Acoustic Foam

Acoustic Foam
We offer the complete range of acoustic foam in order to meet your acoustic needs. Order by the pack and/or larger sizes for Note regarding custom cut pieces: We try to provide one seamless piece for your order. However, since this foam is manufactured in pairs, we will sometimes send two pieces of half the size you've ordered

Acoustic foam is not fire retardant. Use at your own risk.

For total sound blocking it is necessary to control the flow of air into and out of a room. Sheet rock walls, ceilings, and floors should be further insulated with 6mm. Acoustic foam is best applied to your walls and surfaces with a heavy staple gun or our adhesive spray. Remember, most acoustic sheets larger than 82" x 96" will have seams. During the vacuum packing process (for shipping) these seams can open. It is recommended that you purchase a can of foam glue to mend any seams that may have ripped during shipping.


Acoustic Curtains

Acoustic Curtains

We design the Soundproof Curtain 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 soundproof 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 of acoustic curtain depends on the weight of the fabric used, the depth between the soundproof curtain and the wall and the degree of pleating.

ACOUSTIC PERFORMANCE


Room Acoustic

Room Acoustic

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.


Soundproof Enclosure

Soundproof  Enclosure

We design Soundproof Enclosure to control noise levels of engine driven sets, compressor, and pump systems. The performance of our soundproof 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.


We design soundproof enclosure in such a way that reduces noise and meets the ISO 14001 norms of environment. All soundproof enclosures are manufactured to prevent the excessive noise level and its dire effects on the workers. In this regard we use various techniques & properties for noise control.

 

As per client's requirement, we design and manufacture customized acoustic enclosure, inbuilt with acoustic normal door, vertical sliding door on front side with view panels, hinged doors with neoprene gaskets on sides & rear, soundproof glass window (vision panel) of 8 mm thick toughened glass, perfectly guided (by grooved pulley) for smooth friction less operation, operated by pneumatic cylinders with open and closed end limit switches and control, proper air circulation ( arrangement of axial flow fans), bolted up panels for easy maintenance access, wire mess (3 mm) on the roof, panel external sheet 2.0 mm CRCA sheet, inner side 1.0 mm perforated sheet, 100 mm cavity having filling soundproof material.

To achieve the desired dB (A) level we use the various range & property of panels by using the insulated and sound dampening material. Inbuilt attenuated air intakes, sliding or hinge type door and acoustic louver for hot air discharge increase the performance of enclosure. All dismantle parts of soundproof enclosure are power-coated and finally installed by our execution tem at site.

Our soundproof enclosure offers following benefits:

  • A simple and cost effective solution for noise reduction up to 30dB (A)
  • Full installation service
  • Vibration isolation, shock-resistant systems
  • Glazed viewing panels & internal lighting

    Anechoic Chamber

    Anechoic Chamber

    The development and evolution has taken place in the design and construction of acoustic test facilities. Today Envirotech Systems provides the most advanced design and high performance anechoic chamber, semi anechoic chamber, hemi anechoic chamber, portable anechoic chambers & engine test chamber acoustic.

    The effectiveness of an anechoic chamber is measured in dB of rejection, which is the ratio of direct sound to reflected sound inside the room. Our designed Engine test anechoic chamber provides better than 80dB rejection from 20 kHz down to 80Hz, which is excellent in term of performance for a medium-sized chamber.


    Acoustic Louver

    Acoustic Louver

     Acoustic Louvers & sound Attenuators

    Acoustic louvers are used to prevent noise breakout from an air inlet or outlet of a plant room, building or enclosure while allowing ventilation air transfer. They have varying acoustic performance depending on the type of aerodynamically designed blades is used and the depth of the acoustic louver demanded by the design.

    Noise Barrier

    Noise Barrier
    Absorptive / Reflective Noise Barrier :

    Sound absorptive surfaces reduce reverberant build-up between parallel barriers and other reflective surfaces and increase the ability of barriers to attenuate noise.

    The absorptive face consists of a black breathable membrane, 25 x 25 black weldmesh and 17 vertical chamfered timber trims per 2.4 metre bay. A five vertical trim finish is a more economical option where blending with the environment is not so crucial and a tough industrial face can be offered with heavy galvanised weldmesh.

    In sensitive residential areas, where planning / conservation constraints are strict, the absorptive face may be finished with willow / hazel woven hurdles or thin vertical feather edged pales. This type of finish reduces the absorptive performance of the barrier slightly but there is a slight gain in the airborne insulation.
