Fiberglass Isolation hangers as soundproofing products

Fiberglass Isolation Hangers
Fiberglass Isolation hangers are used for isolating noises of high frequency produced by equipment, ductwork, and piping which are suspended. The hangers have a molded, inorganic, and coded isolation pad made of fiberglass fixed to a load transfer plate made of steel and to a hanger bracket either welded or stamped. The isolation hangers will permit a misalignment of the support rod to the extent of 30° arc. The fiberglass pads are made from extremely small diameters, fused, annealed, and stabilized glass fibers which are tested with heavy overloading during manufacture, subsequently coated with a layer of flexible moisture-resistant elastic membrane. Fiberglass has a unique feature in the sense that its natural frequency is constant over a wide range of operating load, and also its stiffness increases in proportion to the load. Ideal isolation hangers made of fiberglass are available having capacities ranging from 250 to 900 lbs. (113 to 408 kg) in appropriate sizes having deflection of 0.18 to 0.27″ (5 to 7 mm). Fiber glass isolation hangers are suitable for situations where vibration is produced by suspended electrical or mechanical equipment, exhaust fans, piping, ductwork etc.
Fiberglass isolation hangers can be used for isolating any source of vibration of frequency of audible range, or noises which are suspended and located close to an area that need to be quiet. A typical instance of the use of the hangers for isolation of noise is the ductwork and piping systems in the construction of a building. Spring loaded fiberglass hangers are used for control of low frequency noise from sources such as overflying aircraft. Isolation hangers are ideal for ceiling systems where sound transmission loss is high.
Vibration isolators requiring maximum static deflection of not more than 0.27″(7 mm.) under working load conditions will have hangers comprising of molded fiber glass inserts which are pre-loaded and the load transfer plate fitted in a welded or stamped bracket made of steel.
The fiberglass insert is coated separately with moisture-resistant elastic, flexible layer. The insert shall be molded from glass fibers with fiber diameters not exceeding .00027″ (6.8 microns) and with a modulus of elasticity of 10.5 million PSI (738,223 kg/cm2).
The fiberglass vibration isolators shall have a constant natural frequency for the working load range of the equipment that is being supported. Vibration isolators shall have a code showing its load capacity.
The hanger bracket should be capable of taking an overload of 500% safety margin and also permit misalignment of supporting rod to an extent of 30 degrees angle but at the same time not allowing contacts between metals or electrical short circuits.
Isolation hangers are ideal for controlling noise and vibration being transmitted into a structure from suspended equipment, ductwork, and piping. Fiberglass isolation hangers shall conform to the deflection requirements as per the Vibration Isolation Schedule or as mentioned in the project documents for every application specified.

Fiber Optic Products acoustical products

Fiber Optic Products
An optical fiber is a transparent flexible cylindrical thin glass (silica) fiber. It is widely used as communications medium for transmitting light signals across considerable distances. The advancement of technology has enabled the light rays to be guided over a distance of 1 km through glass fiber with minimum sound losses (3.6%, 0.16 dB). Apart from the long distance it also it also enables higher bandwidths compared to normal copper wire. Optical fiber is not affected by electromagnetic interferences and has less transmission losses when compared to metal. Fiber is also used in illumination and many other applications which include fiber lasers and fiber optic sensors. Fiber optic products have brought in a revolutionary breakthrough in transmission technology. Fiber optic cables have replaced coaxial cables made of copper as the medium of transmission of electromagnetic waves for terrestrial communication. Applications of optical fiber can be found in tele communication, data communication and computer local area network.
Applications of Fiber Optic Products
Bobtail optical fiber connectors are termination type ready to use connectors for field applications. They are pre-polished and used for applications like LAN (Local Area Networks), field repair work, laboratory settings and testing. Field repair work time is drastically reduced by as much as 90%. Special tools are not required.
An optical time-domain reflectometer (OTDR) is used for estimating length of fiber, signal strength including including joint and connection losses.
Fusion splicers use electric arc to fuse and join two optical fibers. The connections thus made are non-reflective. Fibers can be aligned by any one of two methods: core alignment and V-groove alignment.
Attenuators are used to reduce the strength of an optical signal. They are generally used to test power limits of a network or to match signal strength to levels acceptable for working optical equipment.
There is no optical network without cabling. Simplex cable design has fiber coated with a PVC tight buffer. They are further jacketed together, by Kevlar yarn covering, and a PVC outer jacket. Duplex cable is similar to simplex cable except that it has fibers both for transmitting and receiving.
Fiber Optic Cable Assemblies are custom-made and become necessary when normal patchcord cable is not enough for providing connectivity in a project. Legacy connectors, multi-fiber and large-core fiber assemblies are some of the typical examples.
Cleaning the fiber optic connectors and cable is a very important part. Bottled Isopropyl alcohol is used to clean the fiber. This helps in trouble shooting your problems in fiber optic connection. Instead of spending money in replacing patch cords several times, cleaning with this liquid will help to improve the signal.
FIS Mechanical Splices are used for gripping fibers together. They also help in using special adhesives to achieve higher pull strength.
They are used as light guides in medical and other applications where bright light needs to be shone on a target without a clear line-of-sight path. Fiber optic products have found wide applications in decorative lamps, signs, toys, art and innumerable advanced technologies.

Acoustical Soundproofing Fabric gripper system wall panel assembly

Fabric Gripper System
Fabric gripper system is a wall panel assembly comprising of a frame, a flat insulating material called a filler, and the selected fabric which is stretched tightly on top of the filler. The fabric is clamped all around the edges of the frame by the fabric gripper jaws. The assembly fabric gripper system is then fixed to the wall on a hanger, in such a way that the assembly is easily removable. The assembly of the frame, fabric, and track are independent of the wall panel and therefore can be assembled on the wall or away from it.
A high impact resistant plastic frame is used as the fabric gripper system track for holding the selected substrate. A substrate is actually an insulating material and is also called “back material “or “core”. The edges of the fabric after being stretched aver the panel surface are tucked into the tracks and gripped firmly by the jaws. The loose edges of the fabric are inserted into the cavities of the channel of the track.
The fabric covering which is held tightly between the jaws can float freely over the panel face. This floating design has several advantages. This design helps to cover up any damages on the panels or painted surfaces which are behind the fabric cover. The seams and joint lines which are normally visible in other types of panel boards are nicely covered up in Fabric gripper system.
The fabric can be replaced any time without having to dismantle the entire assembly. Any repair or design change can be carried out easily because the fabric is not glued to the panel. You have to only release the grip of the jaws and remove the fabric and replace with new one. During replacement the substrate and track remain undisturbed. This saves time and money and besides the fabrics used are generally recyclable. Maintenance cost is reduced considerably.
Fabric gripper system is adaptable to different ambiences in the sense that the design, finish, color, etc., of the fabric can be chosen to match the interiors of any architectural demands. The system can be made to suit any size of ceilings or walls.

Engage Sound Control Specialists to Conduct an Audit of Your Soundproofing Requirements

In most environments and workplaces sound control is mainly considered. It is needed for providing a pleasant and safe environment for people to work and operate in. In the present world of technological advancement it is needed to consider soundproofing of an environment or noisy machine, and in most cases a soundproofing solution can be found.

Sound Control

Many techniques are involved in modern methods of soundproofing by means of which sound emitted from air pressure and hydraulic pumps, vibrating machines, bottling lines, conveyor belts, machine parts, and high speed tools can be reduced or eliminated. There can be application of soundproofing materials to the machine and its parts for absorbing sound caused by air emission, vibration, and various other sources for reducing the noise as nearby the source as possible. In other instances for enclosing a noisy area, soundproofing enclosures can be built and produce a solution for controlling noise that prevents the escape of noise into a larger area. Inside a soundproofing enclosure a whole machine can be set up, or soundproofing materials can be fitted in a room for containing the sound waves.

A special operation where there is emission of not only sound but also heat and damaging sparks is welding. There can be control of these nuisances too using specially designed welding curtains. Presently sound control is a specialized field of technology having many different solutions for soundproofing. There is a difference in each situation meaning that each environment is different. Two pieces of machinery having the same specification can be installed into two distinct environments. This creates two distinct noise problems. There are innumerable variables like walling, flooring, roofing, dimensions of the area the machine is kept in and more

Dog Kennel Grooming Salon Acoustics and soundproofing products

Dog Kennel/Grooming Salon Acoustics

Acoustic Surfaces has many different products that could all possibly lessen the noise in a dog kennel/grooming salon and all offer their own respective advantages and disadvantages. Some are washable, some are very economical, and some are customizable and decorative. The top three panels that come to mind are the Echo Eliminator, the Sound Silencer and the Fabric Wrapped Fiberglass panels. Each of these options offers a different advantage.

Echo Eliminator Panels

Of the three options the most cost effective is the Echo Eliminator panels. It is available in ten different colors. Made from recycled cotton fiber and usually left as it is which is somewhat similar to feel and look to a piece of felt. These panels are mostly installed onto the ceilings or walls with a spray adhesive or a construction adhesive. For mounting points some customers use grommets in the panels or also Velcro. Even though these panels are the least expensive, usually they have the least finished look. Depending on the room aesthetic and where the ceiling space or available wall is there they may work for you or not. The NRC rating of these panels is .80 (for the 1” thickness) which means that they are very absorbent.

Sound Silencer Panels

The Sound Silencer panels are available in 2’x4’ but absorb about 50% of the sound as either of the two other options. The great advantage this option has is the fact that these panels can be completely washed and can be utilized in areas that other panels will just not work. They can be attached to the ceiling or wall with adhesive.

Fabric Wrapped Fiberglass Panels

The Fabric Wrapped Fiberglass panels have the most finished look and have a little more absorbance than the Echo Eliminator panels. They are all customized offering the freedom of custom fabrics and panel sizes to utilize as the decorative facing. Since their production involves labor, they are also the most costly.

For knowing the number of panels that are needed, experts have suggested a thumb rule. That is 3% of the cubic volume of the room (height x width x depth) will give you the area to be covered by panels. This is a generic guideline and adjustments may be needed on the basis of the needs of a particular room.

Where you place the panels is entirely up to you and wherever they are placed in the room the same basic result can be got. The location of the panels does not make any difference to the acoustical result and functionality of the room. The area of panels installed relative to the size of the room has to be determined than them being put in specific locations.

Does Your Ceiling Fan Make A Lot Of Noise? How to stop the Noise?

Does Your Ceiling Fan Make A Lot Of Noise? Find Out Why
Have you not experienced the feeling when someone standing next to you keeps buzzing in your ear? It is natural that you will be irritated and you will lose the concentration in whatever work you are doing after some time. That feeling is exactly similar to the feeling that you will get when you are sitting under a fan that gives out a continuous buzzing noise.
Reasons for Fan Noise
There could be many reasons why a fan should be making unpleasant noise. To start with, we can say, that lack of proper maintenance and collection of dust may be one of them. Secondly, incorrect earthing and electrical faults may be other possibilities. Thirdly, the fan may be running at a very slow speed. Let us find out why the third reason should cause a problem. .
The motor of the fan is designed to run within a particular range of speed. The focus of the manufacturers is on the higher range of speed because fans running at higher speeds give out better air ventilation and more comfort by reducing perspiration. But, on the contrary a person feeling cold will in all probability switch off the fan completely.
However, there can be situations, when a person who is not comfortable without a ceiling fan and so would like to run the fan by reducing the power to the minimum. If the fan that is being used has been designed to run at prefixed limits, you may not have any problem. If there is a regulator on the fan to adjust the level of speed, you may try to choose a level that is so low that the motor starts giving out a buzzing noise. There is no definite solution to overcome this problem.
Possible Alternatives
The sensible thing to do is to identify that position of the regulator where the fan makes minimum noise when speed is reduced. You should not reduce the speed lesser than this level. Alternately, get a fan which has a motor having less power. Motors with higher power and range of speeds tend to malfunction when they are set to run at very low speeds at low power. That is why you can get over this problem by opting for a motor with less power. But it is well to remember that this suggestion may be successful only if you are planning to run the fan all the time at the lower speeds. In case you are particular to select a fan having provision to run at both low speed as well as high, it is clear that you will have to settle for either the performance of the fan or accept the sound pollution that will result.
Better fan designs are now available which can be run at lower speeds without much noise problems, but you may have to pay more. Also better maintenance like cleaning and oiling regularly may reduce the operating noise.

Diffusor Panel Acoustical Soundproofing products and panels

Diffusor Panel
A diffusor panel is more expensive because it is usually more difficult to build and design. There is some difficulty in integrating it into a room. They are rarely found in the average room but are commonly seen in recording studios and high end rooms.
Diffusion vs Absorption
A diffusor panel just absorbs sound waves and a panel as such can be placed wherever the overall room reverberation needs to be reduced and addresses the most damaging reflections. A point is quickly reached in many domestic rooms where no sound is heard. Problematic reflections are addressed by diffusors without absorbing their energy. They are an alternative to sound absorption since they do not remove sound energy but can be effectively used to reduce distinct reflections and echoes. In comparison to a reflective surface which causes reflection of most of the energy, in a diffusor, sound energy will be radiated in many directions. This leads to an acoustic space that is more diffusive. Also it is important that reflections are spread by a diffusor in time and also spatially. Another benefit is that when a small room is treated with diffusion it sounds bigger, while if absorption is used in treating a room there is a tendency of sound to be more controlled till it fades off.
Placement Considerations
You can place absorbers wherever you want in a room but the placement of diffusors is dependent on certain rules.
1. Minimum listening distance
At close range diffusors become inffective. The specific panel decides the minimum distance. Usually there is a requirement of 1m or more but where a wall behind is close to a listening position, a distance of .5m may be allowed by a low profile diffusor panel.
2. The impact of sound waves is reduced if before reaching the diffusor panel they have reflected off many boundaries.
3. Diffusors have a limited effective bandwidth.
4. Don’t overdo it!
Too much diffusion is likely to create imaging confusion.
Types of Diffusors
Mostly there are either 1D or 2D diffusors. QRD (Quadratic Residue Diffusor) is a common example. Since it is one among the simplest it is popular. A 1D QRD works in one direction and is very simple. A 2D QRD works in both directions. The Skyline diffusor is quite similar, which is essentially the same thing without the grid. Quite similar is the Skyline diffusor, which is basically the same thing without the grid.
Confusion over Diffusion!
Some panels are mistaken as dispersers while in fact they could be best described as scatterers. Panels featuring small pyramids or curves are not actual diffusors. More specular reflections are created by curved panels. They are similar to a curved mirror, while an actual diffusor panel is more like a matte painted wall.
