Bar and Nightclub Noise Control with acoustical soundproofing products
Bar and Nightclub Noise Control
Bars and nightclubs are generally places where people meet, relax, and make merry. The ambience is very important for such places and can make a lot of difference to their ability to encourage their customers to visit the bars or night clubs again and again. There is a lot of entertainment in a night club that include dancing and casual bars which prompt conversation between guests. Noise levels in the bars and night clubs is a worry to owners of the joints, the people living around and last but not the least, the law enforcement. There are limits on the sound level from nightclubs that can be tolerated.
There are two objectives in making a bar or nightclub soundproof. The first important one is reducing the level of noise created by loud music and customers that can be heard outdoors and in neighboring homes and other establishments. Secondly, owners of the clubs would like to improve the ambience inside with better quality of acoustics.
Reducing the Amount of Noise Leaking Out
To prevent the noise from escaping a night club it is necessary to isolate the place with better sound transmission control methods. So the aim is to target not only all the openings and gaps, but also ceilings, doors and walls. Even without treating all sources of escape of noise, you can achieve partial improvement. For minimizing sound transmission, many products are available in the market which can be installed by yourselves.
One option for restricting sound transmission is to build an additional wall surface leaving a gap with the first wall. Sound waves will weaken in the gap and won’t be able to pass through the second wall surface. The base for the second wall surface can be created by applying a layer of a soundproofing material like vinyl on the first wall over the full surface and then the second wall surface can be built by fixing a drywall layer on top of horizontal furring strips. This technique of adding density and a discontinuity (air gap) will effectively stop sound transmission.
Sound can also escape through windows and ceilings. Windows can be sealed with double glazing, sealants etc. Depending upon the uniqueness of the club and the ceilings, special false ceilings with acoustic panels can be installed on drop grids.
Improving Quality of Acoustics Inside
Other than controlling sound transmission leaking out, many owners of cubs also want to enhance the quality of acoustics inside the bars. The blaring music and noisy conversations which are typical of nightclubs and bars and reverberating sound from the number of surfaces inside the club can affect the ideal sound levels and mitigate acoustical quality. You can choose from several acoustic materials to minimize reverberations. There are foam panels, free hanging baffles, and urbane suede panels available in colors to match with existing décor.
The right treatment will depend on the purpose of the project and the uniqueness of each project. It is advised to hire an experienced consultant before implementing any soundproofing decisions so that all issues are addressed.
How does room construction materials affect sound?
How does room construction materials affect sound?
Unbeknownst to a majority, the materials used for constructing and decorating a room plays a pivotal role in controlling the level and quality of sound in the room.
Have you ever been to a public felicitation or any program where you had to perk your ears to understand what the speaker was saying because the sound was muffled and unclear? Or you went to watch a movie in a cinema hall and the sound system was killing your mood because of echoes? These are day to day examples of how inadequate or excessive use of acoustic materials with different properties affect the quality of the sound.
When sound incidents on a surface, a part of it is absorbed by the material and a part of it is reverberated off the surface. The reflected waves bounces off of other surfaces until it dies down. The amount of sound reflected or absorbed depends on the acoustical properties of the material. Different materials possess different acoustical properties. Some of the materials are good absorbers of sound and some others reflect sound. Materials that absorb sound causes the sound to come out as dull and dry whereas the materials that reflect sound makes it sound muddy, and blurry. The usage of materials in the right way will result in the good quality of sound. Let us consider an example and analyse how this works.
Wood as such is not a good absorption material and hence its sound insulation properties are not particularly good. Dense wood structures reflects sound. This property of wood can be a boon or curse depending on how we utilize it. A person unaware of this property of wood may end up using it in such a way that it causes unwanted reflections reducing the quality of the sound but by the one who understands, the reflection property of wood can be utilised in concert halls and musical instruments. By using multi-layered constructions or placing porous absorption materials behind a wooden board or panel in addition to an air gap, sufficient amount of insulation can be achieved in wooden buildings. This applies to every material. Materials like cushions and curtains absorb sound whereas reverberative materials like wood and glass reflect sound until it dies off. They should be used in a way that they absorb sounds to avoid echoes.
To put is simply, the type and amount of materials and even the positioning of them by an interior designer affects the quality of sound in a room. A skilled architect or interior designer will consider the acoustics of the building or room in mind while working. Accordingly, materials and furnitures will be selected for the construction suiting its purpose. On the other hand if you are moving to a new space and you want to alter the acoustics of the building, changes can be made accordingly with the help of an acoustic engineer.
Acoustic engineers are professionals with knowledge in the field of acoustic engineering and soundproofing. ‘Acoustical surfaces’ is a leading company in the field of soundproofing and noise control. With over 25 years of experience and 400 different materials to be chosen from, customer satisfaction is with no doubt, guaranteed.

Noise control practices for architectural acoustics
Architectural Solutions for Noise Control
Noise control practices for architectural acoustics include: inter-room noise transfer reduction, interior sound reverberation reduction, and exterior building skin augmentation. In the instance of construction of new (or remodeled) apartments, hotels, condominiums, and hospitals, many cities and states have strict building rules with acoustical analysis requirements for protecting building occupants. Considering exterior noise, the exterior acoustic environment needs to be measured for the codes for determining the performance standard needed for exterior building skin design. The architect works with the acoustical scientist for arriving at the best cost-effective means for creating a quiet interior (normally 45 dBA). For designing the building skin the elements of most importance are usually: glazing (double pane design, glass thickness, etc.), roof material, perforated metal (used internally or externally), caulking standards, exterior door design, chimney baffles, attic ventilation ports, mail slots, and mounting of through-the-wall air conditioners.
First Type of Interior Sound
Considering generation of sound within the building, transmission is of two principal types. Firstly, the travel of airborne sound through floor or walls and ceiling assemblies can be produced from either mechanical noise inside the building systems or human activities in close by living spaces. Human activities might include noise from amplified sound systems, voice, or animal noise. Mechanical systems are boilers, elevator systems, generators and trash compactors or refrigeration or air conditioning systems. Aerodynamic sources include pneumatics, fans, and combustion. Control of noise for aerodynamic sources includes pneumatic silencers, quiet air nozzles, and quiet fan technology. Because many mechanical sounds are naturally loud, the principal design element requires that the wall or ceiling assembly meets certain performance standards, which allows considerable reduction of the sound level reaching occupants.
Second Type of Interior Sound
Impact Insulation Class (IIC) transmission is the second type of interior sound. Airborne transmission does not cause this effect, instead from sound transmission through the building itself. The perception of IIC noise most common is from occupants’ footfall in living spaces on top. Noise of low frequency is easily transferred through the buildings and ground. It is more difficult to reduce noise of this type, isolating the floor assembly above must be considered or lower ceiling must be hanged on resilient channel.
Both of the transmission effects mentioned above may originate either from occupants of the building or from building mechanical systems such as plumbing systems or heating, elevators, ventilating and air conditioning units. In some instances just the best available quieting technology needs to be specified in the selection of such building hardware. In other instances for controlling vibration shock mounting of systems may be needed. For plumbing systems specific protocols are developed, particularly for water supply lines, for creating isolation clamping of pipes inside building walls. Considering central air systems, baffling any ducts that may transmit sound between different building areas is important.
ADA Compliance became compulsory in soundproofing interiors
ADA Compliance
ADA Compliance became compulsory when the Department of Justice (DOJ), USA, brought out an Act of the Government of USA, known as the Americans with Disabilities Act (ADA) Standards for Accessible Design in September 2010. These standards stipulate that all data related to electronic and information technology must be accessible to those people who have disabilities. The ADA is different from Section 508 regulations, which seek to amend the Rehabilitation Act of 1973 and is applicable to all sections of information technology, including computer hardware, software and documentation. The ADA standards are also applicable to commercial and public entities that have “places of public accommodation” which includes the internet. The DOJ is presently considering specific regulations but in the meantime, DOJ has stated that any discrimination on the website will not be tolerated.
Coverage of ADA
All Americans having disabilities and their families, friends and caregivers
Private companies employing more than 15 or more employees.
Businesses organizations working for the betterment of the public.
All state and local government agencies
How Does a Company Comply With ADA?
The ADA compliance rule encourages organizations to exercise self-regulation as far as implementation of accessibility standards are concerned till the Department of Justice has completed the development of regulations to provide specific guidance to the entities covered by the ADA. Organizations are encouraged to use the WCAG 2.0 level AA guidelines as a guide on how to become accessible until the DOJ defines the regulations.
The accessibility training is tailor-made to prepare you for ADA compliance formalities and is handled by experts in accessibility. The training is in different in formats, like on-site classes and webinars.
Many technical and general accessibility topics are covered. Some of them are:
Accessibility 101, W3C WCAG 2.0 guidelines, HTML5 & ARIA, Section 508 compliance standards,
Software Accessibility, Accessibility for Agile Development, Word, InDesign, PowerPoint & Excel Accessibility, and Mobile accessibility
An accessibility certification is a testimonial which briefly states at what level of compliance of section 508 Standards or WCAG guidelines you are on a definite date.
Those developing websites for mobiles or applications for mobile phones or for tablets must ensure that your iOS, Android and Windows applications should meet the Section 508, WCAG 2.0 and ADA accessibility requirements.
It is recommended that you update your application certification or website minimum once a year.
Web Accessibility Conformance Evaluation for ADA Compliance
A statement of accessibility is issued after a web accessibility conformance evaluation which certifies the level of your commitment to accessibility and makes available the details to users with disabilities. This will help them take considered decisions about the level of your ADA compliance and your products which in turn will enable you to improve your sales and customer loyalty.
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.
Application
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.
Specification
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.
Conclusion
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.
Design
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.
Advantages
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.
Applications
The fabric gripper system of sound insulation is ideal for offices, board rooms, conference rooms and training rooms. They are also used widely in cinemas, hotels, recording studios, and convention centers.
System Features
Fabric gripper system does not sag because of its excellent grip. The surface is very even and smooth. The parts inside like tracks are not visible. Tracks are available in different designs. System length is 6 feet which is the standard. Fabric gripper systems are available in lengths of 1300 mm. Double widths are also possible. The fact that the appearance of the interior of any space can be changed without much expenditure by only replacing the fabric makes fabric gripper system very popular.
