequency range of 5 Hz to 30 Hz, and the vibration noise mostly caused by the wallboards is within the low frequency range of 30 Hz to 300 Hz. The noise in the carriage is from the airborne noise generated when the train runs at high speed, the friction and impact sounds of the rails, the noise of each component in the carriage, etc..

Control the vibration and noise radiated by the train body, avoid the interior resonance, prevent or eliminate the interior resonance, adjust and design the inherent frequency of the train body, effectively utilize the sound absorbing material or control the track excitement vibration transmission system, and adjust the vibration property on the noise reflection system to improve the cavity resonance in the train. In the components of the train body, the vibration of plates mostly impacts the noise of train body, because the sound radiation efficiency of the plates is higher. To reduce the vibration of the plates, the reinforced ribs can be arranged for the plates to improve the rigidity, and the damping material can be additionally installed or the vibration damping material can be stuck to increase the vibration attenuation. In addition, the water based damping material can be sprayed on the plates to reduce the sound radiation efficiency and effectively reduce the noise. The experimental conclusion is that the sound insulation effect is best when the damping coating coverage is 3 kg/m².

More noise reduction and sound insulation measures should be taken on the structure and material in order to effectively improve the acoustic environment of the carriage, including improving the air duct structure to reduce the noise of the air conditioner, adopting the double-layer surface structure with high sound attenuation rate on the aluminum alloy train body, filling the vibration damping foamed resin in the truss between two surface layers for the room and the side wall, additionally mounting the vibration damping material on the carriage floor or installing the sound insulation steel plate on the floor, filling 50% foamed vibration damping material at the truss widening part on the bottom edge of the carriage side, etc.

In order to prevent the secondar y solid sound transmission of vibration and noise source from the bogie, the traction motor, the gear box, the diesel generator and the air conditioning unit to the carriage, the sound insulation material should be added on the nearby train body key structure to increase the sound insulation property of the train body structure, and the noise propagation path can be insulated by the vibration insulation, sound insulation and sealing measures. The vibration transmission between the vibration source and the train body can be obstructed by the elastic material and the damping material. The sound insulation performance of the interior ornaments can be improved by adding the vibration damping cushion and the damping adhesive. Those measures can weaken the noise transmitted into the train during the running process of the rolling stock.

For the metro rolling stock running in the tunnel, the double-layer vacuum glass windows should be adopted in order to prevent the noise from being transmitted to the carriage through the window glass on two sides of the rolling stock.

Application Reference for Armored Vehicles

The armored vehicle is the main militar y equipment for the future armored mechanized troops and will take the ver y important operational missions in the future war. In order to give full play to the operational effectiveness of the militar y hardware for the armored vehicle, the passengers of the armored vehicle must keep energetic and sensitive in a longer combat period, and it is necessar y to create a more comfortable living and operating space for the passengers of the armored vehicle. Currently, the noise pollution is generally serious inside the armored vehicle. The measurement results show that the maximum noise level in the Chinese track-laying vehicle can reach 120dB, and the noise level increases with the increase of vehicle driving speed. The solution of interior noise reduction for the armored vehicle has great significance to protect the fighters, improve the fighting capacity and give full play to the operational effectiveness. On the basis of modal analysis technology and related technology, the theoretical modal analysis result based on ANSYS modal analysis software and the experimental modal analysis result based on DASP (Data Acquirement and Signal Processing) software for certain armored car are compared, and the obtained modal parameter error analysis and the influence factor analysis showed the consistency of the two analysis results. Secondly, the internal sound field of the armored car is analyzed and researched by using the sound and vibration analysis software SYSNOISE. The result shows that the engine vibration is the main noise source for the passenger cabin of the armored car. The characteristic frequency for the vibration insulation and noise reduction properties in the armored car is obtained by analyzing the vibration and noise signals in the car by the frequency analysis method and the coherence analysis method; by the design of relative improvement measures such as the design of muffler and sound absorbing structure, in theor y, the internal noise in the armored car body is reduced, and the man-machine environment in the armored car is improved.

Continuous noise when the tank runs and impulse noise when shelling: the noise when the tank operates is classified into continuous noise (also called steady-state noise when the fluctuation is low) in running and impulse noise when the cannon fires. The noise magnitude is associated with the road condition, the running speed, etc., and the shot noise is related to the cannon type, the bomb type and so on. When the tank is started in situ, the total sound level is 100-109 dB, A sound level is 93-99 dB, and the noise intensity is increased with the increase of engine speed. See Table 1 and Table 2 for the intensity, distribution and duration of the operation noise and the shelling noise.The continuous noise is 107-112 dB (A) when the tank runs; the impulse noise in the tank is 167-172 dB (P) when the tank shells. The frequency of the operation noise is mainly the low frequency. See Figure 1 for the spectrum analysis results. The duration of impulse noise B is wider in the tank and is narrower outside the tank when the tank shoots, as shown in Table 2 and Figure 2.

After the tank runs or shells, the driver and the conductor have the temporar y threshold shift of hearing (Table 3) and recover after 24 hours. The noises are extremely harmful to the hearing, health, calling and operation of the passenger.

Application Reference for Industrial Pipings

In the life, the pipes are used for transporting all kinds of liquid and gas. Both the indoor noise and the outdoor noise radiated by the pipe have greater influence on people's life and work and damage people's hearing. The piping noises are mainly from the fluid machine noises and are related to the fluid pressure, the fluid speed and the power source for transmitting the fluid, and the intensity of the pipeline radiated noise is related to the piping structure, the material rigidity and density and the piping wall thickness.

The noise generated by the drainage pipeline generating the maximum noise reaches above 70 dB, and the noise from the industrial piping even reaches above 100 dB, so the sound insulation treatment of the pipes is of great urgency.

If the piping is coated with F100B - Vibration Control and Sound Insulation Pads (Peel & Stick Adhesive on One Side), the piping noise radiation will be effectively reduced. The ordinar y household drainage pipeline can be directly coated with F100B to meet the sound insulation requirement; before the use of F100B, the piping can be cladded with superfine glass wool and the mineral wool for industrial noise control, and finally the galvanized sheet is used as the shell protection faceplate, so that the high frequency and low frequency noise absorption can be increased to make its comprehensive sound insulation effect better.

the houses. The comfort is mainly expressed in the degree of quietness, and the functionality is mainly expressed in home theater, piano room, mahjong room and other function rooms. In order not to impact other residents and achieve better acoustic effect, it is necessar y to consider sound insulation treatment which cannot be ignored in the house construction preparation and using process.

Hotel Guest Rooms The customer satisfaction is the priority among priorities in the hotel management, and whether the customers can fall asleep in the quiet environment is the most important assessment criterion in the guest satisfaction sur vey. The sound insulation problem of the hotel guest rooms is one of the top three in the hotel preparation consideration factors and is the key indicator for assessing the hotel stars. The main considerations in sound insulation are the impact of entertainment function area on the guest rooms and the mutual impact between the guest rooms. According to the national standards, the sound in the acoustic environment of the hotel guest room must be lower than 40 dB, so it is

Standard Application Areas

particularly important to select a scientific and effective sound insulation scheme when the hotel is planned to be built and decorated.

(1) Type 0 standard is applicable for the areas with high quiet requirements such as sanitarial district, senior villa district, senior hotel district and

KTV Due to the pertinence of consumer groups, the locations of KTVs are mostly located downtown. The contradiction between the noise generated from KTV and the people's requirement for quiet environments is increasingly prominent.

Bars and Nightclubs In order not to influence the normal work and rest of the surrounding residents in the operating time, it is necessar y to perform the thorough sound insulation treatment to the bars and the nightclubs in the construction process. The high-volume sounds of the bars and the nightclubs can reach 110dB (A) (the energy is mainly concentrated at low frequency) when the bars and the nightclubs are in operation, the large amplitude sound pressure forces the floors, the walls, the suspended structures, the elevator shafts, the shearing walls and other components to vibrate and transmit the vibration to the components connected with them to further transmit to the whole building. The government mandatorily requires that the transmitted noise of the bars and the nightclubs shall not be higher than 40 dB in the normal operation (the indoor noise volume shall be lower than 110 dB). The related operating formalities shall be handled when the bars and the nightclubs reach the national environmental evaluation standards.

so on. The noise of the suburb and rural areas should be 5 dB according to the standard stricter than the type 0 standard.

(2) Type 1 standard is applicable for the living, culture and education areas.

(3) Type 2 standard is applicable for the living, commercial and industrial mixed area.

(4) Type 3 standard is applicable for the industrial area.

(5) Type 4 standard is applicable for the areas on two sides of the arterial roads in the cities and the areas on two sides of the inland navigation channel across the urban area. The background noise (referring to the noise level when the train does not pass through) limit of the areas on two sides of the railway trunk and secondar y lines across the urban area should meet the type 4 standard.

Note: Type 1 to type 4 standards are also applicable for the factories and the boundaries of the enterprises and institutions which may cause the noise pollution.
