Are you tired of bulky, traditional room dividers that limit how you use your spaceEvery space has a sound story. Whether it is a boardroom where deal-making conversations get swallowed by echo, a school auditorium where children cannot hear their teacher clearly, a recording studio buzzing with unwanted hum, or a manufacturing plant where noise levels are dangerously high β poor acoustics cost real money, damage health, and destroy experience. This is precisely where a qualified acoustic consultant becomes not just useful but absolutely essential.? Looking for a flexible, modern solution that lets you transform any room instantly?Β Sliding partitionsΒ are the future of intelligent space management. Whether you call them aΒ sliding partition wall,Β sliding folding partition,Β room partition sliding doors, orΒ sliding glass partition, these systems deliver the perfect balance of functionality, style, and convenience.

We help to design, assess, manage, and control sound and vibrations in the built environment. We provide consultancy for the design or assessment of acoustics in homes, workplaces, leisure facilities, the outdoor environment, and so on. We provide good speech intelligibility in theatres, restaurants, and railway stations, enhancing the quality of music in a concert hall or recording studios or suppressing noise to make offices and homes more productive and pleasant places to work and live, making sure that the sound systems are heard with clarity in even the busiest transport hubs.
We design innovative virtual listening environments, allowing our clients to hear the sound of existing spaces, and to test the sound of designs. We are practical people and creative problem solvers with a broad knowledge of the subject, legislation, and standards.
We as consultants contribute to pleasant and productive environments in schools, workplaces, homes, and hotels. We excel in these environments. We also specialize in specific areas of acoustics, such as; audio and hi-fi design, auditorium and concert hall design, broadcasting and telecommunications, laboratory design, and so on. Our insight, together with our experience in managing noise and vibration issues, helps us resolve potential hurdles at the planning stage, win acceptance, and secure consent.
We follow a set of strategies to reduce noise pollution by reducing noise at its source, by inhibiting sound propagation using noise barriers or similar. Our control at the source is the most cost-effective way of providing noise control. Other techniques we use to reduce product noise include vibration isolation, application of acoustic absorbent, and acoustic enclosures.
Packsound, operating under Ecotone Acoustic Limited, is one of India’s most respected acoustical consulting firms. With a principal consultant carrying over 25 years of field experience and a multidisciplinary team of acoustic engineers, designers, and project managers, we guide every client from the earliest planning stage all the way to commissioning and post-installation testing. If you are searching for a trusted acoustic consultant in India who combines deep scientific knowledge with practical, budget-conscious solutions, you have found the right partner.
An acoustic consultant is a specialist who studies, measures, and controls sound within built environments. The work spans two distinct but complementary disciplines: architectural acoustics (how sound behaves inside a room) and noise control engineering (how unwanted sound is prevented from entering or leaving a space).
Where a general contractor sees walls, floors, and ceilings, an acoustic consultant sees surfaces that reflect, absorb, or transmit sound energy. Every material choice, every room dimension, and every ventilation duct is a variable in a complex acoustic equation. Getting that equation right from the outset is far cheaper than corrective treatment after construction is complete.
Our team at Packsound works across the full acoustic lifecycle: site assessment and measurement, acoustic modelling and simulation, material specification, coordination with architects and MEP engineers, construction-phase oversight, and final acoustic testing. We also provide virtual listening environments that let clients hear how a space will sound before a single brick is laid β an invaluable tool for high-stakes projects such as concert halls, courtrooms, and broadcast studios.
Understanding what an acoustic consultant does requires a brief look at the physics they work with every day.
When sound waves hit a surface, a portion of the energy is absorbed and converted to heat rather than reflected back into the room. Materials with high absorption coefficients, such as our fabric-wrapped acoustic wall panels and acoustic ceiling tiles, reduce reverberation time and make speech clearer. Absorption is measured by the Noise Reduction Coefficient (NRC), where 1.0 represents total absorption and 0.0 means zero absorption. Packsound’s products achieve NRC values ranging from 0.75 to 0.95 depending on product type and installation.
Hard, flat surfaces like concrete walls and glass facades reflect sound energy back into the room, creating flutter echo β the rapid, repetitive echo you experience when you clap in an empty gymnasium. Acoustic consultants design surfaces to either absorb this energy or scatter it uniformly through diffusion, preventing the build-up of hot spots and dead zones in a room.
Reverberation time is the duration it takes for sound pressure to drop by 60 dB after the source stops. A concert hall optimised for orchestral music might target an RT60 of 1.8 to 2.2 seconds. A speech-focused conference room performs best at 0.4 to 0.6 seconds. Getting this wrong in either direction degrades the intended use of the space dramatically.
Sound Transmission Class (STC) measures how well a partition stops sound from moving between spaces. Our soundproof fixed partitions and drywalls and acoustic wooden doors are engineered to meet specific STC targets, ensuring privacy in legal chambers, confidentiality in corporate boardrooms, and silence in recording studios.
In industrial and mechanical environments, vibration from rotating machinery travels through structures and re-radiates as audible noise in occupied spaces far from the source. Acoustic consultants specify isolation mounts, floating floors, and resilient connections to break these transmission paths at their origin.
The global shift to open-plan offices created a productivity crisis rooted in noise. Research consistently shows that uncontrolled office noise is the single largest contributor to employee dissatisfaction and cognitive fatigue. Our acoustic consultants assess your existing office or review drawings for a new fitout, then recommend a layered solution combining acoustic hanging baffles, soundproof sliding partitions, and acoustic office pods to create zones of appropriate sound energy without sacrificing the open, collaborative feel.
Performing arts acoustics demand the highest level of consultant expertise. Every seat in a 2,000-seat auditorium must receive sound of consistent quality and character. We have delivered end-to-end auditorium acoustic treatment projects across India, specifying panel geometry, seat absorption, stage canopy design, and reverberation chambers as needed. Our work on school auditoriums has included achieving optimal RT60 performance as per IS:4954 guidelines β the Indian Standard for auditorium acoustics.
A recording studio is arguably the most demanding acoustic environment an engineer will ever work in. The control room must have a flat frequency response with no room modes colouring the sound being mixed. The live room must offer variable acoustic character to suit different musical genres. Vocal booths demand near-anechoic conditions. Our consultants have designed and overseen complete studio builds achieving professional-grade sound isolation and near-zero reverberation β enabling pristine, commercially viable recordings from day one.
Noise in healthcare settings is a clinical concern, not merely a comfort issue. Studies have demonstrated links between ICU noise and delayed patient recovery, sleep disruption, and increased stress hormone levels in both patients and nursing staff. Our acoustic consultants specify and source materials that meet healthcare acoustic standards, paying particular attention to speech privacy in consultation rooms, low reverberation in wards, and vibration isolation from HVAC and medical equipment.
Children with hearing difficulties, those learning English as a second language, and young learners in general rely heavily on high signal-to-noise ratio in classrooms. A noisy classroom is not just an annoyance β it is a barrier to learning. Acoustic consulting for schools involves balancing absorption to reduce echo without creating an uncomfortably dead acoustic environment, and ensuring partitions between classrooms meet minimum STC requirements per national building codes.
In a restaurant, acoustic design determines whether guests enjoy a lively, buzzing atmosphere or find themselves shouting across the table. In a luxury hotel, STC-rated partitions between guest rooms are a basic expectation. Our consultants work with hospitality designers to specify mineral fiber acoustic ceiling clouds, fabric acoustic panels, and movable wall partitions that meet acoustic targets while enhancing the visual identity of the space.
Occupational noise is a regulated health hazard in India under the Factories Act and IS:3483. Industrial acoustic consulting involves noise mapping, identifying dominant noise sources, and implementing engineering controls. We design noise barriers, acoustic enclosures, vibration isolation systems, and hearing protection zones to bring industrial clients into regulatory compliance β and protect their workforce.
Transport infrastructure presents unique acoustic challenges. Road and rail tunnels amplify sound dramatically and can become dangerous acoustic environments for maintenance workers. Public address systems in busy stations must deliver intelligible speech announcements above high ambient noise floors. Our specialist tunnel acoustics service addresses these challenges through detailed simulation, surface treatment specification, and PA system acoustic design.
Our consulting methodology is structured, transparent, and collaborative. Here is how a typical engagement unfolds.
Stage 1 β Initial Brief and Site Visit: We begin with a thorough briefing to understand the space, its intended use, applicable standards, budget, and timeline. For existing buildings, we carry out a physical site survey and measurement session using calibrated sound level meters and acoustic analysis software.
Stage 2 β Acoustic Modelling and Simulation: Using specialist software, we build a three-dimensional acoustic model of the space. This allows us to predict reverberation times, sound pressure levels at different positions, and the impact of proposed treatment strategies β all before any money is spent on materials.
Stage 3 β Design and Specification: We produce a detailed acoustic design report specifying every treatment element: panel types, dimensions, positions, and quantities. We coordinate this with the architectural and interior design team to ensure acoustic requirements are incorporated without compromising the design intent.
Stage 4 β Product Supply and Installation Oversight: As a manufacturer of acoustic products through Ecotone Acoustic Limited, we can supply every specified element from a single source β eliminating coordination risk and ensuring the installed product matches what was modelled. Our installation teams are trained and supervised by our technical consultants.
Stage 5 β Testing and Commissioning: After installation, we carry out objective measurement of the completed space to verify that acoustic targets have been achieved. Where results fall short, we identify corrective measures promptly. A formal acoustic commissioning report is issued upon sign-off.
Most acoustic consultants specify products from third-party manufacturers, which introduces a layer of procurement complexity and risk. If a specified product is unavailable, substituted, or installed incorrectly, the consultant has limited recourse. At Packsound, our consulting team works hand in hand with our in-house manufacturing and product development teams.
This means that when our consultants design a solution using grooved wooden acoustic panels, micro-perforated metal ceiling panels, or composite acoustic panels, they know precisely how those products perform in practice because they have tested them themselves. Product datasheets, NRC certificates, STC ratings, and fire compliance documentation are all available instantly. There is no gap between design intent and physical reality.
This integrated model also delivers significant cost savings. By eliminating distributor margins and reducing procurement cycles, clients typically receive higher-specification solutions at lower overall project cost than they would achieve through a fragmented design-supply model.
A question we hear regularly is: can we sort out the acoustics after the building is finished? The honest answer is yes β but at a significant premium. Post-construction acoustic correction is almost always more expensive, more disruptive, and less effective than getting the design right at the outset.
Consider a case where a developer completes a 200-seat multiplex cinema only to discover that sound bleeds between adjacent screens, ruining the viewing experience. Corrective treatment at that stage requires demounting interior finishes, installing additional mass-loaded barriers, replacing panels, and potentially closing the venue during the remediation period. The cost is routinely three to five times what proper acoustic design at the planning stage would have cost.
Our acoustic design and consultancy service is structured to add maximum value at the earliest possible stage. We work with architects, structural engineers, and interior designers during the schematic design phase β when acoustic requirements can be accommodated without redesign cost. This is the stage at which material choices, partition types, floor-to-ceiling heights, and mechanical equipment placement are still fluid and can be optimised for acoustic performance.
When clients ask what an acoustic consultant recommends, the answer depends entirely on the noise problem and the space. However, the following engineering controls represent the core toolkit of every competent acoustic consultant.
The most cost-effective noise control strategy is always to reduce noise at its origin. For mechanical plant, this means specifying quieter equipment at procurement stage. For industrial machinery, it means vibration isolation mounts, damping treatments, and acoustic enclosures built around the noisiest equipment. Our consultants assess source noise levels and specify control measures before specifying any receiver-end treatment.
When source control alone is insufficient, barriers and enclosures interrupt the propagation path between the noise source and the receiver. Packsound manufactures a comprehensive range of noise barriers including polycarbonate noise barriers, metallic noise barriers, and mobile noise barriers for applications ranging from highway noise mitigation to temporary construction site noise control.
Within occupied rooms, acoustic treatment controls reverberation, echo, and background noise levels. Our consultants specify combinations of acoustic wall panels, acoustic hanging clouds, acoustic foam panels, and fiberglass acoustic panels calibrated to achieve the target RT60 and NRC for the specific room use.
Where acoustic privacy is required between adjacent spaces, our consultants design partition assemblies with the necessary STC rating. This includes specification of soundproof fixed partitions, soundproof sliding folding partitions, and acoustic wooden doors with appropriate seals to prevent flanking transmission through gaps and air paths.
The acoustic consulting market in India includes firms of widely varying capability. Here are the criteria that genuinely distinguish excellent consultants from average ones.
Measurable experience: Ask for a portfolio of completed projects with pre- and post-treatment acoustic measurements. Any consultant worth engaging will be able to demonstrate quantifiable improvements in RT60, SPL, or noise level across completed projects.
Simulation capability: Modern acoustic consulting requires computer modelling. If a consultant is relying purely on rules of thumb and past experience without simulation software, the quality of their predictions will be limited.
Product independence or integrated supply: Either the consultant should be genuinely independent and specify on merit, or (as in the case of Packsound) the consulting and supply arms should be genuinely integrated with verified performance data for all specified products.
Knowledge of Indian standards: Indian building codes and acoustic standards differ from European and American norms in important ways. Your consultant must be familiar with IS:4954, NBC 2016 acoustic provisions, Factories Act noise limits, and applicable MOEF environmental noise regulations.
Post-installation accountability: The best consultants include a commissioning measurement phase in their scope of work. If your proposed consultant has no mechanism for verifying the acoustic outcome, the design risk sits entirely with you.
