Sound Insulation with our acoustic foam offer the perfect blend of technical specifications and eye-pleasing aesthetics. We offer three different piece sizes and four color options in order to meet your acoustic needs.

Acoustic Wedge Foams

Acoustic absorption is the key to this line! Go with our 2" Wedges when you're trying to tame frequencies in smaller areas. These are our most popular seller and work great with most acoustical needs. Our 3" Wedges are better at absorbing low-end frequencies than the 2" version. Medium sized areas will appreciate the acoustic accuracy of the 3" wedges. 4" Wedges are best for larger sized areas with bass control issues. If you need maximum acoustic control and sound accuracy, 4" is the size for you.

 Acoustic Pyramid Foams

In general, the pyramids are better at diffusing sonic anomalies than their wedge counterparts. By having 4 sides exposed, as opposed to 2, sound absorption is reduced while sonic accuracy is heightened. Pyramids will produce a much richer, more complete sound than wedges. Go with the larger sizes when battling against the undesirable sonic effects that bigger rooms pose.

We design the Acoustic Curtains to provide a degree of sound absorption within the space in which they are used. Noise levels can be typically reduced by as much as 20 dB-A with a properly designed curtain enclosure Often used in performing arts spaces they not only provide a variable acoustic environment for different applications but control excessive reverberation in halls with very reflective surfaces.

All material is chemically treated to create a DFR (Durably Flame Retardant) fabric that will withstand a number of dry cleanings. This meets the requirements of BS5867: Part 2: B which is the British Standard for flame retardant fabrics used for the manufacture of curtains.

The degree of sound absorption depends on the weight of the fabric used, the depth between the curtain and the wall and the degree of pleating.

ACOUSTIC PERFORMANCE

We offer Acoustic Treatment for DG Rooms. The Noise is control by providing Acoustic lining on walls & ceiling, all ordinary doors / shutters are to be convert in to sound proof doors. The proper Air ventilation system is designed to allow the maximum aspiration and cooling airflow required so the engine does not overheat. Axial flow fan of required size & numbers provided for proper Air ventilation. Acoustic louvers, splitter & Insulated ducts are provided to suppress the noise where required.

ESPL Acoustical Enclosures  are designed to control noise levels of engine driven sets, compressor, and pump systems.  The performance of a standard enclosure will reduce the equipment's noise level to 75  dB(A) or less, 3 feet from the enclosure and 5 feet above grade level.  Enclosures can be custom designed to reduce equipment noise to 50 dB(A) at 5 feet.

Our acoustic enclosure reduces noise and meets the ISO 14001 norms for environment. It also prevents the excessive noise and their harmful effects. In this regard various techniques for noise control are available.

All  enclosures are designed in modular panel form for all types of industrial machinery and processes, incorporating inspection panels, windows and doors as required for easy access and periodic maintenance And  truly modular. The several basic elements of the system - standard panels, window panels, and door panels - are removable and we can relocate on other location.

The wall construction of 100mm (4") thick sound rated panels and accessories allows a degree of construction freedom not possible with conventional acoustic panel systems. With acoustic Modular Panels, the plant engineer, safety director, OEM manufacturer, architect, or maintenance supervisor can obtain the exact sound controlling structure necessary for each specific situation.

We manufacture sound proof glass having two glasses with air vacuum between both the glasses provide adequate vision of the production process windows can be incorporated into the design. The design of windows, particularly large window areas, requires great care in the details of glass responses. We can manufacture any size.

An anechoic chamber is a room in which the walls, floor and ceiling are lined with sound absorbing material, usually foam or glass-fibre wedges. The lining prevents the reflection of sound from the room boundaries so that 'free-field' conditions exist. The room sounds very 'dead'. Sound measurements are not influenced by the room surfaces, and an anechoic room is an ideal environment for many standard tests such as the measurement of the sound power of a machine, or measurements of microphone and loudspeaker frequency responses.

Floor vibration is up-and-down motion caused by forces applied directly to the floor by people or machinery.

Floor vibration generally makes people uneasy and creates fear of structural collapse, although such fear is usually unwarranted because of the small displacements and stresses that are actually produced. The main factor underlying most vibration problems is resonance, which occurs when a load is exerted on a floor at a particular frequency.

An effective method for reducing floor vibration due to machinery is to isolate the machine from the floor by placing it on anti vibration pads.

We design / manufacture Vibration Isolated floors as per customer's requirement for residential, commercial & industrial uses.

Vibration Isolation Floors is also known as ,Vibration Isolation System, Vibration Isolation Theory, Floor Vibration Material, Vibration Isolated Floors, Floating Floors, Vibration Isolation Material, Floor Vibration Control, Vibration Isolation Pads

Industrial Noise Control & Soundproofing

Industrial noise control is a growing concern in factories, industrial sites, manufacturing and mining facilities. The goal for industrial noise control is to promote hearing conservation while reducing noise levels for personnel to protect employees from hearing loss and increase industrial safety within the facilities.

 Companies are required to comply with industrial safety noise levels within OSHA requirements or other governmental or insurance agency requirements. Acoustical enclosures and machinery enclosures are a very common treatment for industrial noise control requirements.

 We fabricate all of their industrial enclosures to meet the requirements of the environment that it is going into. The acoustical and machinery enclosures are typically made from AudioSeal acoustical blankets. These are very durable vinyl quilted blankets that can be suspended or floor mounted to form any type of industrial enclosure. Metal machinery enclosures are also available.

Noise reduction is achieved with the use of:

Acoustical Blanket.

Soundproofing and isolation products materials  vinyl sound barrier.

Hanging Baffles and banners.

Envirotech Systems Pvt. Ltd.  has the wide range of solutions to your industrial noise issues. Excessive noise in industrial and manufacturing settings not only reduces productivity, it puts workers' health at risk. exposure to loud noise causes stress and hearing loss. We  have assisted  numerous  companies in protecting workers' health, and avoiding  costly insurance claims, by addressing industrial noise

  Acoustic Panels, Baffles and Curtains are just a sample of choices that reduce overall noise and control reverberation in factories, processing plants and other industrial settings by trapping and  dissipating sound waves.  Most of our industrial noise control products are made from Class 1 fire-rated materials.

To control noise effectively, it's important to distinguish between the two types of sound and the medium in which it propagates. Sound waves are a form of elastic waves that occur in any medium that has mass and elasticity. When mass (inertia) enables disturbed particles to transfer energy to the adjacent particle, elasticity enables the disturbed particle to get back to its original position, like a spring. This propagation of momentum from one particle to another explains the manner in which sound waves travel.

Rock wool and fiberglass are great sound insulaters and anything that is rough is also good like spray on foam or carpeting. You install fiberglass or rock wool in your dry wall but that would having to tear it out or you could make holes on your wall and fill it with expandable foam. but the most non invasive choice is to just tack carpeting or a blanket on your wall. However the latter wont insulate as well as the former choices. Carpeting on the floor and ceiling would also help but spray on foam would probley be easier if you are doing the ceiling.

Controlling your level of exposure to industrial noise means you also control product quality, production time, absenteeism,  turnover rates, health care costs and legal expenses all related to unhealthy levels of sound exposure in your facility.

Industrial sound proofing treatments often invoke the use of a combination of acoustical products that are implemented in phases until the appropriate degree of control can be triggered.    The succession of noise reduction treatments in the order to be considered are listed in the drop down menu below.  

With Envirotech soundproofing systems you get the highest quality and most affordable Noise Reduction, Acoustical, and Premium soundproofing

        Soundproofing “Silencer” mass-loaded vinyl (MLV)

A “Limpid Mass Barrier”, it stops sound dead! (Well, almost!) Put in as Floor Mat and Flooring on/in the floor or in your Walls! This material is a tough, wear resistant, heavy (like our lead foil), a “loaded” vinyl which is also available bonded to a 1/4 inch foam cushion to help isolate noise and vibration in the home and in vehicles. 54 inch wide,  3/8 inch thick.

Use this soundproofing in floor & wall Put under your running machines! Very tough and durable. (NOT some cheap ineffective neoprene others are selling as a substitute to ours!)    See also:   Mass Loaded vinyl in combination with a sound Dampening it provides the highest level of sound control in a passive installation.

        Only Three Things Stop Noise

1. Space.   The more space there is, the more noise reduction there is. As an exaggeration, if you are 10 miles away, you will not hear it, except under strange circumstances.
2.  Mass.    A six foot thick concrete wall works great!! If it is heavy, it will work well. Remember, if it does not weigh much it will not stop much.
3.  Dampening.   This requires a little explanation. Like a wine glass, when you make it ring... but you can keep it quiet by holding it. You have dampened the noise by retarding the vibrations. This can be achieved in several ways.
   
   Lead is heavy and soft; the softness makes it also dampen the noise and lead is an excellent noise stopper. Making noise transfer through different layers of material with different densities also helps dampen noise

   Cotton Fiber Insulation

   Natural Cotton Fiber insulation is the successful combination of 25 years of insulation experience and a revolutionary patented manufacturing process that has created a new, superior and safe product. A “Green” material, Natural Cotton Fiber Insulation is manufactured from recycled cotton fibers and natural denim.

   The denim and cotton are also 100% post-industrial, which assures that the fibers are free of any contaminants. Installation is easy, and the absence of fiberglass makes installation much more pleasant. (Cotton Fiber Insulation)
