Trusted on projects where acoustic performance matters
Oil and gas infrastructure, a national space programme, international hotel groups,
multiplex chains and co-working operators across India and the export markets.
Most acoustic problems are one of five. Pick the one that sounds like yours and we
will show you the layer that fixes it, rather than asking you to choose a material first.
Eight brands cover the whole build-up. These are the six that carry most project
work, each with the published figure a specifier will ask for first.
SoundBlanket®
Sound isolation
High-density mass loaded vinyl that goes inside a wall, floor or ceiling build-up to add mass
where there is no room for a thicker wall. Sealed into the construction and covered.
STC 30 at 2.5 mm, STC 34 at 4 mm, measured to ASTM E90. 2100 kg/m³.
Recycled polyester felt pressed into panels, ceiling tiles, baffles, clouds and screens. Cuts
and routs cleanly, takes colour, and holds a Class A surface.
NRC 0.30 at 9 mm rising to 0.60 at 24 mm. NRC 0.90 over 20 mm BassBloc®.
The low-frequency layer. Used in corners and behind other panels where absorption needs depth
and mass. A core material, always covered rather than left exposed.
NRC 0.85 at 20 mm and 0.95 at 40 mm to ASTM C423. Effective 100 to 500 Hz.
Slatted, fluted and perforated timber over an acoustic backing, so the absorption happens
behind a surface that reads as joinery. Auditoriums, boardrooms and lobbies.
Slats NRC 0.75, classified B s1 d0 to EN 13501-1. Perforated NRC 0.70.
SoundBlanket®, BassBloc® and an acoustic finish specified together as one build-up,
for walls and floors where isolation is the whole point of the room.
Up to 60 dB reduction in the assemblies where it has been applied.
A window is usually the weakest surface in a room and the hardest to rebuild. Vindo treats
windows, doors and glass without construction: a dense curtain for traffic and street noise,
hung on hooks with no fixing into the reveal.
Soundproof curtain STC 30 at 10 to 12 mm. Acoustic curtain NRC up to 0.70 to ASTM C423.
Absorption is measured to ASTM C423 and EN ISO 354, transmission loss to ASTM E90,
and surface burning to ASTM E84, with EN 13501-1 where a European classification is specified.
Third-party testing is carried out by laboratories including SGS and ARAI. Where a value is an
in-house or indicative figure rather than a certified one, we label it that way.
Batch checking at the plant: thickness, weight and colour against the inspection
sheet. The certified figures we publish come from third-party laboratories.
Absorption and NRCASTM C423 and EN ISO 354, with the mounting condition stated alongside the figure.
Transmission loss and STCASTM E90 on a complete laboratory partition, not on a single layer in isolation.
Fire performanceClass A to ASTM E84, EN 13501-1 classifications, and UL 94 on the products that carry it.
Batch traceabilityA supplied batch traces back to its production run and its test record.
Submittal documentationTest reports, fire certificates, manufacturer authorisation and statutory documents as one pack.
In-house laboratoryUsed for development and batch checking, never to generate the certified figures we publish.
Mahabir Multi Tech has been making things since 1968, moved into acoustics in 2003
and launched MMT Acoustix in 2014. Every one of the eight brands is manufactured at our own plant at
Palwal, Haryana, which is why thicknesses, densities, colours and sizes can be made to a project
requirement instead of a catalogue.
We make it, we do not buy it inSpecification, supply and accountability sit with one company rather than a chain of
traders. When a project needs a non-standard size or density, that is a production decision
rather than a supplier negotiation.
Made to the requirementThickness, density, colour, size and finish are set per project. Echsorbix alone runs to
more than forty colours, and panels are made up to 3000 x 2000 mm.
Quality system and traceabilityThe plant runs to ISO 9001:2015, with third-party test reports published per product and
batches checked against their records in our own laboratory.
Export supplySupplied to 25+ markets on CIF, FOB and DDP terms, with export packaging and the
documentation and certifications those markets require.
Lead times you can plan aroundStock items dispatch in 2 to 3 working days. Custom and bulk orders typically take 7 to 10,
and the quotation states the lead time for what you have actually specified.
OEM and white labelWe manufacture on an OEM and private label basis for brands and industrial partners, matched
to a specification or to a sample you send us.
Our own plant at Palwal, Haryana. Every one of the eight
brands is made here.
Share the project and our team will come back with the recommended system, the
test data behind it, quantities, pricing and an expected lead time. Quotes are answered within
48 hours, and the same day when the first message already contains what we need.
Acoustic and soundproofing materials across eight brands: MMT Acoustix and Turbo acoustic foam, SoundBlanket mass loaded vinyl, Echsorbix PET felt panels, SoundaXe wooden acoustic panels, BassBloc low-frequency absorbers, Impactpad impact isolation, and the adhesive range, alongside soundproof curtains, acoustic carpet, fabric panels and door seals.
What is the difference between soundproofing and acoustic treatment?
Soundproofing stops sound passing between spaces and is built into the construction with mass, decoupling and airtightness. Acoustic treatment shapes how a room sounds and is applied to the surfaces. Absorptive panels on a wall do not reduce what passes through it, which is the most common misunderstanding in this field.
What is the MMT Acoustix three-layer system?
A blocking layer, a damping layer and an absorptive finish. SoundBlanket provides mass to block transmission, BassBloc damps low-frequency and structure-borne energy, and an acoustic panel finish controls reverberation inside the room. Each layer answers a different problem, so omitting one undoes the others.
Where does MMT Acoustix manufacture and supply?
Manufacturing is at the Palwal plant in Haryana, India, across three manufacturing units, with supply to projects across India and 25+ export markets.
Are the products tested and certified?
Absorption is tested to ASTM C423 and EN ISO 354, transmission loss to ASTM E90, and surface burning to ASTM E84 with EN 13501-1 where a European classification is specified. Test reports are issued alongside the supply.
How do I get a specification for my project?
Send the drawings, the room volumes and the target NRC or STC, and the system is specified against those figures with test reports issued alongside the supply.
